I recently purchased a 94 Deville Concours. The radio in it, a Delco-Bose Active Audio, model #16163906 was not hooked up. The original harnesses have been cut. I have only the individual wires. I found some radio wiring diagrams for most cadillacs but the colors do not match this system. I believe this is the correct unit for the car because it is a remote unit, and there is a reciever in the trunk. There is also an amp in the trunk.
So far, I've only been able to figure out that there are 3 hot wires comming from the car, 1 red/white, 1 orange, 1 yellow, and 1 black ground. I have no idea where to connect these to the head unit. Also there is a dark green wire on the head unit, that lights up the unit whenever I connect any of the hot wires to it, but it doesn't respond to any on/off, tape/cd functions simply with this connection. I did hook up a spare aftermarket radio and got it to turn on, but no sound came out trying to connect the speaker wires to the remaining wires coming from the car. I guess that was beacuse I didn't activate the amp. I really want to use the factory head unit that came with the car.
I guess I need a wiring or pinout diagram for this head unit, and for the wires coming from the car. Can anyone help please. The car is nice but some sounds while driving would be great. Can anyone provide some guidance or diagrams?
