Nice and clean, good jobStarted the wiring for the fans. Mounted the relays close to the fans and to hide the wiring it goes thru a grommet into the fender where I'm running the headlight wiring also, all thru a plastic tube.

Good question, a lot of people ask that. Leaving it and using it as in the pic helps reduce the load on that circuit, without it the black under dash wire by itself could get overloaded and get hot. Also it is easier to leave it and it's fusible link, less work. And if anyone in the future wants to put it back stock everything is there and easily put back as it was.. I simplified it even more by spicing the black to the red under the dash right before the firewall connector, and left the red wire as is going thru the connector since it isn't prone to fail like the black from alternator. And I did as the info recommends and soldered the splices, making less chance for failure.So, I understand and like the idea of bypassing the factory ammeter and eliminating the firewall terminals. But why would you keep that red wire in there? It seems unnecessary and introduces two extra potential points for failure (splices).
Good ideas all, but make sure you waterproof the breaker if it's under the hood. That's why they had fusible links out there, they're waterproof.. Also, you can put a voltmeter in place of the ammeter to keep nearer to stock.I installed a 100 amp alternator and added a #6 wire from the alternator to starter relay with a 12 gauge. fusible link. Im going to eliminate the fusible link and use a 80 amp DC circuit. breaker in its place. I left the black wire in its. place and spliced in a 30 amp maxi fuse. Black and red wire wires are hard wired going. through firewall junction box, so it looks original. The amp meter is also bypassed
It will save a lot of money to build your exhaust system yourself.Should be fun welding it up.
