1/0 wire from alt to positive battery terminal.
Ground from the chasis to the engine block.
Other end of the alt to the battery, the blue wire goes to the rear and splits into two 4 gauge wires that lead to the amp. You have to excuse the bootleg setup there, due to the fact that there is so much crap connected to the positive, I could not put a fancy stinger terminal up there.
Chasis to negative battery terminal. I left the stock negative on as well since it was connected in two places...(weird nissans)
EDIT: Screw was to long so I moved that ground.
Again, the new negative from the battery to chasis. Notice the battery connection, dont let your wires slip!!!!
Tied the 1/0 wire off, dont need any mishaps!
This is the stuff I used when i sanded down the area for new connections, got it at a parts store Pep boys I think.
And there you have it, The Big 3. I havent checked my voltage yet, but when I do I will post it.
