Once again I tried to replace the Becker Europa in my car with a basic CD/iPod player. This time I went to the 'experts' at Crutchfield. They sold me the wiring harness and everything. I asked specifically would I need anything more or need to do anything odd. No.

Well, going to hook it in today and apparently I need a constant power source, they suggested hooking it up to the ignition wiring. I have no idea how to do all that. Is there any easier way?

I'm not much good at this stuff, but I hate to go pay Best Buy $300 for what should be a simple job.
