Added power seats Posted by adam [Email] ![]() ![]() |
I got a great deal on a all 4 seats from a '96 Aero a while back, and wanted to put them in my '92 9k for something to do. The rear seats bolted straight in with no issues at all. The passengers seat bolted up, the seat heater plug was the same, but the plug for the power seats was missing one power wire. The 3-wire plug on the seat has one large red wire that goes to a 30A electric seat fuse, a large black ground wire, then a small red wire in between the two. The 3-wire plug in my car (withouth power seats) had the large red and large black, but an empty slot in the middle for the small red wire.
I found out that the small red wire was the feed to activate the two relays on the underside of the seat, and was necessary to operate the seat.
Instead of hacking up the wiring in the car and running a new power wire, I flipped the seat upside down, cut away about 1/2" of insulation on the large and small red wires, soldered the two together, and electrical taped it back up. Now, the small red is fed from the large red (fed through the 30A fuse) and the power on the seats works great! It plugs straight into the existing car wiring with no modifications to the car except for adding the 30A fuse. Even the seatbelt latch was the same.
For the drivers seat (which I haven't done yet), I'm going to take the base from another power seat I have, and switch it over to the Aero seat base to get rid of the memory (the fella I bought the seats from wanted to keep the memory computer). I still have the regular manual cloth drivers seat in, and will finish that off soon, but I wanted to let everyone know how simple it was to add power seats this way.
