Plug and play Harness for Dash and Footwell lighting for the 23 TRD Pro

There’s a few other “how to add accent/mood lights to the dash and foot wells” on the forum but I was able to come up with a way that doesn’t involve splicing into any of your oem wiring or using tape to hold wires in place behind a factory plug. So thought I’d create a separate thread.

This process still requires you to splice together and build your own harness. However you can build an OEM like harness using original oem harness parts. It still also involves some cutting of the dash trim pieces. The most important part of this modification is that it doesn’t involve cutting/splicing into a Lavender colored wire. Lavender wires are aluminum wires and Toyota states to not splice into them for power or signals.

The following part numbers were used:

81080-0C170 – Driver side dash light and bracket
81080-0C190 – Pass side dash light and bracket
81080-0C010 – Foot well lights (Qty 2)
81080-0C040 or 81080-0C050 – Door mood light harness (Qty3) I used 0C040 for all three.

20 gauge wire. To start I used about 8 feet and cut off what I didn’t need. I think I only ended up using around 6 feet total.
3M friction tape
Other various tools/supplies: solder, heat shrink tubing, wire cutters/strippers, Dremel tool or the like to cut the two dash trim bezels to allow the light to shine through.

Following this method the foot well and dash mood lights will come on depending on the position of the headlight switch. When the switch is either in the parking light, headlight or Auto position the mood lights will come on. They will also dim with the factory dim switch.

I compared a lot of the oem wiring mood system found in my wife’s Platinum Seqouia to that of my Trd Pro Tundra. The factory mood lights are tied to the Auto light sensor in the car just as if you had the headlight switch in the auto position. However they also operate with the proximity system, ie when you walk up to the car with the key the mood lights illuminate. They also dim and turn off independently than the rest of the cars lighting via the mood switch in the overhead console. To get the mood lighting to work this way it would require a lot of work and adding more wiring into existing harness and into the main body ecu. I believe the way I’ve added it will work fine for me.


To begin:

Part# 801080-0C040 has one female end and two male ends on the harness. One of the male ends comes with a light plugged into it. You will use a total of 3 of these harnesses to build a new one. You will be cutting all of the plugs off leaving a pigtail of wiring to build your new harness.

My starting location for the new harness will use the male and female end that are closest to one another from one of the 81080-0C040 harnesses. Meaning you will cut the harness after the oem splice point so that the male and female plugs are together on one harness. Ie just cut the male end off that is furthest away from the male and female end. Pic below shows the one male end furthest away cut off.

With the cut end of the 0C040 harness now spliced onto your new 20 gauge wiring I ran it out 8 feet. I now have the main part of my harness. Took it out to the truck and ran it behind the dash. Start with the OEM plugs at the glove box.

The tap/plug in location to get power for your lights will be plug I80 on the wiring schematic, the glove box light. You will unplug the harness from glove box light and plug your new harness female end into existing I80 plug. The male end from the 801080-0C040 harness will now plug into the glove box light.

Run the harness from the glove box to the far right side of the dash and down, back across the foot well trim on the lower part of the dash, back behind the center console, to the lower side of the foot well area on the driver’s side and then up to the last light location beside the cluster. I taped the harness to locations I thought I could tape or zip tie it up an away for when I made my final install. I then went back along the harness and placed tape on the harness in areas on the wire where I was going to add my new splices for the additional 4 plugs I was going to need. Starting with the passenger side I marked the location for the light plug for the light under the heritage trim on my TRD pro, then the passenger foot well, then the driver’s foot well and the end of the harness would be the light beside the cluster on the dash.

I pulled the harness back out from under the dash and added the additional wiring with the male plugs cut from the other 0C040 harnesses to the locations I marked with tape. I actually added a little extra wire to those cut sections from the 0C040 harness to the ones I used for the foot well lights, this way when removing those lower trim panels in the future there was a little more play in the harness. I finished the harness by wrapping the whole thing in 3M friction tape; it looks identical to the tape used on the 0C040 harness.

Photo below compares the lower dash trim panels. TRD Pro at top and Platinum from my wife's Sequoia. Platinum models and up had the additional pad/insulation on them. The foot well lights snap into place in the center of the white pad. Same location for the trim panel on the TRD Pro. Purpose of the pad found in the Platinum? Noise reduction? Insulation?

