I have an old optimus cd player and I don't know how to hook it up in my car....?

Question

There are 8 wires connected to it. Umm...thats all I really know.

Answer 1

The wires should be color coded, so finding an ops manual or, since these codes are largely international (but not always!), a trip to a car audio installer will be happy to help. but for a price.

Another way, knowing the country of origin will help, and the codes can be found somewhere.
