Trailer Light Wiring/Plug

[asg13]

I have searched and cant seem to find the answer I am looking for. Unlike most here, I have little mechanic knowledge so therefore the green machine is going to the shop for a tune up and to fix a few odds and ends.

One issue I need to address is my trailer wiring. My truck is still 24 volts. Is there a plug and play application that I can plug into the existing plug? What are the chances it is still operative? Or should I have the shop rig something up to a traditional plug to work with my trailer now.

Thanks in advance.

Your truck is 12 volts, except for the starter circuit, and part of the glow plug circuit. The rest is 12 volts, pretty much stock GM.

There are adapters you can buy to go from your NATO plug to a standard 7 pin RV plug. I don't remember where I saw it, but it was over a hundred bucks.


To me, the simplest thing is to just replace the NATO plug with a standard civilian plug. Unless you see a need to keep the NATO plug....

Helps to know what vehicle you are working on. And what type of trailer connector you want. 7-round, 6-round, 4-flat, etc

Many have used the t-connectors and added a 4-flat, but it does take a little modifing

Which truck do you have? The M1009 will require an adapter if you don't want to tap into or change the existing wiring. There are threads here on making an adapter to plug into either the NATO plug or the weather-pack connectors that feed the NATO plug. If you have one of the other CUCVs, M1008, etc, then the commercial trailer light adapters for that era truck should be plug and play with the correct harness from places like etrailer, etc.

I just went down to a local u=haul and had them add 4 pin one cost a whole $15! I don't know if it was that cheap as I was also getting a tow dolly or not but that is all they charged me.

Mules, did they use the blue scotch-lock connectors? They allow water in the wires after awhile

Sorry 1008

Yeah, after a not very long while. I would not trust U-Haul to install a light bulb.

If they used the scotch locks, pull them back off and squeeze silicone in them. You'll not have any issues.

If you've got connectors with the single blade (like the blue one below), get rid of them. You want the kind with the double blade (like the brown one below), and fill it with dielectric grease before you make the connection.

Much mo' bettah!


By the way, the color indicates the size wire it fits. You can get either kind in red, blue, yellow, and brown.
