You need to have healthy wiring with the proper ga wire for each load. When I installed the later model mopar charging system (from 30a to 74a) I installed a 4 ga wire from the alt to the starter relay. The bulk head connector was always my fear until I did away with it completely... its there but has the wires push straight through... no connectors. As well as the "Amp gauge by-pass"
I saw that I was going to be installing upgraded items so I decided that I needed a new wiring harness altogether. So I went with the EZ-wiring harness. I didn't realize how bad the factory wiring was until I got in out and it was laying on the floor. EEwwww!
The relays are the life savers.... the old wiring lets say for your headlights just turns into a "trigger" wire instead of carrying the load. You're going down the right path... just keep doing what you're doing.
