does it have to be on the engine? and the third part of the big 3 engine block to chassis...the stock wiring has two wires to the negative, one to ground and one the engine block..im still confused on the last part of the big 3so if that one engine bolt is a PITA why not search for an open threaded hole on the block?
theres tons of other bolts on the engine but they all wont move lol. and they have the engine to negative, but the last part of the big 3 doesnt say that...so do i just do the engine to negative AND ground to negative like the stock wire was?Its upgrading your stock ground is all. So yes it has to be on the engine. If that bolt ain't nudging then look at like a valve cover bolt.
really not trying to sound like a d-bag here but did you peep the big 3 thread??? there is plenty of pics in there bruhi dont have the proper tools to do it so easily
