Best off road trailer plug

[boxing kangaroo]

sorry if this has already been posted i did search within the forum and couldn't see anything.

I just brought a used Horizon adventure trailer and am doing some re-wiring on it and have realized that the 7pin plug isnt going to be enough once you add in AUX reverse lights and some other additions.

In Australia we have 12 pin plugs (see image) is there anything similar in the USA? i have been doing google searches and all i can find is 7 pin over here.

cheers

Just to clarify i currently live in Florida.

cheers

Reverse,fog,and 2 aux ports??!!

Sorry to sound like a 10 year old girl when justin bieber walks into the room. I just have never ran across this item before. Please post A link if you run across one here in the states. Thanks

7 pin is the largest US standard trailer plug. You may be able to find something with more capacity that are used with the big rigs.

The other alternative is to wire your 12 volt connection between the vehicle and the trailer using an Anderson connector, that would open up one port.

Hey Martyn,
I plan on using an anderson with a bigger gauge wire for more amperage and faster charging to the 2 house batts. yes that will free up 1 port but i need more.

I think im going to have to buy this back home and get it shipped over here. I'll post a link of where to buy when i do.

Also the beauty of this style of plug is that anyone with the 7pin version for just the lights can still plug into your 12 as its just the top row. (see attachment)

That is a very nice feature. If there was enough interest may be it is something we should import??

Iv been researching connectors because I'm not satisfied with my plastic hopkins connector. I'm sure the standard 7 blade design works fine, while having it's limitations as any. But I'm not a fan of how big and disposable all of the ones I found were. And the wire clamp seal was weak compared to a cast aluminum connector.
I think I will order the ISO 3731 commercial style for its smaller bumper hole dia and cast aluminum construction. I also like the one pin which is a reversed socket for the fact not anyone could hook on with lights. Then make a adapter or two.. Because if for any reason your rig needs to be towed, the towing company will not if they cant get lights working.

Verkstad, Thanks for the information i think this may be the way to go in the USA use 2 plugs one standard 7pin for lights and another for auxiliary lights ect. It just means im going to have to have 3 plugs going between truck and trailer. as i have a dedicated power anderson plug for faster charging of the batteries in the trailer.

Cole Hersee makes a 12-pole trailer plug available (and made) in the USA...

"Flat profile design provides a robust 7-pole or 12-pole connection. Housings are molded thermoplastic material, resistant to ultraviolet solar radiation. Nickel-plated brass terminals with split contact pins give a positive connection. Insulators between each terminal provide protection from short circuits. Spring-loaded socket lid protects the terminals when not in use. Insulated cable clamp secures the cable, minimizing vibration and strain. Terminal covers are easily removed for access to terminals. Pins 1-7 accept up to 14AWG wire, pins 8-12 accept up to 8AWG wire."

Awesome Thx Hoser thats what i was talking about... wonder if there is a connector for this to a standard 7pin for when other ppl tow my truck or do i need to make one?

Stupid question I guess, but what do you need the 5 extra wires for? It would seem easier to run a 7 pin to a distribution box for the extra accessories, with the proper fuses for each one. It makes the trailer more user friendly it seems. Very few will have the 12 plug and it would require an adapter for someone else to tow it.

I run a 7 wire plug to a Progressive Dynamics electronics control box. It allows 12 fused connections, 110 wiring and smart charging of the system when plugged into 110, also allows for solar and 12 volt from the vehicle. They are not very expensive (less than 200 bucks), they give you a mountain of options.

I think you would need to make that yourself. They also offer a 13-pole connector...
