I'm trying to install a basically new Pioneer stereo in my 93 Fleetwood. I ordered what I thought was the right wiring harness adapter, only to find out it wasn't. I tried every local parts/automotive store, even walmart. No one has the right harness. Only one I can find for 93 cadillac fits apparently every model but the Fleetwood. It's a single plug while the one coming out of my dash has two different plugs with no antennae wire. Anyone run into this problem?
