Converting Manual Cloth Seats to Power Leather Seats (HELP)

[TxHummer07]

So I found a deal too good to pass up, my factory cloth seats are worn and the stitching came loose on the drivers seat and since then I've been losing the molded foam out of the seat. A local junk yard just got a wrecked H3 in yesterday and I'll be getting the leather power seats out of it.

Has anyone ever converted from cloth to power? I'm guessing, since I have cloth there isn't a power connector just sitting there waiting to be connected?

Anyone have advice or have done this before, want to know if I'm getting in over my head. I can hardwire/direct wire if not, but would prefer a factory plug. Thanks!

There might be the wiring for it already, in all of the schematics I've seen it looks like they just used the one harness, since the driver side is power adjustable anyway. Not sure if they'd have done the same with the passenger side. Unless someone else knows for sure, I'd say get under your seats and check what is already there in your vehicle, take pictures and whatnot, and then go compare it to the salvage H3 you're going to pull the seats from. I'd say worst case you pull as much of the harness as possible from the salvage 3 and use that to rewire yours.

Yeah, that's very true! I planned on taking the harness from the floor of the wrecked h3 regardless. Thanks!

You should also check for the necessary relay and fuse; they're listed in the owner's manual. BTW, cloth-covered seats could have the power option.

Okay thanks! I didn't know the cloth seats came power option in 06-07 h3's.

I've done it. Wiring isn't there. There are spaces in the fuse block, but no wires on the connectors. I added the terminals to the fuse block connectors and ran the wires into the cab using the extra wires that would normally be used for the optional lighting. Then made an interior harness with GM connectors. Takes some good studying of the wiring diagrams but isn't too bad. All of the parts are available from your local dealer so you don't have to cut into anything. You need RAP, constant hot, ground, maybe another wire or two. It's been a while.

Sweet! Thanks, I have a starting point haha. Something to do on the next long weekend off from work. Although I checked on lunch and I have open connectors under the seat...so maybe I got lucky and it had leather at one point before me...Either way thank you!!
