Finally built some battery cables today. I finally believe I am done with running grounds. I have a 2 gauge to the block, a 6 gauge to the frame rail, a 6 gauge to the header panel, and a 4 gauge from the intake to the firewall. I have also added the extra ground to the blower motor, an extra under the dash, one at the fuel pump, and a real one at the tail lights. I am about due for another tube of Oxguard.
I really like the military style battery terminals!
