To be clear, I have the door harnesses themselves - I don't have anything to plug them into on my existing wiring harness. My friend "Mustang Josh" pointed out a harness which can be bought on ebay for adding power windows/locks to the 87+ Fox Body's but looking to find information on if the same harness will work on an 1983 EFI Turbo Car. If not does anyone have information on the harness which will work?
