I just purchased my first MB a 1980 300CD. The cruise control does not work. So after reading a lot about resoldering the circuit board in the ampilfier I decided to attempt it. Well not knowing how to disconnect the plug that contains the wires leading into the amp. I ended up with all the wires disconnected and now do not know what order they go back in. Can you tell me what color wire goes to what numbered pin on the amp. I feel so stupid hahaha.
