24v trailer wiring

OUTSTANDING! Thank you Rob, I will give it a try.

Always glad when all that redundant info floating around in my head can be of use to someone. Good luck.

Depending on the age of your trailer harness, it may or may not have the 22-460 and 22-461 wires marked. It may just say 22. The 22 will be the rear left (22-461) while the wire coming off pin J will be 22-461.

Recently when ordering LED bulbs for my trailer I remember them being 12/24 volt bulbs. If you just switched to LED bulbs would that work?

The multi-voltage LEDs are becoming more and more common. They will not solve the trailer connection problem, but are ideal where you want to switch the trailers between SMP and commercial towing.

The Truck-lite SMP tail lights (the large plastic kind) are now available in 12-36 volt range, and are also perfect for a jeep trailer that occasionally gets towed behind the family pickup.

Could you dumb it down a little bit. All those straight lines, numbers and obviously deceptive symbols are confusing me. I keep thinking that in 1953 Motor Coach Industries would have been more technically advanced. *Sarcasm mode off*

Although it might sound implausible, I had something else happening that day.

Judging by the pics, it looks like it was an Iltis Kids get together anyway. God forbid one of us M Series guys showed up.... All the ridicule Iltis Owners get requires a pack mentality

Yupp.... I think it is great that some of the local MIL vehicle community can come out and do some public service living history events. It is OK, us Iltis Kids are very inclusive, and would enjoy sharing a burger with the M series guys and gals.

Cheers!

Stuart, I never miss an opportunity to take a little poke in jest at the Iltis guys

It looked like a great event. Sadly, my Day Job kept me away.

It is just a matter of swapping in some 24 VDC bulbs, Make a good quality harness and you can lend it out in the Ottawa region...........

I've tried troubleshooting the wires and connections. How does the ground connect to the trailer wiring harness? It is a round spade fitting, but I've never known any fittings other than the rubber cable.

Just a word of caution on "NATO" plug wiring and trailers.


There is a clash between North American and (you knew it was coming) British NATO connections.

You might wonder what I'm jabbering on about but let me explain. There is a presumption that all NATO kit is inter operable.

We found to our cost over the years when trying to connect a British prime mover ie Land Rover or Bedford to M series trailers that things go squirly.

The reason is that the British stuff uses a separate bulb for the turn signal but the North American uses the brake light.

Just in case anyone has aspirations of towing things

Stuart,

there is no question that you are a learned fellow, but sometimes you miss the point hugely.

What I'm saying is NATO truck to NATO trailer does not work a times, that was the point I was trying to get across.
