    Hello all, I just recently purchased a 1999 Mustang GT. The previous owner bought it and wasn’t running. Found out that the obd2 port was cut off and melted. He replaced it and now the mustang only runs with the scanner plugged in. However the dash periodically works and none of the lights work...

    So i am retrofitting the s550 style lights for my 2011. Originally they had a plug that replaced where the turn signal bulb plugged into. I'm wondering A) if it matters how i plug it in (don't think it matters) and B) which wires would be the parking lights and which is the turn signal leads...

    I am working on a newly acquired '64 Comet, with a 5.0 HO and AOD swapped in it. The car generally runs pretty well, but will pop (out the intake I believe) on occasion when applying very light throttle, and occasionally idle roughly. If it is idling roughly, it will likely pop with light...

    Hey everyone, new user here. First post. I have a 2017 GT and I'm trying to wire up some underglow lights for courtesy lighting. I already know how to wire them. I'm just going to wire them the way cjponyparts instructs you to wire the footwell lighting. That will make them only turn on when...

    I have a 68 Mustang that I've added a horn relay to. It did not originally have one, like most vintage mustangs. Since I modified my steering wheel I had to create my own horn button and because of that, wanted to ensure I did not fry it running full voltage through it. So, I decided to add a...

    Calling all gurus. I have just finished up putting a 302 in my coupe and I'm having an issue starting it. The current situation is that when I turn the key to start all it will do is turn over and over and backfire through the carb. I already fixed an earlier ground issue, I am positive that...

    Hello everyone, I am coming close to finishing the whole I6 and V8 swap. This weekend I finished the wiring of the engine and its components and attempted to fire up the engine. When I attempted to do so, the ground from the engine blew and the solenoid did as well. After replacing the...

    Hi, this is my first post and I'm stuck in a real pickle. I just replaced the bushings on the drivers side door hinges because they went bad. all we did was remove the door and move it a few inches so we could get to hard to reach nuts. To remove the bottom hinge, we took off the drivers side...
