Get yourself a multi-meter from Radio Shack and it should be easy to figure out. You are looking for continuity between any 2 of the contacts that is switchable. You do not hook "ground" up to the switch unless there is an indicator light in it *usually*. Go to www.motorbooks.com or 800-826-6600. They can help you get a book on car electrical wiring. It is a little more complicated than what you are doing. You need to get a good source of power and it is important to protect (fuse) it for safety. You also should use the correct type and size of wire. Learn more about it, it is an interesting subject. I would let the antennae go up and down, that way you can switch quickly between the radio and the C/D without waiting for the antennae to go up and down. --- In dmcnews@xxxxxxxxxxxxxxx, Tom Watkins <dmctom@xxxx> wrote: > I have a question for anyone who has bought these from DMCH.
