Sometimes you just gotta work backwards.....knowing black is always ground UNLESS It has a stripe, then sometimes it is power (thanks ford).
Knowing the larger wires are power circuits, this stuff really helps
the stock seats use a 30 amp power feed for the switches and motors and a separate power feed for the heaters. On my BII I used a 40 amp mega fuse and ran one power wire to both seats, grounding the seat heaters right there at the base of the seats. The factory 1988 power feeds for the air lumbars are still in place, they just provide power for the power seat motors.....
