I just cheaped out and bought an Alpine CDE-7859 Headunit off of ebay. It seems to be in good condition, but when it came in the mail, there wasn't any type of wiring harness to go with it. Is there somewhere I can go to get the harness, or do I just need to get the wiring adapter to match my car make? If you guys care, its for a '89 Nissan 240... Sorry, it's been awhile since I've dealt with car audio, lol!
