M1009 Trailer Connector Wiring Diagram

I was researching trailer connector wiring for my M1009 to wire up a connector for a civilian trailer and found lots of information but it was generally in a format that was in my opinion either hard to follow or contained a lot of unnecessary information. I put together this document that I hope summarizes and illustrates the pinout and wiring connections necessary if you want to use the existing connector.

Enjoy!

Thank you, thank you, thank you ! This I can understand ! Might was to see about putting this on the FAQ thread it certainly belongs there !

THANK YOU!! This is something i need to do

Thanks for posting that diagram. I just purchased my M1009. Is there a connection for electric brakes in the original 12 pin set up? I would like to tow a small camper that has electric brakes. Also, will I need to reduce voltage to 12V for a Civi trailer?

The CUCVs have 12v at the plug. No conversion needed.

You will have to run your own electric for the brakes.

Thanks a bunch! This will come in handy for making an adaptor.

This is great but does anyone have the info to make a 6 or 7 wire civi plug(turn, stop, backup, park, trailer brake(opt), 12+, grd?

Mine is wired for the 7 pin connector, I did not do but looking at this diagram I can see how it is done , just use your blank pins.

Thank you! I was about to break out the multimeter, but you saved me a ton of time.

Where can I find the connector pins to attach to the wiring harness? Pins that fit properly in the military receptacle?

I got my here, http://www.amazon.com/dp/B005F9BCB2/ref=cm_sw_r_udp_awd_IQ-5tb1NDCY2E
and made up this.View attachment 508819 It plugs in here...

1. Starting system: 24v
2. Glow plug system: Part 24v, mostly 12v
3. Everything else: 12v

If you are towing a civi trailer, consider replacing the NATO connector with a standard 7 pin RV connector. Unless you plan to tow military trailers, or want it for the nostalgia/cool factor, it's useless.

Sorry guys new here it says attached thumbnails but can find or open this wiring diagram

Thank You from another CUCV Tennessee owner. You saved me lots of time.

I can't open the document. I have a 7 blade civilian trailer plug to wire up to my 85 m1009.

I think your best answer is in post number 11.

Here's my converter box that I made to tow my M1101 with my WK Grand Cherokee (Hemi) and still be able to move the trailer with the M1009. I should have used a larger box because my plan was to put a cigar lighter plug in it to run a light or whatever. The coil cord was from e-Trailer, the mil connector from a generous forum member, and Home Depot provided the rest. The trailer lights run fine on 12v; I was expecting them to be very dim but they looked good even in the daylight. The converter box is zip-tied to the trailer making it removable in case a friend needs to pick up a trailer from the auction.
