Morimoto XB Gen 2 Issue for 2020 Tundra

Hi all, so I have a 2020 TRD Pro with full LED OEM headlights. I just installed a pair of gen 2 morimoto xb headlights. I had to purchase a separate wiring harness for my configuration. Anyways, I followed directions and connected the harness to the headlights, then connected all the plugs from the truck harness to the headlight harness.

I noticed my signals are not sequential. Anyone know how to make them sequential? (Thats kinda what I paid for in this upgrade....)

Also, does anyone who switched out their 2020 led headlights for morimotos know which fuse to tap into for the DRL tap? There was a 7.5 led light fuse I tried to use but it caused the DRLs to remain on regardless (regardless as in even when I shut off the car and lock my doors). So for now I left the drl wire tap disconnected and the drl/signal lights only come on when I lock/unlock the truck or I use my turn signals. I would the drl function back but am unsure which fuse to tap.

Hopefully someone can help... it's a bit frustrating as I thought it was plug and play and assumed the sequential mode was the default.

 

The sequential mode is activated be leaving the connector unplugged. I can look in the morning to see which fuse location I am plugged into.

 

Dude, thank you! Do you know which connector is to be left unplugged?

 

Nvm, the instructions say this one.

 

So I tapped the drl fuse tap to a 7.5 amp fuse labeled USB and disconnected the sequential connector so now my sequentials and DRLs work.

New problems:
-Tail light driving lamps now do not come on at all. The taillight brake clamps and turn signals work as they should though. I have the morimoto tail lights.

-Also, while the DRLs work, the drl light output remains constant. Same light output whether or not low beams are on. I was of the impression the DRLs decrease 50% output when low beams are on.

 

I wonder if I was supposed to plug this extra connector in?

I left the harness out because initially my turn signals would not work when I had it plugged in. I assumed maybe it was for the halogen headlight harness.

 

Well. I figured it out. I had to move the white/black wire from each turn signal connector and relocate it to the middle pin. To make life easier, I used the extra signal adapters that were included with each kit and just repositioned the pins.


Ended up tapping into the 7.5amp USB fuse but I may end up moving the drl tap to a 10amp fuse.

Also, just like with another user on here who had the same issue with a 20 TRD pro, I had to replace the 10amp TAIL fuse inside the truck. Now my running lights work as they should. Best part about this fix was I didnt have to remove my grill or headlights again.

Now... I still have one minor issue left:

My DRLs dont seem as bright as the OEM TRD pro DRLs. They are supposed to brighter without the low beams and then dim to about 50% output with the low beams on. Right now they are the same output with or without the low beams on. I sent an email to morimoto so just waiting to see what they say.

 

New question.... do the amber DRLs only come on 100% when set to auto? Because that's what I've noticed. When I turn my stalk to the DRLs, the DRLs are at like 50% power, same as when low beams are on.

 

The DRLs are only at 100% when the low beams are not on. They dim to 50% with the headlights. If they are installed using the fusetap, the DRL function on the stalk no longer works.

 

So should I remove the drl fuse tap? I currently have the fuse tap installed and I have been wondering why my DRLs never got super bright like OEM. Last night I put the stalk in auto and bam, full power DRLs. Every other option on the stalk has the DRLs at 50%, even DRL mode, which kinda drives me nuts because the OEM DRLs would be 100% at the stalk DRL position.

 

As I was mentioning earlier, the fusetap makes the DRL position non-functional. It is due to the way that the Tundra is wired. It still functions as normal on the 4Runners. I have the white DRL's and mine are full brightness when all lights are off. They dim to 50% once the parking or headlights are turned on. he fuse tap should have 10 amp fuses in both slots. Which spot is the fusetap plugged in to?

 

Do you run the drl fuse tap on yours?

 

Yes.

 

I tapped mine into a USB fuse. I think it was a 7.5 fuse. Bottom fuse tap in pic below.
