4 prong trailer wiring T connector

Hey guy's bare with me, I'm really bad at electrical stuff and I'm ah little lost. I searched the archives and didn't see an answer to this seemingly simple problem so here goes. I bought a (flat, 4 prong plug, T connector ) for a 1984-K30, and as per the instructions plugged the T in between the drivers side tail light plug. The drivers side lights of the trailer are all functioning properly ,but the passengers side only has running lights, nothing else. Does our CUCV's have different tail light wiring then a civilian truck?

I just got back from Walmart and I saw this http://www.walmart.com/ip/Hopkins-47185-Multi-Tow-Adapter/16782535, How hard would it be to bolt this in place of the military plug & wire in?

It probably won't fit where the military plug is due to the length (it will hit the pintle support behind it). I have my 7 blade connector just to the right of the military connector.

Well here's what I came up with today I went ahead and bought this (Hopkins 7 round multi- tow connector) from Walmart http://www.walmart.com/msharbor/ip/Hopkins-47185-Multi-Tow-Adapter/16782535 after taking some measurements below the military plug and also behind it. This worked out perfect ,it's just below the pintle hitch bracket, and just above the receiver hitch bar. Plus I think it looks cleaner being in line with the original military plug, and both function in case I ever find myself needing to pull ah military trailer.

Have you tried a military plug in your truck with the 7rv below it? I'm betting it won't fit.

Interesting. Your military plug rides a lot higher than mine. Mine is pretty much in the middle, vertically, of that space. I'm planning to just replace the military plug with a standard 7 pin RV plug. I have no expectation of ever towing a military trailer.

How's the clearance in back? That's my biggest concern - the back part of the 7 pin looks like it's too big to fit in there. That angled brace back there sure limits the room.

(Dstang), No I haven't seen, much less used ah military plug so I'll have to look into that. (Marcus), If you look close at my pic you can see that the new plug sits lower then the pintle, thus the long back of the plug goes under the bracket. Otherwise if I tried to install it IN PLACE of the military plug it would hit right into that bracket. Also as ah side note there would have bin NO way to get the nuts off the back of the military plug without removing the whole bumper. Yet another reason for me to just do it this way.

OK, so my brother-in-law calls tonight, says he needs to have me
bring the truck to pull someone else's trailer, and all of a sudden
I need a trailer harness for 4 flat coupler (I hope). Will the 67-83
plug work correctly or not? If I have to fab up the curb side wiring
on a plug I have to buy, I'll just fab the whole thing.
Thanks guys

Okay, dunno what I was thinking. Mine is just like yours. I guess I'll have to mount mine like you did. There's just no way to get that 7 pin in the existing location. They just stick out too far in the back.

One thing that concerns me is clearance for the military safety chain, with the 7 pin so close to that hole. What are you towing with it, and have you had any trouble with that?

A military trailer plug will not fit in the original outlet the way he did it.

Well the safety chains can go down into the holes on the receiver hitch below the bumper. As for the trailer plug. The only thing I see from pics online that may be in the way is the cover flap on the trailer's plug. I wouldn't know for sure until I tried it. There's 1-3/8" space from the bottom of the mil-plug to the top of the civ-plug. And the civ-plug sticks out from the bumper 1-3/8". So again really hard to say if it would or wouldn't fit until I try it. Here's some better pics....

Even if it doesn't fit it's easy to just convert to 7rv. It's just easier anyway.

Chesapeake, This is the thread I was talking about. I just spliced into the original military plug and mounted the civ-plug just below the Mil-plug. It's critical were you mount it because of the pintle brackets behind the bumper.
