1993 Cadillac Seville deck install

I have a 1993 Cadillac Seville and I need help installing an aftermarket receiver. I bought a wiring harness for the car but it doesn't seem to fit the oem harness behind the factory deck or the cdm harness in the trunk behind the power antenna. I used a 32 pin Gm harness but I can't figure this out. If anyone has any ideas on how to install in this car please reply.

Take the aftermaket harness back and check to see if it is the right one, or if they have another for it. Take a look at the others that they have, see if any look the same as what you have in your car. Maybe you have a Bose system and the harness is for non-bose, or vice versa.You'd better get me out of this lord... or else you'll have me to deal with. -- Hunter S. Thompson "F.A.L.I.L.V."

Or even better, try to have the car at the store with the headunit out so you can try it right there, and if it doesn't plug in just bring it right back in.You'd better get me out of this lord... or else you'll have me to deal with. -- Hunter S. Thompson "F.A.L.I.L.V."
