Well, i checked the plug in the back ,and i doubt anyone touched that unless someone from msd did. Its screwed in .

Plus if it was on 4 or 6 cyl wouldnt it run like crap? My warranty is up,even though this box has only been in the car for a few weeks. I had it rebuilt by msd and put it on the shelf as a spare,but its been sitting for over a year unused..

Guess a new box is cheaper then rebuilding a motor!
