I am trying to install a Dual radio with CD, my question is how do I interface the radios wiring into the OEM wiring? I know some one has a thread telling us how so can some one direct me to it? I am working on my wifes 190E 1991 mod. thanks for any help, JNT

trying to wire an aftermarket radio I found a diagram telling me what wires in the fader goes to what speakers, I have made the connections but have no sound from any of the speakers. can any one give me a hand with this?

hi every one, I finely got the center console up and traced the wires far enough back into the sheath and found the rear speaker wires, I the hooked up another radio (third one) and got the sound from the rear deck sounds great, still have to get another radio with CD for Miss Debbie. the two new radios are dual brand, wish I new how to fix them, manufacturer said sound board but cant find the damn receipt so on the bench they go.
