Wiring for 6 pin connector

[me4osu]

I purchased my rig used, and it has a round six pin connector in the bed and on the bumper. The guy who had the truck before me installed these two sockets using scotch locks to make wiring connections. I would like to solder and heat shrink all connections, get rid of the scotch locks and verify that all connectors are wired up correctly.



Does anyone have a wiring diagram showing what the standard six pin confiuration is? In other words, which pin controls what? Also, a wiring diagram for the rear lamp circuit would help too.



I performed a search, but could not find a thread containing these items.

Thanks.

Eric,

Note: I make no guarantees whatsoever for the accuracy of this diagram!

I have the 7 pin large type and pulled a trailer wired with a 6 pin connector.



I bought an adapter from the 7 pin to the 6 pin and the 'manual' for the adapter stated there are no standards for the 6 pin connectors.



I had to switch the battery wire and the brake wire in order to move the trailer without the wheels locked up.



The trailer had a sticker attached that showed the wiring configuration - handy idea.

The diagram that Rusty provided is the same as what U-Haul uses and I've seen it on either Bargman or Polak connectors as well.

BTW - I have the 7 pin with adapters for 6 and 4 pin. I think 7 pin is standard on cargo, horse and rv trailers and the 4 pin is more for small utility or boat trailers. 5 and 6 pin are odd IMO.

Thanks

I'm ready to start burning solder now!

6 pin connectors

I've generally seen 2 different "standards" for 6 pin connectors. One is just like that web page showed, the other has the accessory 12V and brake swapped. I guess it depends on the trailer manufacturer.



So, what I did was get a big DPDT switch and wire it such that it will give one configuration in one position, and swap the two wires in the other position. Mine also has an OFF in the center so I can shut the brakes off if I want to.



Why? Well, sometimes, when going SLOWLY down a real slick, fairly steep hill, the trailer brakes will lock up and cause a jacknife faster than you can imagine. Even if you have the brake controller set at minimum. With 'em off, they will never lock up. Of course, you've only got your truck brakes and engine then, so you have to go slower...

CJ,



Great idea!!



Edit - I guess the moral is you have to check every 6-pin trailer you hitch up to.

me4osu many auto parts stores sell an adapter that plugs in between the factory wiring harness and you just have to plug in to the harness and connect the other end to the trailer plug on your bumper! very easy and neat! try Napa for the right plug.

I'm a little confused. On the back of the 6 pin plug , on the plastic part, each hole says what it is for . That has always worked for me. Where is the trouble?

Try this link, it has the wiring for all the different plug types.
