Please don't take this as a whining session, but rather advice learned the long, hard way.
Are you color blind, or just cheap? I'm a card carrying cheapskte, but
PLEASE DO NOT REWIRE YOUR TRUCK WITH ALL ONE COLOR. If you're color blind, please consider that you may not be the next guy wrenching on it, and wire numbers rub off. The Air Force wires all our equipment with white wire with numbers, and we spend a lot of time reading wiring diagrams to see which terminal a wire is supposed to go to because we can't read the wires. I had to re-wire a nitrogen servicing cart control box that burned, and even with two example boxes, a wiring schematic, and a wiring diagram I had to guess what a couple wires were. Go here and order the wire colors you need.

I'm re-wiring my race car from scratch. The previous harness was a mish-mash of colors, and wrong wires got cut and spliced when other people installed stuff in the car. I spent about $200 on all the wire I need to build the harness from scratch. It's completely worth it because I'm going to put a laminated wiring diagram on the firewall. If anybody splices into a circuit that's not the white accessory circuit, they're gonna get shanked.
Use frame grounds. Keep them clean and tight and they work. Ask anybody who's had to wire a fiberglass car. Running separate grounds is more troublesome.
There's a reason the industry standard is colored wires and frame grounds. It works. You're not going to "beat the system" by deviating in this area.
Also, #14 is big. I'm running nearly everything on 18 gauge. Circuits that need more current, like the radiator fans, are getting quality 12 gauge wire. A stock alternator needs at least 10 gauge. Consider 4 gauge for a big alternator. The battery cables are 1 gauge.
Here's my wiring diagram if you'd like a reference.
