Shit I did 2 of the big 3 already. Im just missing the alt to pos of batt. But the godam alt is so hidden i cant reach it. I might just take it to a shop and have them do it for. Take the alt out and then put the wire on it. Im guesing this wire is the one that helps out the most. LOL and i dont have it.

wtf is the big 3?

The main wire from back of alternator that goes to + battery.

The - wire from battery to body of car

The - wire "strap" from body to engine block

These are the big 3 and should be upgraded to at least a 4 gauge wire
