Big 3 2005 Yukon

[99blazer]

the enginge ground was the easiest one cause all you gotta do is ground it to the alternator bracket. on some of the gmcs and chevys ive seen they have 3 grounds one on the engine one on the fram which mine was a pain and one on the body which most likely be the worst factory ground. but the way I did mine was just positive to alt and on ground which probably not right to some ppl but works for me is negative to frame then frame to engine then another negative to chasis. but doing the big 3 with a stock alt isn't going to make a huge huge difference but it does help some.
