I also ran a 6 gauge wire from the alternator to the battery and connected the other main system feed wires to it with a large crimp terminal in the stock junction location over behind the driver side headlight.

Really like your setup! Was thinking of doing something similar. Also I want to upgrade my alternator to a 12si then wire 6 gauge to the battery just like you did. I typically do that in my ford just learning the chevy ways.

Re: Adding relays

The more I am getting into this truck the more I am wanting to buy a new harness. A additional question. Both of these circuit breakers(?) are unhooked. Do I need to do anything about them? Someone has really been in here with a lot of taps and added cruft.

Re: Adding relays

That relay near your fuse panel is you horn relay. I'm not sure what the other relay is.

Re: Adding relays

The other one on the firewall is for a spark delay. No need for this any more. It's useless you are going totally stock.

I added my fan relay between the battery box and the core support. Almost invisible there at least no one seems to find it unless I point it out.
