I have a 2010 F250 with the standard 4 pin and 7 pin trailer connectors. I just bought a trailer that I need to pick up that has a five pin connector. Is there any way I can adapt the 4 pin to accept the 5 pin??? I will permanently fix it and add a five pin in the spring, But I have to go a couple of hours to pickup the trailer empty and would like to do it without changing the factory harness (No need for trailer brakes).

Another question:

Standard Utility/Cargo trailer (12,500 gvrw), Truck is totally stock XL package, Do I need a drop hitch, If so, How much of a drop??

Thanks in advance for any advice!!!!

 

What is the purpose of the 5th pin? I have heard that some trailers with surge brakes require the backup lights on the 5th pin to keep the brakes from activating when you're backing up. I don't know why, but that's what I heard.

I would make sure I knew what the 5th pin was for, then find the cheapest 7 to 5 pin adapter I could find. Or, buy a new 7 pin plug and put it on the trailer on the scene. You can do it with just a screwdriver, generally.

The hitch you will need will just depend on the trailer and the load. I'd get a pretty standard 2" drop for now and then see what you need later.

 

I believe you can get a 7 to 5 pin adapter, no need to rewire anything.

As far as the hitch goes, it all depends on the height of the truck and the height of the trailer.

 

5th prong usually is for brake release while backing up.
With my F450 I was backing up those with no 5th pin just fine.
Older trucks don't have backup light connected to the plug and I would have my doubts 2010 does.

 

I have a 2" drop on my 2004 completely stock truck for my cargo trailer, I second the adapter 5 to 7

 

Yep get the 7 to 5 adapter. My dad's boat has 5 pins, we just leave it attached to the trailer all the time.

 

Thanks guys I will get the 7 to 5 pin adapter...Don't know why I didn't think of that, Somehow my head was wrapped around the four changing to 5.

 

And again, make sure you have the backup light connected to 7 pins. Otherwise the adapter will do absolutely nothing.

 

Ford trucks as early as 94 (my brothers) and 96 (my Dad's) had the 7 pin wired for backup lights. Every one I've seen since that had a 7 pin was wired the same. It's a standard and I'm sure they've done it since they put 7 pins on at the factory.

There was a period in early 2000 or around there where some towing relays and fuses were in a bag in the glove box, instead of in the fuse/relay boxes, but as far as I know, this was only a couple years.

 

Bought the adapter (7 pin to 4 or 5 pin) today at Tractor supply, threw in the the ball also:

Out the door for a buck seventy!!

 

Aren't you missing zeros before decimal point?
Evan adapter can be found cheap, the 10,000 hitches are not cheap.
How it works?

 

Not sure what you're saying...Here's a link.

The adapter was twenty.

add tax and you're out the door for 170!!!
