Trailer lights wiring?

[QueTex]

Been having issues on my bbq trailer, lh tail lamp just wont work consistently, have replaced the whole wiring front to back with new one from Academy, then both complete tail lights, ground wire is good. So have concluded I need to replace the connector at the truck but it has 3 other plugs from previous owner so need to get rid of all and just have one for my use. Any links for the correct way to do this?

Perfect, just what I Ineeded thanks.

I've wired ALOT of trailers in my day. I do not ground taillights to the frame at all. I run a ground wire from every light to the front. Every connection gets soldered and heat shrink. Also, do not ground the trailer through the hitch ball. Run a physical ground wire through the 4-pin or 7-pin connector, whichever you have. If I had to put a number on it, I'd say 99% of all trailer light problems I've ever came across were ground issues. The other 1% are broken wires or corroded connections. Oh, and never use those blue connectors that stab into another wire for power or ground. Those also have connection issues. Solder, solder, solder.

Oh, and all trailers have universal colored wiring.

Brown = tail and running lights
Green = right turn and stop
Yellow = left turn and stop
White = ground

Someone should send the code memo to all the trailer builders. Seems like the guys doing wire on the rv stuff have a different code. My pace enclosed is nothing close to what I consider the right code. As you listed above.

Good info, thanks but actually the trailer is already wired right including the ground as you mentioned noxcuse, manly looking for the truck side of the hook up, will look around for that online, thanks.

I like the wiring sets you can get at the car parts store. You unplug the factory wiring harness and plug in the aftermarket one.

Yes I have that Rod, but my truck has two others spliced in too, one for gooseneck and another one is the smaller round one plus the third one we all use for light trailers. So I need to get rid of the other two.
tnx

You could use a junction terminal box and use as many pig tails as you need to

We use 4 and 6 pin commercial plugs at work and I am becoming a believer that the plastic rv plug has better connections. I have changed over AL my stuff to the rv style. And now have an adapter from rv to 4 flat or 6 round. All my bases covered with 1 adapter.

I agree and all of my trailers (6 at last count) all are setup with RV plugs our 4/6 flat run into a converter plug.
