Since i can remember

I have always seen and had those round six way plugs for our trucks. They are almost universal to me, goosenecks, and tag trailers should have them. I now look around and see that in my toolbox i have several different adapters for all sorts of trailers now, Four way flats in particulat and even the seven way rv plug to accept a regular six way.

Now granted these are teh way to go (adapters) i mean, But it leads me to question, Why are many trailer makers switchin out to four way lights on these trucks?

RVs are understandable, but not most other kinds of trailers. I saw a used two horse gooseneck yesterday with the four way flat, These cannot be better than the other six ways that were all used to, are they?

Any thoughts?

In my opinion (which can and often is wrong), I think that the manufactures are going to a more standard plug type approach. A flat 4 way connector for a trailer with just lights and a 7 way rv type connector for anything with lights and brakes. I have rarely seen the 6 way connectors except on a few older horse trailers. My 06 Ram came prewired with the 4 way connector coming out of the bottom and the 7 way on the top near the license plate. My 2000 Dakota was only wired up for the 7 way and it came with the adaptor from the factory.

Does the 6 way connector still come standard on horse trailers or has most of them migrated to the 4 or 7 way plugs?

 

All of the cattle trailer

and horse trailers ive hooked have the six way to them, which is why i wonder, why change something that already works?

well rick, all the goosenecks that ive hooked onto have the round 6 pin plug. but all the bumper traliers (boats, single axle jobs, etc) have the 4 pin inline plugs. i never knew goosnecks had the inline style plugs? humm....


lol dodge also has their own style of plug. dad has one on his truck. hes got all 3 mentioned, however i only have the one 6 pin style

 

Can't have electric brakes with only 4 plugs that I know of...

 

I'm glad my truck came with both plugs. One for each of my trailers....

 

I always figured that 6 was for goosenecks, 7 was for travel & car trailers (or anything big with brakes) and 4 flat was for light trailers without brakes. At least that's the only way I've seen them...

 

Yeah same here

I counted up, i pull around 14 different trailers, longest one being 36 foot stock trailer (havent loaded it up yet) and only one of them has the four way plug.

Yup it is true, u cannot have brakes or auxillaries with a four way flatt, I was just curious on this issue..

Thanks guys!

It's too bad they can't all be standardized. In my opinion the 6 pin connectors are far better quality than the 7 pin. Nice cast aluminum instead of cheesy plastic. Another superior connector is the 7 pin with round pins- used on heavy trucks. It would sure be nice if auto and trailer manufacturers could get together and design one high-quality connector.

 

I like the 7 blade style. It supports back-up lights on the trailer.

Most of the trailers I encounter are setup for 7 blade.

 

I agree with Trey. Even my little trailer has the 7 blade. But it would be nice to have backup lights on it...

 

4 flat = LT,RT,STOP & MARKERS.
From what I have seen most of the stock and horse trailers still come with the 6 round. The 7 blade or RV plug is more common when you go to an Enclosed, LQ, dump trailer or something with a winch were a heavier gauge wire is needed for good power source.

Um you can get a metal 7 blade rv connector.

 

Looks like plastic on the inside to me

 

Need some sort of insulator.... Make the whole thing out of metal and it would short out....

Those plugs pictured above are a big improvement over the completely plastic ones....

There are even some good plastic ones.... better grade of plastic....
