winterset Posted September 27, 2010 Report Share Posted September 27, 2010 I don't have any extra plug under there. I only have standard seat controls, and power recline on both seats. Do you have Memory? If you don't have a switch for heet, I don't believe it's for that. Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 27, 2010 Report Share Posted September 27, 2010 I had those plugs on my 96 and assumed the car was wired for memory seats as it is sometimes pre-wired for a trunk mounted CD player Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
rockfangd Posted September 28, 2010 Author Report Share Posted September 28, 2010 base model deville with power recliners. Doesnt have memory seats but working on it. It is not prewired for memory seats (i believe because when I replaced the switch pod in the driver side door and added the memory switch there is no plug for it). no switch for heated seats. Maybe I can get a pic. It comes from the floor and not the seat If that helps. My eldorado had heated, lumbar, and memory and the olug was used, but for what I dont know. The only model cadillacs that were wired for cd cchanger were the ones that had the CD button or the source button shown on the stereo. Both with subsystem or without subsystem , but all with the subsystem were wired for changer GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
