Hi
I bought a 05 5,7 Durango for towing my trailer here in Norway. It’s an import of course and had to be converted to fit the laws and trailer system. I recently found an American made box trailer and it would be cool if I could use it without converting the break system from electric to mechanic. We don’t have electric breaks.
Ther is still a square 4 pin connecter on my car and a second lead coming out of that loom, can that has to do with a sort of trailer connection?


The US made trailer has a round plug.
sorry for the long question.

 

If the trailer has a round 4 wire connector, snip it off and put a flat four on it to match your pigtail. If your locality requires brakes, you'll either need a brake controller or convert it to surge brakes. Now, I guessing here but I suspect you have the flat four on the vehicle and the round 7 on the trailer. There is a conversion plug you can put on the back of your vehicle. It has the large round with a fat four next to it so you can use either one. I'm on the road right now or I'd take a photo of my set up on my truck. Unless you have a brake controller, the brakes won't work but the lights will.

Keep in mind that there are numerous different round plugs. I've seen round plugs in 4, 5, 6, and 7 wire connector. Some have the RV blade connector and others have the round pin connectors. This is similar to what I have.

On mine, you plug your flat four into the back and if you need to add a brake controller, power to the trailer or what ever, you wire it up direct. This will let you connect either one directly into your vehicle.

 

Thanks
We have to have brakes on everything above 750kg 1600 pounds
The car has now a 13 pin plug which is standard here, so I have to connect the brake controller separately and just change the connector on the trailer
How would I see if my car has a brake controller, sorry never seen one and don’t even know how they work.

 

Very few came stock with an actual brake controller. Dodge should have the connector for it stashed up above the pedals somewhere.... The controller itself, you will likely have to order.....

 

I can see the weight requirement fro trailers. Especially where snow and ice is likely. I'm wondering what kind of trailer would use a 13 pin plug.

An electric brake controller sits under the dash. When you step on the brake pedal the brake light will activate it and a pendulum inside will swing forward as you slow. This increase the current to the magnets in the brake drums. There is also usually a lever you can use to manually engage the trailer. Like going down an icy road to keep everything straight rather than jack knife the tow rig. Surge brake are mechanical. There is a master cylinder on the tongue and as the unit slows, the trailer will push on it like pressing the brake pedal.. They are simpler to hook up but require more maintenance.

Hopkins and Curt are two trailer equipment companies that come to mind. You can order a controller and the required harness for your truck through them. Whether that will meet local requirements, I can't say.

 

Thanks allot.
I only use 7 of them 2 indicators,1 break ,2 tail, reverse, fog, ground, and the rest is for charging batteries or constant power.

 

Just off the top of my head, your 4 wires for the trailer are White is ground, Brown is tail lights (both of them on one circuit), Yellow and Green are turn and brake lights. I don't remember off hand which is which, but the brake and turn signal is the same bulb. The other three are one is constant trailer power, and the other two are power for the brakes and a heavy ground so they work. I just got in from a 1600 miles trip and dealing ith a screaming 2 year old, a whiny 7 year old and the nice new air mattress got "obtained" and I slept for nearly a week on an uncomfortable couch that is smaller than I am. Let me get some sleep and I'll take a picture of my setup.

 

Hed to make the turn signal yellow, but it’s still the same circuit, just a extra sett of bulbs inside the clear reverse lights.
I can imagine you need some sleep after a 1600 miles trip. Distances on the other side of the pond are something else.

 

I checked my turn signal wires. Yellow is left and green is right. U.S. four prong is pretty standard. My 2016 Mazda required an adapter to convert the wiring into the 4 prong. I think newer U.S. models are going with the separate brake and turn signals. I'm not a computer geek so I work with older stuff.

A lot of the Brits make fun of Americans because so few have passports. Why should we? America is large enough we don't NEED to leave. I transited Alabama twice, once down and once back. The American state of Alabama is about the same area as the country of England. I remember talking to a truck (Lorry) driver from England once. A run of 200 miles required planning and preparation. Here, a 200 mile trip you just check the oil and make sure the fuel tanks are full.

I've realized the kiddies are generous. I don't know what they gave me but it's got me down. I've told the GF, the NEXT time we go down, we're breaking the driving into two days. I'm nearly 70 years old, I'm retired and don't work so I don't HAVE to be in a hurry. When I was 20, I'd drive a truck for 16 hours, take a 2 hour nap while the lumpers did their thing, then wash down some caffeine with a coke and drive for another 4 hours before getting a room and sleeping.

 

Compared to other Europe countries Norway has some distances too the longest road is about 1600 miles and that is from the bottom of Norway to the top.
I managed to take a picture of the trailer
any thoughts about the brand?
