there seems to be a short somewhere. When we first tried it it worked fine when you went from 1st to second the light would come on and the same when you went from second to 3rd the corresponding light would light up indicating you were in 3rd gear. I wanted to bypass it to confirm that the car is indeed going through all 3 gears should this problem ever occur again and be able to know that if necessary we could shift it manually. When you hook 12V to it do you also have hook a ground to the other prong next to it and does it matter which one you plug it into on the connection on the trans?