Removing some of the dash trim to get access behind the dash is not hard. Use a plastic pry tool. The hardest part is getting the glove box light unplugged and plugged back together without dropping the glove box itself. It can be done just a bit of a tight squeeze. I didn’t drop the box. I watched this video that helped me dismantle the needed pieces to get access behind the dash.

Other small notes:

The lights that come with the door harnesses, 81080-0C040 and 81080-0C050 are the pocket lights for the doors. They have a diffused cover on them, compared to the lights that are supposed to be in the foot well which are completely clear, 81080-0C010. You could use either light as the harness will accept either one but the door bulbs with the diffused cover are a bit dimmer/softer. I choose to go with the 0C010 bulbs, which brought the total cost of the project up an additional $30.

For those that would want to add foot well lighting to the rear under the front seats you should be able to apply the same concept of building a harness going off the center console box light. You would just need to find a way to mount the lights.

You will have additional lights left over from the harnesses, especially if you elected to purchase the 0C010 lights.

The driver’s side dash light bar snaps right into place with any modification. The passenger side light bar does not as the dash/trim panel does not have the mounting holes already punched out. You will need to drill/create those holes. The light bar has a total of 4 mounting clips but you will only be able to use the two most center clips. My TRD Pro did not have the tabs to create the punch outs for the outer most clips. It mounts just fine without the outer tabs. The punch outs need to be about a ¼” rectangle. They are identical to the others in the dash shown above in the photo. I used a drill bit and then an xacto blade to carve out these holes.

You will also need to trim your dash bezel covers to allow the led bar lights to shine. I compared my bezels to that of the bezels in my wife’s Platinum Sequoia and was able to get a good measurement of how much to trim. The driver’s side is a simple straight cut. The passenger side needs to be trimmed down at an angle as each end has a different measurement.


Measurement closest to the vent that is attached with a screw is: 1 5/8”

My only regret, I didn’t take a photo of my harness I built, lol.


Not sure on all trims but for 24 models I know the TRD Pros do have the foot well lighting now in them. However I believe they are wired into the door switch circuit thus they would only come on when the door is opened and turn off once closed. Maybe a 24 owner can verify.

 

darn, maybe dropbox doesn't allow the pics to be shown on the forum. I've replaced them with links that I think might work until I can figure something else out.

 

Great work man, I have lights in the garage to do this for months and haven’t gotten around to it yet…glad my dash video was helpful!…awesome job!

 

Are these so you can see your feet while you drive? I had this in the driver side on my ‘18 Tundra and never really knew what it was for.

 

Great job and pleased to see someone figured this out. However, I am looking just to add the footwell lights and even though the pictures and parts list provided are of some assitance I am still having issues following this installation.

Pictures of the finshished completed harness before installation, how the harness is laid out across the front of the cab and plugged into the I80 plug along with and details on where to cut and splice into the purchased harnesses would help. Which parts do I really need just for the footwell lights?

 

Maybe this will help. Shot this really quick.

If you're just doing the foot well light lights I believe all you'll need is:
81080-0C010 – Foot well lights (Qty 2)
81080-0C040 - harness (qty 2)

Then build the harness.

 

Thank you very much Zeke21, this helps alot. I thought the glovebox light was a switched light when you open it but I guess not.

I sat down and sketched it up and I think I have it figured it out now. I might just go out an buy three of the OC040 harness so that I will have enough connectors/pins (one male connector short) to use the diffused lights that come with this harness as footwell lights for the back seats. I will need to figure out how to mount those lights but it should not be too difficult.

 

It is not switched.

Technically you could very easily daisy chain multiple copies of that harness and not have to cut a single wire...but it wouldn't look good and you'd have a ton of extra plug hanging around. Getting access to the center console light is even easier. I'd plug into that for the rear seats.

 

@Zeke21 superb instructions; clearly laid out. I have been planning to add footwell lighting in the front, rear and door lighting for a few weeks now. Decided to try to stay as OEM as possible with no factory wire splicing so decided to give it a go with the front footwell lighting first; install very similar to yours; sans the dash lights. Also, inspired by @RatPanda - appreciate your support too!

Parts purchased:

• 81080-0C050 (qty 2) this is the harness with two males and one female and included one of the diffused blue lights

Anyone know the difference between 81080-0C050 and 81080-0C040?

