Tacoma, When I rewire a rig I will use good quality marine fuse blocks and components. Most auto stuff is fine, but some of the fuse blocks out there are junk and have alot of resistance. Go brass. I also build my electrical systems with a panel that is hot all the time for stuff like CB, interior lights, manual back up lights, chassis lights, ect... I then of course build a panel that is ignition on hot only (or ACC). Buy a very good high quality set of crimpers and wire strippers. If you are really nutso, solder each connection and heat shrink it. Be sure to buy as many different colors as you can. Makes troubleshooting really easy later if you need it. They also make little number and or letter tag kits you can label your wiring with. Document it as you go. You will hug your self later when you try to remember where that wire goes. Centec, painless and a few other companys make some pretty good kits. I believe some even have silicone insulated wires. Lasts forever and flexible in the cold. Good luck and have fun....
