I have plenty of time and I also will wire my own. While not an electrician, I do want to route things 'my' way so it looks professional. I notice plenty of different gauges of wire (besides colors) - what's the thinking of using 12 ga throughout and either band the ends in a colored tape or heatshrink ? Call me crazy, but I just rebuilt stupid Fiat motor last year, so anything else is cake.
There are a few reasons you may reconsider you choice of wire gauge:
1) Some of the wires are 10 gauge.
2) Cost. The cost is 12 gauge is much more than 14 or 16 gauge. At Autozone:
12 gauge primary wire, 100 ft = $44.99
14 gauge primary wire, 100 ft = $22.99
16 gauge primary wire, 100 ft = $18.99
In addition, your connectors are quite a bit more for 12 gauge.
3) 12 gauge connectors may not fit on some of the terminals and your wire loom will end up being really big especially coming thru the firewall. You may not fit that many 12 gauge wires thru the existing hole.
Look at the existing wiring diagrams for gauges, then alter it to fit your needs and preference's.
