NEED HELP Passenger Seat RV Mirror Wiring Info/Help

[AC75TB07]

Hi,

Under the passenger seat in my 2007 LT is a bunch of wires that clip just below the front of the seat cushion. When I bought this truck they had come unclipped and a couple were cut or broken. I just taped them up as they were because I had no clue what they controlled and the seat itself did and still does work just fine.

Anyway, the light for the passenger airbag on the dash is always illuminated and the little airbag indicator in the rearview mirror is on and off or flickering... From what I can figure out the wires under the seat impact this stuff... So, can anyone help with the underseat wiring? What colour wires do what?

IIRC there was a green wire totally broken and perhaps a yellow one that was holding by just a couple threads....

Thanks

I do have the service manuals but looking at wiring diagrams is a bit like reading in the car... makes you puke... I've been through them a couple times but can't find what I know is in there somewhere...

I previously HAD a page of the diagrams that showed the underseat wiring and the links to the RV mirror, but finding it again is making me cross eyed... #FML
