I found that laying out the wiring in the car gives you a general idea what
device the wires should go to. The wires are all about the right length to get
where they need to be without a lot of extra length. Get a color diagram from
Prospero's Garage. It is easier to read than the hanes B&W pictures and it is laminated and sweat proof. I think I got mine on ebay.

when I finally hook up a battery to the car.
Put a 3 amp fuse between your battery and the positive wires. That way
the fuse will blow if you have a short instead of cooking your wiring.
Take all the fuses and relays out except the one for the circuit you are debugging.
Add them back one at a time as you work through the systems.
I have nearly all my wiring hooked up so we'll see soon how I did.
