The power antenna on my 1983 300CD has been replaced by a replacement Hirschmann antenna which has a plastic "plug in adaptor" for the 12 volt power source and signal from the radio. I would like to replace this antenna with an original Hirschmann antenna from a 1984 300D with the mounting bracket from the 300CD. My problem is the wiring - the colors of the wires do not match up with the wiring loom in the car. I have hooked up the wires according to the numbers on the loom, but no luck. I know that my replacement antenna works fine as I hooked it up to my 1985 300D and it worked fine.
Does anyone know the proper way to wire this antenna? I dno know that I have two hot wires from the loom (red and blue wires). Thanks.
