Okay, so I'm actuallya Ford guy, but I need some help from the experts. I put 2004 Tahoe seats in my 1983 Bronco.They are power everything and leather. I hooked them up and got power to everything that moves, which is 8-way. I was hoping the seats would also be heated, but I can't tell by looking at them. Is there a way to identify a heated seat by looking underneath? Does anyone have a wiring diagram to help identify which wires control the heat? As I have it now, one power wire and one ground power up eveything and there are about 6 more wires in the plug. I tried giving each one of these power, but nothing happened. Any help would be appreciated.

 

Welcome to the Tahoe forum. Might try doing a continuity check to see there is one pair of wires with a low resistance. Also since the seat backs also have heaters, might check to see if any wires come up out of the base to the back.
