I have recently bought a dis 4 box. I'm the second owner and the harnees came already wired. The guy I bought it from had a 3.4, mine is a 3.8. The question I have is the #2 interface doesnt seem to be passing any fire thus the missfiring. I took the tape off to see if every thing was hooked up right. I also used this diagram for help. http://www.angelfire.com/ok5/tiago/MSD.html
It looked right and I used a meter to see if current would pass and it did. How can I find out if its bad? Or any help fixing it would be appreciated. One other question: the red and black wires coming out of the box, I grounded the black and touched the red one to my posi side of the bat and the light doesnt turn on. Is that how is suppose to be wired???
