trailer adapter splicing- connector

[CADjockey]

Good Evening!
Just a quick question. It has been a while (long time) since I have had to do any kind of wire splicing.
I am rewiring/making an adapter cable (6-pin square plug to a 4-pin flat plug) for a recently purchased used trailer. The trailer has a 6-pin plug but no electronic brakes have ever been on the trailer. I have a decent multimeter to verify good continuity.
My question is what kind of splice connector would you recommend? I have some crimp type connectors, and some shrink tubing. Is soldering recommended for this application?

I would check out e trailer for some "plug and play" wiring so you don’t have to splice wires.
Without knowing the vehicle manufacturer here is a sample for a Chevy.

Cut off the 6 pin connector, get a 4-flat stub, use **** crimp connectors to connect the stub.
Stagger the crimp connectors so they're not all bunched up.
Slip on some wire loom for a finishing touch.

If you ever decide to put brakes on it, use a 7-round like normal people do.

I would not ever use a **** splice other than this one (there are 3 variants for different wire gauges). Moisture will inevitably find and corrode standard **** splices or unlined heat shrink tubing in an outdoor app like a truck or trailer, and we all know how that goes when you are attempting to hook up after dark. This one has a "hot glue" which also melts to seal the connection. One has to crimp responsibly with the proper tool and resist the temptation to use a pliers which will gouge a hole into the jacket as the tube is being crimped.

Agree with 100% on using nothing but industry standard 7- and 4- way connectors.

Easier to check for a ready made adapter.

The 4-pin flat will plug into a 7-pin round adapter that I already have for the truck. I just need to have some way to use the wiring on the trailer. For whatever reason that is using the 6-pin square. Up to this instance, I had never seen one before. It is built into the trailer frame, so it is rather tidy, but I would agree, completely non-standard.

What the hell is this sorcery



I would get something like this (random endorsement, might look for a "better" one):

And one of these

To make an adapter. Or just cut the 6 pin off and use the 7 pin plug on the trailer

Does trailer have electric brakes or need auxiliary power? Is it a camper? I'd leave it and buy an adapter.

In the frame? So there's no pigtail?
Must be somebody's idea of a better mousetrap.
Some pictures would help on this.

As above, cleanest is to rig up a 6-square to 7-round out of available parts.

Adapter is my vote.

That adapter is exactly what my end game is. Well done finding that!
After shipping and tax, it looks like it is $62 and change.

I had found an old 6-pin square female connector (the colors of the wires are not matching current 'standards', but the location is correct) and a 4-pin flat make connector. I already had a standard 7-pin round to 4-pin flat flat adapter plug, so I was trying to make an adapter cable to go from the 6-pin square to the 4-pin flat. Like it was suggested, I had planned to cut the wires on each then splice them together to make the adapter cable. I do have plastic spiral cord wrap to give it a nicer finished look and to provide additional protection.

Many thanks for the comments!

I have a decent multimeter to verify good continuity.

Yes, it will verify continuity, but always test after with the bulb in the circuit !

My question is what kind of splice connector would you recommend? I have some crimp type connectors, and some shrink tubing. Is soldering recommended for this application?

Solder not required.

Personally, I prefer non-insulated slices and marine/dual wall heat shrink.
