I have a 1987 Ford LTD Crown Victoria with the Premium sound package. I went to the local audio shop and they don't know what wiring harness I should use. It says for 1983-89 Crown Victoria or 1990-91 LTD Crown Victoria so it leaves mine out. Any advice?
They are correct. You cannot simply hook up a vehicle participant to a wall socket. Car avid gamers use DC electrical energy. Your wall offers AC electrical energy. If you hook it immediately up your CD participant will probably be performed for, and would possibly trap on hearth or explode.
Get a wiring harness from the internet. There are tons out there and it will probably be cheaper than buying one from a store. If you don't know how to wire it yourself make sure you have a shop do it unless you can find a wiring diagram. Another solution is that some shops can use the wires that already come from the back of the radio and wire it into a jimmy rigged wiring harness. It would work just a well, but you have to know what you're doing to make it work. I would stay away from those wireless radio transmitters. They are buggy and not worth it. Worst case scenario, upgrade your head unit. You can get decent ones for a few hundred bucks or less, and it would be way easier to hook up auxilliary sources.
