Bought 1997 Power Bucket Seats...

[quadracerx]

I bought the 1997 Silverado Cloth Power Seats to swap for the factory Bench Seat. I dont have the seats in my possession yet... Sometime this weekend!! The seller says the harness from the seat has three wires? Not sure why? Power, Ground... And?
Someone please enlighten me? Ill post a photo of the switches on the seat if that helps...
Thank you!!

For the lumbar adjustment, firms up the sides of the seat backs.

Ok... So the seat has an air bladder? Do you have any idea which wire is Positive, Negative and Air Bladder?

Easy to figure out with a test light. The bigger oval switch is the lumbar switch.

Do you have the service manuals, there free here, you'd have wire digrams .
