Lexus Power seats
I am looking for some information on wiring up some bucket seats we picked up from a Lexus RX 20xx.
There is a cannon plug with 5 wires in it two large gauge and 3 smaller gauge. The 2 large wires power the + and - to the switches and they all work! We are at a loss what the other 3 smaller wires are for or for that matter what they power, does it have a seat warmer if so how do I tell ??

I think power seats would be fairly heavy gauge 'cause they would be drawing a few amps.
Could the lighter leads be for the airbag activation circuitry? The newer stuff 'knows' if there is nobody in the seat by some kind of pressure switch in the seat.

I've found in general the extra wires are for seatbelt warnings and airbag triggers. Seatwarmers in the ones I've used all relied on the same 12V+ as the seat motors did.

Let's move this to the Electrical forum.
