Installing Lexus Is300 Power Heated Seats In Older Vehicle

[claysimo]

I have been searching everywhere to find some information about wiring these Lexus IS300 seats. I am putting them into an older vehicle and will have to be creating the wiring from scratch.

I have no need for the seat belt sensor, seat air bags, or the memory functions. There are 10 wires on one harness and 2 wires on another harness leaving the drivers seat that go to the car. so far I have identified that the two wires on the second harness (yellow-red, yellow-grn) are for the airbags. The 10 wires coming out of the other harness include a larger white-black and larger blue-white wire, and smaller brown, black-red, black-blue, white-green, blue-yellow, blue-orange, white-red, black-yellow wires. The black-yellow appears to be the wire going to the seat heater buttons. Does anyone have any clue how I could wire these to get the seat power working??
