When rebuilding a car or motorcycle, or wiring a race car, it is often easier to rip out the old wiring and redo all of it. Today I will show you how to plan it out and do it with the correct connectors, wires, and tools. It’s easier than it sounds and cheaper than you might think.

    Hey matt what program or tool do you use to add animated things like your graphics for the "holy trifecta" of cheap/lazy/quality?

    I was trying to repair my electrical system and just kept finding different wires failing so I lost my patience ripped all the old crap out and did it all from scratch using a 12-volt Marine fuse box as my hub. Been using 10 and 12 gauge wiring only. Thicker the better. Fuse box has two 4 gauge wires running to it for positive and negative output. When I love most about my nephew's boxes it has led so when a fuse goes after you know which one without having to pull it.
