I want to extend my wiring harness so I can relocate the computer and fuse box. Are there any wires I need to be careful with(i.e. resistance sensitive wires)? Also, does anyone know where to get the factory style harness connectors? I would like to make a plug/play extension instead of using a bunch of butt conn.

As long as you use the same gauge wires you should be fine man, and I would check your local ford dealership for the connectors, I was able to make my own fuel pump harness with the plastic connector they had.

^ agreed and i would hit up my local junk yards for a full computer harness adn just cut off what you want/need. and any 12 volt wire will work. im not a huundred percent but im fairly certain none of the wires are resistance sensetive youd have to ask ranger man james about that for sure.
