Confidence

I feel your pain. ONE CIRCUIT AT A TIME. Don't try to get it all wired in a day. When you get done for the day, go over in your head what you accomplished and what you would like to do next. Sleep on it and don't be surprised when you wake up with the answers!

That's what I've been doing. I got the harness laid out and am bolting the new relays to the firewall and inner fenders. One step at a time. It'll get done and be done right.
