Works ok though wire a bit small, no directions so, wish wires were a bit better organized

Works ok though wire a bit small, no directions so, wish wires were a bit better organized
This works decent, appears to be like 18AWG wire, and is near as I can tell pure copper. The wires do not show any specs on them and I wish the wires were all paired together instead of splint into two pairs. The ground wire is plenty long enough for even longer tongs. I rewired my trailer after the plug got damaged and old wiring was starting to show age. I had to verify online the color codes for what is what but ended up matching the old too. I also replaced the end of the car as the old one had severe corrosion damage.This does not come with anything to connect this into the existing systems I used the solder-filled heat shrink splices to hopefully ensure a solid connection and watertight seal. The car side was a bit small to fit my Ford's holder so had to modify the holder a bit. Apparently, there is not standard size as far as mounting these plugs. If you have issues with this and find nothing works check your ground first.
