Wow, I have to say that was totally easy! I went from the unit on my desk at 12:15 pm:
To having it completely installed and charging by 2:00pm:
Basically, when the PO added the battery charger to the univolt, he basically attached the positive and ground wires to the back posts, right behind the fuse panel. I took these off, when down to the depot and got 4 feet of 12-2 wire (the instructions stated that the rating was for 12 to 2 gauge wire). I attached one end to the positive, one end to the negative/ground from behind the fuse panel, and ran it to the connection on the intellipower unit. Added the additional ground wire, and that was it!
