I got my GTA seats all wired up and mounted in the car. The passenger seat works perfect both lumbar and bolster. The driver lumber works as it should however the bolsters aren't moving at all. Come to find out I'm missing the air hose that inflates those bags. Can anybody tell me how that hose is supposed to be hooked up?

 

Could you please explain the wiring you did. I have a set very similiar to yours and I'm going to put them in an 84 that has no power seats so I'm starting from scratch. Each seat has a 6 prong plug. My guess is each seat gets a power and ground at the orange and black. Then do you just match the colors from seat to seat to power the lumbar stuff? Mine have air tubes with plugs on each seat. I'm guessing I need some lines that attach these together.

 

well as far as wiring goes i didn't do any really. Mine was basically all plug and play since i was lucky enough to find the factory seat wiring that operates both seats. Then all that was left was the orange and black wire. I grounded the black wire and i found a connector under my dash to hook up the orange wire to and that was it, working seats.

I'm still stumped on the hose routing though. I still need to find out where those bolster hoses are supposed to go.

 

I would think the hoses just plug together. The air pump is under the passenger seat only and the airlines from the pass seat must just plug into the airlines from the driver seat with a hose extension (with the proper fittings of course). The rest of the electrical wires in the harnass must control the pass seat airpump from the drivers seat controls.

 

You are correct in the fact that the driver seat is the one with the air pump for both seats, and yes just one hose goes over to the passenger seat to supply air for the lumbar and bolster. However on the passenger seat i have 2 hoses running up to the seat back, one for the bolster and one for the lumbar. On my driver seat I only have one hose which is going to the lumbar since that one still works. I'm missing the other hose for the bolster which would then connect to the bottom of the seat where i have an open port for that line.

The big mistery to me is how that line is connected to the bolster air bags?
