TT 7 pin plug - Universal?

Currently towing my TT with a 2014 Toyota Tundra. Looking to purchase a 2017 Dodge Ram 2500 HD. Question, are the 7 pin plugs set up universal? Sorry if theirs seems silly but of course nobody at the dealerships knows.
Thanks

The 7 wire round is often used on large agriculture equipment when towing on the highway. While that may not have brakes, they have a lot of lights. And you did get the same answer I was going to give on the trucks being universal on 7 wire blade that I have seen. In fact I have not seen a camper with electric brakes since the 80's that did not have 7 wire blade cord set. Years before the 80's there may be some round 6 pin I think.

Thank you all. Thought they were universal but wanted to check.

A lot of talking around your question, but to answer, yes, the trailer plugs that come as OE on every truck I've seen (the big 5 anyway) for the last 15plus years are the same 7pin, blade type. It is pretty much the universal standard for trailer wiring with brakes, backup lights and 12V charging/accessory lead.
New Ram will have the same 7 pin blade as your tundra. Provided that's what you have on the truck and trailer currently.

Factory installed plugs are universal.
"Joe backyard mechanic" installed plugs may not be.

My previous 2004 and present 2010 Ford trucks were equipped with the 7-way blade type receptacles. Both were actually a 7-way BLADE type and 4-way PIN type combo unit with spring locking lids like shown in this google image...



All of the 7-way trailer cables I have ever been associated with were using the 7-way BLADE type plugs... I have seen a 6-way round pin type cable plug on a Truck Camper setup which was using an 6-way PIN to 7-way BLADE adapter plug on it which plugged into the truck 7-way Blade connector. Another issue you will have is the truck also provides for Trailer Brake wiring to the 7-way BLADE type mounted receptacle on the rear of the truck. My 2004 Truck had a hanging trailer brake cable in the console area to plug into an after market Brake Controller module. My 2010 Truck had the brake controller built-in like shown here...

Etrailer makes an adapter cable kit just for this type of setup for the Truck camper unit and a fifth wheel unit to install up on the inside of the truck bed and will route back the 7-way Blade Receptacle on the rear of the truck...


I'm sure ETRAILER has the 6-pin version of this extension setup as well. You could have both 7-way and 6-way connections onthe inside of the truck bed wall like this photo shown on google...


My small utility trailer I tow behind my truck is equipped with the 4-way round pin arrangement and will plug into the 4-way side of the dual combo setup I have.


I am thinking you will most likely only see the 7-way BLADE type units being used as the standard universal connector... If I was adding the trailer connector to a truck I would go with the 7-way BLADE and 4-way PIN combo receptacle like shown above...

Food for thought here...

If you are going to be buying either or both Plug and Socket, BUY REALLY HIGH QUALITY. Hopkins is good and may be as good as you'll find. I think the BLADE type is the standard of today but the pin type is also good.

Just don't scrimp, one of those wires will be your charge line and the other circuits are safety circuits, lights and brakes. You don't want failures from using cheep cr-p.

Sorry about the language, I am just into good safety equipment connectors.

If both are factory installed, they are the same.

The way it should be.
Sometimes a local installer may screw up
Or the trailer may be wired wrong
