Help with power seat wiring
Hi, I have power seats from an '02 is300 that I will be fitting into a different car, which has no power seat wiring in place (which I will be resolving by running a 30a fused link from an available place in my fuse box).
My question comes to supplying power to the seats..I feel I may be missing something obvious here. Through my reading/research so far, the 5 wire connector at the front of the seat seems to be what I'm after...the larger gauge white wire would be the 12v from the fused link, and the white/black would be the ground.
Correct so far?
Now if I understand correctly, the seat's ECU does all the work once supplied with 12v and ground...I'm testing the seats before I fit them (and need to adjust the sliders and height to have working room), but when I apply 12v to the white and ground the white/black, I get no activity from the switches for any function. I tried both seats as well, thinking maybe one had bad switches or ecu, but I get nothing from either seat. What am I missing here?
Also, looking over the wiring diagram, in addition to the ground in the connector, it also shows a white/black ground, that eventually turns into a brown wire, which looks like it feeds a junction box and distributes out that ground (assuming to the motors and memory module, etc)...but I don't physically see another white/black wire on the seat...only the one in the large front connector, that would normally plug into the wiring from the chassis...which I can trace that wire straight to the ECU. Am I missing this second ground source? I even used a grounding strap to link the seat frame directly to a battery ground to ensure a good ground. Still no dice.
Can I test the individual motors by just applying 12v and gnd to each lead on them?
Any help is appreciated, thank in advance!
