Looking for adapters or wiring schematics to put 2018(3rd gen) seats into a2013 (2nd gen)

Can anyone help in the install of these in my truck. They are brand new with 8 way adjustments and heat. If I can not install them I'd be willing to part with them if interested. Thx for any help

 

JRZ are my initials. Lol. What year are these seats?

 

2018

 

How much are you asking for?

 

I'd rather install them in my truck. I paid 2500 for them so if I can't get them installed then I'd have to be in that range thx

 

Ouch. There might be another member here that can chime in on this. Good luck with the install.

 

I did just post so I'm getting to see if there is someone here that can point me in the right direction

 

Does your truck have any power seats currently? Nice score, I’ve been wanting to replace my fronts for some time now as the drivers is bagggged out.

 

@Roman could get you parts numbers for oem harnesses I’m sure

 

Yes. Have power. No heat though. Mine are bagged out too lol

 

Should have a look at you fuse panels and see if the heated seat wiring is in place. That’s where I’d start

 

Good call. That's a start. Thx

 

Hit the wiring diagrams link in my signature.
You’re gonna need to look at a LOT of them and compare each circuit and plug.
The 2021 diagrams will cover the 2018.
The 2010 diagrams should be close enough to your 2013.

You’ll need to research:
Power seat adjustment drivers and passenger)
SRS/airbag system
Seat heaters
Occupant sendors (might be in the seat adjustment)

good luck!

 

Being the seat heater on/off switches are in the climate control of a 2014 & up, you'll have to rig your own switches and wiring for them.



I added seat heater to my 2014 SR5.
I tapped into the 12volt power plug circut in the console.
You can figure out which wires do what and just add your own switches..

Something like one of these for both..



I used these and mounted them in the console...





Some 2015 wiring diagrams that might help you..



Heater wires are in this connector under each seat.
Corresponding to the pins in the diagrams above.
QY2 on the right seat.
PZ1 on the left seat.

 

This is how my 2014 power seat is set up.
Not sure if your 2013 would be much different..

There should be 3 connectors in your truck under the seat:
yellow air bag connector
P7 small white connector, seat belt warning and seat position air bag sensor
PZ1 a larger white connector.
If you're missing the PZ1, you could just find a constant 12 volt and ground to power the seat.

From what I can tell, the PZ1 connector supplies power to the power seat, mirror and telescopic steering wheel memory, seat heaters, and seat climate control.
The only 2 wires you will need from that plug is the hot and the ground to power the seat for movement.

If your 2013 connectors don't match up, you could bypass the connecters and use something else, spade crimp on connectors, or whatever multi wire connector you can find.
The other small white connector P7 has the seat belt switch wiring.

I just went out to my 2014 with my DMM to confirm the following.
It is an SR5 with the power driver's seat.

This is the female PZ1 that should be under the driver's seat from the truck.


Looking at that plug as pictured above;
the lime green wire (top left) is constant 12volts, it would connect to a white wire from the seat.
the white with black stripe (top right) is your ground, it would connect to same white w/ black stripe

 

Wow. Super informative. Thx 1lowlife for all the info. I may have to pm you for more info if that's OK. I knew someone here would have a thorough reply thx again

 

I don't know much, but I'll be glad to help you if I can....
I'd say your biggest challenge would be to figure out the heater wiring, (HIgh, low, seat bottom and seat back) .
I used Rostra heaters so it was pretty simple..

I'm sure you can find some toyota switches that would fit into blank dash cut outs if you have any available..

 

You know more than me sir... Very much appreciated. TY

 

I am in the process of trying to hook up the airbag in my 2017 seats to work in my 2011 truck. Am I correct in thinking that the yellow/black airbag wire on the truck goes with blue wire on the seat and then solid yellow on the truck goes with brown on the seat? That's what I'm thinking but don't want to accidentally detonate the bag in my face if I hook it up backwards.

 

Bump.

having same problem at yotaholic

 

You ever figure it out? My truck has been at the dealership and I haven't had the chance to look at it in a couple months.

 

I used the same two wires to connect my Scheel man seat for cooling and heating. I de-pined and rewired the male connector (White, White black strip) to the scheel wiring only two cables were required from them. My original seats did not come with seat heaters. 2015 tundra
