I have an 89 gt convertable with every electrical problem you can get. The car now has a newer, cleaner harness but still major ploblems. I live in Cincinnati, Oh looking for a shop or someone with knoledge to assist me fix this problems. the car cranks but will not start, the lights work but when the hazards come on the whole car surges, power locks and windows don't work, can't start the car with the key
