my friend owns a 1987 Town Car. It has a factory JBL system in it. I suppose that was the premium sound for that c ar. And I tried to install a head unit in it. I have experience with putting head units in but this one gave me trouble. I did some searching and It says I need OEM connectors? Im unsure what this is all about. But if any1 can help me out finding a way to get this headunit workin in the car. I would appriciate it greatly. Thanks.
