2003 Mustang Power Lumbar Wiring Issue

[drdino]

The more I talk to the Ford dealership service and parts departments in my area; the more convinced I am that they are useless. They cannot tell me what part(s) I need to buy to energize my power lumbar support.

I replaced my driver's side (6-way) power seat w/o lumbar support with a seat w/lumbar support from a 2004 Mustang. I was able to use my 2003 power seat track. Problem is there is no power connection for the air pump (located in the seat bottom side - inboard side) or the rocker switch (seat - outboard side) for the lumbar support (the rocker switch does have a connector that needs to be plugged in). The only power connection I have comes from under the carpet and plugs directly into the connector on the track. There are no other empty (available) connectors.

I am assuming it is an air pump in the seat as there are air hoses running to the one end and what appears to be an electric connection (location) at the other.

The dealership service and parts departments cannot tell me if I need a new seat track or if a wiring harness is available or if another remedy is needed.

All help will be greatly appreciated. THANK YOU!!!

Is this what your plug looks like?

I'm fairly certain it plugs into another plug on the power seat track.

I picked up another set of seats from an '04 GT to put in my 5.0 Mustang and this is the plug for the power lumber.

I was going to pull the seat ouyt of my '03 GT this weekend to take a peek at where it plugged it, so i'll let you know. But my '03 only has one plug coming from the seat, so that lumber plug def needs to go to something on the seat track harness

It looks like that. There is no place on the frame to plug it in. I have taken the seat out and closely looked for any empty connection but cannot find one.

I pulled my '03 GT's power seat out to take a peek and vacuum the rug underneath.

The power lumb plug definitely connects to a harness or plug on the power seat tracks. There is only one plug feeding to the body.

However, the plug is tucked up somewhere near the lumbar switch and without taking the power seats tracks off (which i really don't want to do) i can't see where exactly it plugs in.

But it def goes somewhere on the track

Thanks for your reply. I did, however, separate the seat from the track and could not find anyplace to plug it in. My track must not have the plug in as it was not equipped with a power lumbar to begin with.

Thanks again.

It just needs a 12v + and a ground connection for it to work. So you can maybe splice it into the main harness with some testing of the wiring for a ground and powered 12V
