I pulled my father's seats out the other week to clean and install an amp and I had the passenger side seat upside down. On the bottom there was a wire harness coming from the rear of the seat cushion that said heated seat or something to that affect. It's plugged in to the harness coming from the floor. I installed the heated seat control from my car but didn't get the light to come on, did any cloth impala come with heated seats? Also realized I was missing the green wire on the hvac harness so I'd have to add it. Is there anything else I need?
