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.
