If that's my biggest problem, I'll take it!
They're 1/0. I guess the one that goes from the cut off to the factory starter relay could be smaller, but I didn't know. I have some 4 ga. If that's big enough, I could swap it to save some weight.
I should have some time to work on it tomorrow. I reeeeally appreciate your help.
Electric is my Achilles Heel, for sure.
