I’m doing some wiring now on my truck. I’m not too great at it. But it is very slow going. I use non insulated terminals and that heat shrink with the glue in it from Harbor Freight. It works pretty good.
I use wire and terminals made by Noble, usually available at commercial/industrial shops, hydraulic hose&fitting suppliers. It’s US made, but it’s a touch better than what you get at the auto parts stores. Not nearly as good as an SXL type automotive wire though.
