Adding relays

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.

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.

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

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.
