I recently purchased a universal 21 circuit wiring harness from the internet. I'm so confused, I could use a lot of help. My 50 Chevy wasn't wired with a fuse box and the original diagram is very different from the new diagram. For example...the headlight wires go directly to the headlight switch on the original diagram. My new fuse box has two wires, one is the headlight power, the other is the instrument light power. I assume the headlight wire now goes to the back of the headlight switch. The instrument wire also goes to the headlight switch, right? Can someone please explain this.
I can use a new diagram that will show me how to run wires from the fuse box to my stuff. Thank you.
