I recently converted over my 88 mustang to mass air and put in a 93 computer. I also put a supercharger on it and ever since I did that when I turn my lights on my fuel pump will come on with the key off and my gauge cluster will go crazy when I turn my headlights on. Has anyone had this problem or know what it is? I also got the car painted and checked all the grounds to make sure they weren't covered up. Any help would be appreciated.

you might still have some grounds off under the dash? or somewhere still in the wiring, i just went through the same problem!
