Thanks for the nods on the build. I've put a lot of effort into it
I haven't read the big three thread on this page but I will tell you grounding the engine to the frame with a $4.00 per foot cable is a waste of your money. Look at the battery and start from there. It's no so confusing
3 wires on the negative terminal. One to body, one to Frame, and one to engine block. The positive cables go to alt, to system, to fuse block, to starter. Just worry about the one running to the alternator here.
This picture displays the cables I made to replace the factory ground setup for the battery
If you look back at the top picture you can clearly see a positive wire running over to the alternator from the battery. That's as simple as it gets.
This is where I grounded from the alternator
That cable runs to here
The ground from the battery to the frame grounds here as well, as instructed by Irragi. I bought a 1/4" 20tpi tap and got a stainless steal bolt to secure this after I got the frame nice and shiny with a wire wheel. The location is pretty much in the center of the frame right below the two fans.
That's all you need to worry about doing the big three.
I was being an asshole last night when I originally posted this so I changed it to make me look like a nice guy.
