So have it like this? http://i232.photobucket.com/albums/ee30/mblouir/Frame.jpg with the blue wire going to battery negative? I'm just cautious because that would be the engine ground also goes through the frame ground wire, which would be fine right? Hmm not sure how to ground to the frame lol. It's in the back of my extended cab truck. What's the longest the amp ground should be? 1 foot? Also my truck has extremely low kms and the original owner had the whole underside of the frame/truck sprayed with that black tar stuff, I'd have to sand a spot of it off I'm guessing to get a proper ground to the frame.
