Wiring M101A2 to 7 spade on civilian vehicle

[devindemand]

Here's my dilemma... I've been to so many forums and websites I figured this would be the easiest way.
I'm try to wire the harness off a M101A2 to a 7 spade. I know the bulbs have to be changed out. That has already been done. It's the numbers on the metal clips that's confusing me. They don't match what everybody has been saying.
Could someone possibly give me a little direction here?

I would really appreciate it!

Thank you,
Dev

Use a multi-meter and check continuity up to the junction connections on the tongue then wire it up to the travel trailer plug.

I did it the easy way. I removed the lights and put on LED civi lights with a 4-wire harness and put a 4-wire to 7-wire converter plug.

Easy and it has license plate light and holder.

I have done a couple of them . Leave the lights. You can't beat them - they are shock proof/rubber mounted & water proof, but change the bulbs. Then cut the military plug off the end of the existing "trailer to tow vehicle' cable, Strip back appropriately for the seven flat pin ( RV Plug). Secure a hot wire from vehicle & ground trailer. Using hot wire, find the appropriate circuit that your looking for, ie. brake light, tail, Ground, etc. Wire them into them into the RV Plug. Disreguard the extra BO wires - cut them off/whatever. If you ever want to restore to the military standard, just replace the trailer cable plug pig tail.

Just get an adapter to go from the 12 pin NATO plug to the plug you are looking for. They are available and you won't have to mess with the wiring. I installed 10-30 volt LED bulbs on my M101A2 so I can plug the trailer into either 12V or 24v.

I missed that. OP, change your location to one of the states, not all the states. You agreed to this when you signed up!

Here are my notes from when I converted to 7 pin plug:



If that doesn't match what you've got, you'll need to break out the multi-meter and start tracing.
