This style of voltage regulator always needed an excellent ground or it would overcharge. I'm not sure huge wire is needed. The video recommends connecting the VR and the alternator casing, he said nothing about hooking a 4 gauge wire between the two. Did you talk with the guy?
I'm a ways away from actually trying it out. Don't think I need the whole Kit with plug and play harness.
I personally think that 4AWG is overkill, I was thinking 8 or 10AWG. I'm sure Mex would know better than me. The regulator case ground is not carrying the full alternator load. I have no idea how much load and voltage drop are acceptable.
This is also a project that is on the back burner for me. Every time I take out the factory manual and start tracking down wires I get pissed off because whoever drew the schematics broke down all of the systems to a page or two. The problem is that when a wire is common to two circuits it is difficult to follow the current path. Its like trying to see the big picture through a microscope.
I was hoping that I could find someone that has done this. I didn't want to be the guinea pig and let all of the magic smoke out of my PCM. My PCM cost $200, so its not the end of the world. I am going to check a few things Mex recommend, then I might replace the PCM. I would like it to work stock but I am starting to think that the stock design sucks.
