mainly a 76 jeep cherokee.

i just installed a set of these in my cherokee.the pass side was a snap just 2 wires for the motors and 2 for the heaters.the driver side has a memory control box under it i guess to remember different driver positions and i think it even controls the pedal and steering wheel and mirror positions.all of the motors work because if i power them directly they run fine.the plug on this side has about 8 or 10 wires going to it.2 wires are big in dia and the same color as the ones from the pass side.i tried powering one and grounding the other(just like the pass side)but got nothing.i have no idea of the model or year of the car which they came from.
the memory switch on the side of the driver seat has 2 positions.i tried wiring the seat belt wires together thinking that it may have to be connected.all i want is to get the position switches to work im not at all concerned about the memory.does anyone have a wiring diagram for the plug?
thanks
any help is greatly appreciated

the guy i got them from said they are prolly from a 93 es300



stupid question here but do i have to be sitting in the seat to test it?does it have to sense weight?the pass sid didnt matter.

I'm not sure without an EWD in front of me but there should be an ECU somewhere that is imperative to the seat memory/driver power seat function. The newer lexus vehicles have a dedicated ecu in the drivers side door that works for the power mirrors/windows and seat memory. Gimme some time to check a electronic wiring diagram at work. GOod luck, sounds like a fun project.

Real quick, you do not have to be in the seat for it to function. In newer lexus vehicles they use an occupancy detection system only to function in conjunction with the passenger side air bag system. It should work with you in/out of it.

i finally got them to work.if you switch the 2 big wires on the pass side the seats just move opposite of what they should but if they are switched on the driver side they wont move at all.i guess the computer also feed off of the power wire so you cant switch them.they are installed and working fine now.thanks for the help.
