Hooking up the positive an negative can be daunting if you haven't done electrical stuff on your car, but even if you haven't all you do is attach a spade end on the cable and slide it right into one of the open slots on the fues box. The screw on the upper left hand side of the fuse box is a ground so that is pretty easy too.
The hardest part for me was drilling the dang hole in the pipe. Looked like the preverbial monkey humping a football since I didn't have a vice to hold it.
It is a very easy install. 1-1.5 hours total, and I could screw up anything if you give me a wrench.
