I'm moving this to General Rodding Tech. You all make good points and have good suggestions, and this has gotten beyond the scope of the Interior forum.

Wire Gauge is determined by the current draw of the load. Most wires for signaling such as Temperature and Oil pressure Senders are 16 Gauge. Lighting circuits can be also 16 Gauge, but I prefer to use 14 Gauge.
12 Gauge is used for Headlight Relay Feeds and Heater Fans and a 10 Gauge feeds the Fuseblock from the Battery or master shut-off circuit.
I use the largest cable I can find to go from the battery to the starter (#4 at the least) and I make sure I run a ground strap from the battery to the chassis, chassis to the motor and chassis to the body (using multiple ground straps if separate body parts exist such as a truck box and cab).
If I am wiring a pre-50's hot rod I prefer to use the older style cotton-braided wire which I get from The Brillman Company (http://brillman.com/store) and in many of those cases I build my own fuseblock using parts from http://www.wiringproducts.com or other local suppliers in my area.
If I am wiring a 50's or 60's vehicle, I still like to make it more custom and tend to use general harnesses from various manufacturers such as EZ Wiring (http://www.ezwiring.com) and American Autowire (http://shop.americanautowire.com).
