Trailer recepticle pin outs

[WillWagner]

I've been looking thru the TMs I have and can find no diagram of the recepticle pinouts for the trailer plug. Just wanna know what pin is what. Anyone have or know where to look?

I can't search for it now but olive drab website should have it Will.

Thanks Kenny. Now, which pin is "A", then "B", so I can have a reference point. The plug on mine has no IDs on it.

starting with the keyway at the top, A is to the left and then go anticlockwise on the outside ring of pins, B C D E F H J and you will be back at top right of keyway. then the 4 in middle are top K, bottom M, left L, and right N. (i am only pretty sure this is right)

Thank Tom. I asked this 'cause I put the "new" trailer cord on the trailer today, used but never on a trailer. Had a couple lights that didn't work..including the b/o brake..no vdc. Fixed all except the b/o brake..grounds, who woulda guessed?. Pulled it 10 mi, stopped at a friends, no lights at all on the trailer. I expected the worst. Checked voltage and grounds from the truck, all the way to the trailer lights. All fine. Turns out the bulbs were 12VDC!! DOH! Put some 24VDC stuff in the lights, they are fine now. As for the b/o brake, well, no brake lights on the truck ether. see "another deuce brake problem" I do a check of the lights b-4 I drive it every time, light sw. to service drive and put the ts lever to flasher and do a walk around. Guess I need soldier B to check if I have brake lights! Never thought about that.

I'm surprised it isn't marked. The rubber molding should have the letters in relief, just look at it from the right angle and with a magnifying glass if you have to.
The image of the connector is from an M52A2.

back up to a mirror................

this is also the plug numbering scheme used on the lighting switch, just smaller.

Now we're getting there. What about turn signals? Anyone know off hand which ones?
I'm setting up my trailer, & all I need are tailights, stop, & turn signals.

Stop and turn signals should be the same, "B" and "J" for left and right respectively. Your turn signal switch keeps track of it all.
