Seat Wiring Diagram

[mojo_jojo77777]

Anyone happen to have wiring diagram for our cars?
Bought extra seat of seats for my E90, and trying to figure out the repinning since my LCI model is bit funky from other wiring I've found for that chassis.
I think I might have most of it figured out, I think biggest issue is figuring out CAN High and CAN Low. and seems our seats have 1 ground instead of 2 like my E90

can't offer a diagram but CAN wires are usually green and green with stripe, the striped wire being CAN high. see anything like that under there?

So on my E90, CAN wires are indeed green and green/yellow stripe.

But on Supra seat (I even confirmed on my own chassis), I see:
1 thick red/yellow - I'm assuming positive power
1 thick brown - I'm assuming ground
1 medium red - maybe power for lumbar
1 small brown
1 small red
1 small blue

I'm maybe thinking red and blue could be CAN wires. but they arent twisted together, but are pinned right next to each other.

yea from what you're seeing my money's on red and blue. have any backprobes? see what voltage reading you get from the 2 with the key on pos 2. adding the voltage up should be at or very near 5v.

CAN is yellow/black and yellow/white and a twisted pair, when located in the passenger footwell. Might be different under the seat as it's a different CAN network.

Hi Mojo_jojo,
I saw your post on the Supra seat wiring a couple of years ago. Did you ever figure out how to get all the wiring hooked up to make the power seat functions work? Like you, I am trying to install the GR Supra seats into a different vehicle and I can't figure out the wiring to get the power functions on the drivers seat to work. Any help from your efforts would be greatly appreciated.
