Hi All, I searched but was unable to find a thread describing my Comand connection. If there is one, I would appreciate being point there.

In trying to replace my Comand head unit, I pulled it out expecting a fairly large wiring harness only to find the two fiber optic cables and three other wires - brown, red/yellow, and a blue wire. This seems over simplistic so I am wondering if there is another harness somewhere else this feeds into or if someone can point me to a harness adapter I can use for an aftermarket stereo. I have a fiber converter from an android unit I had in a GL that was totalled so I understand I will need that to move to an aftermarket head unit.

Thanks!
