Hey guys well my name is kris I own a 91 mustang which has the 5.0 of course. My question for you guys is I have been having electrical issues with my car ever since I have owned it these past 4-5 yrs. I took it to a guy to get it running which he did but I have been with out most of my electrical components.... windshield wiper, horn, cruise control, door locks, rear brake lights...etc. Although my windows do work. My main question here is am I just better off just buying a whole new wiring kit and starting from scratch. I don't have a/c it also runs really rich and I just dont want to put a/c in my car just yet till I get it all perfect and figured out. I also live in south florida so I am dying without some good old a/c.

I appreciate any input
Thanks
Kris
