http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=50556&item=5712202256&rd=1 My 04 GT has the 6 disc changer headunit. I was wondering if this mp3 unit will plug in to the existing harness, or will it require a lot of wiring to get it to work. If not can you suggest a factory mp3 player that I can use. Thanks
You can't use that as it's a totally different shape, along with totally different wiring. The newer Mustangs come with MP3 capable head units, so pick one of those off ebay instead. Also, you have to get a 01+ Mustang radio or it won't bolt in.
