I have a 1990 F-250 custom and I have a random cord behind my seat that looks like it goes into the driver side wall near the seat belt does anyone know where it plugs in or way or does? It's attached with white snaps to the wall.

 

A picture would certainly help us identify it.

 

 

the pic doesnt work on my computer but it sounds like the cord for the lumbar support. yours might not have it though as it was an xlt option. if you do you will have a switch with a plus and minus sign on the side of the seat and an air pump in the seat

 

Pic doesn't work for me either.

 

While this could.be possible since my grandpa replaced the original seat before mytime. But why woukdnit have lumbar support if it rodent have elective windows/AC or 4x4? Is it possible it could be my cab light outside?

 

cause lumbar support was a fancy option and a request only thing. the truck that has it was orignially my great grandpa's fancy truck so it has chrome everything and every option avaliable
