Wiring kits?

The Ron Francis 300 dollar one is actually a good deal. Each wire is printed label on the wire to where it goes and the directions they give you is very good almost trouble free. I think it’s not smart to just run red and black wires to everything. Good luck finding a problem down the road or the person cussing your butt out owning the car next.
My son and Grandson will own the car next and so on. I would think again I would have a hard time not knowing what's going on with my electrical wiring if I ran all 27 wires myself no matter what color they were. I would know what ran what and I can find one end of a wire with a simple continuity tester right?
