Thread: Wiring How To

Tweet

I never could solder wires, maybe didn't have a good gun. Well anyway I use crimp connectors for everything. I have a good Thomas and Betts crimper, Channelock sells the same one (Don already mentioned). I do use the insulated connectors a lot but for a harness I would get the uninsulated ones and use heat shrink on them. Tear apart a factory harness and that's what you will probably find. Very few soldered connections in one. I also like to index the seam on the connectors so the dimple on the crimp is opposite of the seam in the connector, seems anal but it is a much better crimp than any other position IMO.
Other than that just keep it clean, keep the wires cut at the correct lengths, use good wire, lots of retaining clips and loom. Plastic loom is easiest but I like the old braided kind better. Also I tear apart factory looms for the wire, it is good quality and you get lots of different colors.