Harness Build

1. Cut a male end off of one of the harnesses and remove light
   • I'm saving this harness to use for the rear footwells when those lights are delivered
2. Ran approximately 5 ft of 20 gauge wire and used that male end for the driver side and tapped into the other harness
   • Probably could have got away with 3-4 feet but wanted some additional slack

Routing the Harness

1. Connected female end of the harness to the I80 male connector (where the original glovebox light was connected)
2. Routed the passenger footwell light down behind the passenger airbag near areas where I could zip-tie and connect everything
3. Then routed the driver portion of the harness starting from behind the center console on the passenger side to to the lower side of the foot well area on the driver’s side (I used a grab easy drain snake)

Final Product
Pretty pleased with the outcome. I ordered two 81080-0C010 to replace the front footwells lights to be bit brighter but plan to use the diffused lights for the rear footwells.

TIP
You will need to likely extend the passenger footwell lighting on the harness. I attempted to use as stock and with the glovebox installed the harness directly impeded access to the cabin air filter box. I ended up pulling the entire harness out of the truck and extended that portion by about 12 inches and that did the trick. Also the glove box is a PITA.

Cheers!

 

EXCELLENT write up!!

 

I can confirm that this is the case on a 24 SR5 TRD sport.

 

@poolgreenlife I believe the only difference between the two different door harnesses might be length of the wire and connector. I'll know for sure soon as I've ordered both as I prepare to work on the door lighting next. Nice work on the harness.

 

I have a 24 SR5, mine came with the footwell lighting (only works with doors open) AND it came with the accent light in the center console where your phones are supposed to sit. However, I was surprised that I didn't have a glovebox light! Also no "pre-existing" I80 plug either. I already have aftermarket switches installed in the panel to the left of the steering column so that's where I ended up tying into the lights so they would come on with the other interior lights. I used the C40 harness and light for my glovebox light and to connect the light bar on my dash and worked my way over to the driver side dash light then down to my switch panel.


Also important to note on the SR5, it has the storage space built in, whereas the higher trim levels like yours has a dash pad- not sure why Toyota would take this space away for higher level trims So the mounting of the light bar to the dash is not possible using the red clips because the storage bin utilizes the dash first. If one were to try and mount the light bar first, you would have to cut a slot in the top of the storage bin. I ended up using double sided sticky tape to hold my light bar to the dash because even if I made the correct holes, the red clips would not reach (as you can see in my picture) and trimmed my dash bezel like you did so the light would shine down into my storage bin.

 

Finally started my footwell install today. Completed the front but still need to fine tune the back.

 

Do you have the part# for this light bar for the dash?

 

There are two LEDs for the dash. I have the PN on my build thread.

 

Just called up my local canadian parts counter to see what i'd be looking at....

the dash lights are 72.05 and 84.93 (left and right)
the Foot Well lights are 86.74 for the 2 of them
and the harness are 72.05 each....

it may be cheaper for me to order them from sparks lol - looking for the door light part # now too

 

Don’t forget 25s are white now. The blue PNs won’t match.

 

Ok so we have a Canadian Sparks - Toyota Online Direct Canada...Buy OEM Toyota Parts | Toyota Online Parts Depot

Here are all the part # and quantity you should need... 3 harnesses for the dash lights and one for each door * note the difference between the 050 and 040 appear to be front and back door harness , not left and right. this adds up to about 100$ cheaper than Rave Offroad's kit... if it's worth it to you , pls feel free to support local businesses. I prefer to cut out the middle man on OE parts.

darn near 900$ CAD for some mood lighting , Duty would likely be at least 150 so its still cheaper than sparks , but wow - that's a lot of dough.

 

Did the whites supersede the blues? Or are they different part # ? These are the original part numbers

 

The whites are new or different part numbers not superseded. Just don’t know what the new part numbers are. Yes, I’ve purchased all the PNs you’ve listed when I had my 22.

 

For the SR5 guys - anything for the puddle lights/ bottom of door card? I popped out my reflector and didnt see a wire there to use for puddle lights. Did I miss it or is that just poverty trim problems. I do have the footwell, phone and an LED in the headliner too- but no CC and puddle lights

 

Anyone ever come up with an ingenious way to mount footwell lighting under front seats for the rear passengers?

 

There is fixed harness connection under each seat. I think it's for the power seat motors. I just used a ty-wrap and secured the footwell light tightly to that connection on each side.

 

Velcro comes in the rear add on kit. Done it on 2 tundras.

 

For anyone interested, I just installed a VLED series of kits for my footwell lighting. Did it for front and back and they come on at a high setting for door open, like the OEM ones did then come in a low setting at night when the headlights come on. Here’s my walkthrough:

 

Great write up. Glad to help out.
