Battery Negative/Ground Cable Upgrade

@prone2xl Any updates on your compression lug or the performance?

I installed the same @SDHQ OFFROAD terminals yesterday and I had the same issue, about 2 threads showing on the fitting. The instructions say tighten until “snug” so that’s what snug was for me.

 

Our battery terminal cables are 2 gauge wires correct?

 

If they are like 1st gen, the positive is near a 2 gauge and the negative is between 2 and 4 gauge. The metric next-closest size to 2 gauge is 35^2 mm from what I've seen and it appears that's what these OEM positive cables are. That's why I sell this to upgrade the engine ground to 2 gauge and the chassis ground to 6 gauge: https://www.dcmachinist.com/product...true&sa=false&sbp=false&q=false&category_id=6

 

Resurrecting a old post, those that did the big 3, where did you run the ground from engine to frame? I was hoping I could use the bolt that holdes the harness against the alternator, I know that part is plastic, but I want to the terminal behind it that way it's on metal. And ground it to the frame just below it.

Plus in the last photo, there's 2 bolt holes just below my little fuse holder, what is intended to go there? I was just gonna tap my new battery ground to it

Steammynutz, the two bolts in your last pic are what holds the clutch fluid reservoir, or at least that's what my 2018 has there. While I haven't done the big 3, I'd think any good engine point would work.

 

Ahh, gotcha. Makes since being mines a auto. I did end up running my bigger ground to the 1st bolt hole, I'll also be using the alternator mounting bolt to the body bolt in my 2nd photo for the ground. It's a slow process being its been 90-105° out. And I for one am not a summer heat fan.
