A wiring question

kgornek · September 18, 2003

Hey all, quick question.

I have the tow package on my truck and it includes that plug in connector for the trailor wiring. I'm going to tow a Uhaul trailor in a few weeks and was wondering if I could purchase something that would plug into that and convert the leads to the type used by Uhaul. I'm sure you all have seem 'em. The Y (male) looking pig tails....

Any advice or good places to purchase would be appreciated.

Thanks!

Walmart sells them I think something like $10 or so.

Most Uhaul places sell the connector you are talking about. That's where I got mine.

I have one from U-Haul laying around somewhere too...

You need a round 7 way BARGMAN to a flat 4 blade adapter

U-haul has them

Walmart may have them

Any Trailer / RV store will have them

Here are a few part numbers:

Pollak (mfg) 12-713

Jeep Chrysler: 56019824 (yep, same thing came w/ my Jeep Grand cherokee Tow Pkg and will work in any 7 way Bargman connector)

You will probably need a round 7 wire to a flat 4 wire and then a special 4 wire that splits a right turn, left turn and two running lights. Years ago I bought one that did that. The UHaul trailers used to have two sets of wires that needed to be plugged in. One set was left turn/stop & left running light and the other set was right turn/stop and right running light. I don't know if UHaul has changed their wiring configuration or not. I'm sure the UHaul dealer has the pieces to make the conversion without any problems.

For some reason when I towed a trailer from U-Haul the 7-4 way adapter that I had bought at a local auto parts store would not work I had to buy an adapter from U-haul to make it work with there trailers. I can't remember what it was that made me by the different one. I would make sure you look into that before you end up having to get two.

The last time I rented a trailer from U-Haul (thier smallest enclosed trailer), I just needed my round 7 pin to flat 4 pin converter. Their trailer plugged right into that. The time before that when I used one of their car dollies,, I needed the above conveter plus a U-haul converter to go from the flat 4 pin to pig-tail leads. I already had that - had bought it years ago from U-Haul. Their trailers seem to have some really cobbled up wiring these days.

They try to make the plugs the most non-standard as possible. Selling those pigtail hookups is a huge money maker for them.

LARSONEM · September 18, 2003

Years ago when UHaul had the individual wires to hook up they opened your car trunk and plugged them into the back side of the tail light sockets. That's back when you used to rent the hitch from UHaul too and hook it on your bumper. That's in the days long long before everybody drove a truck, suv or van that came from the factory with a class III hitch and wiring plug already on the back!

Hmmm, sounds simple but yet confusing! LOL

I hate buying anything from U-haul because they over charge you for that stuff. But I guess I'll have to bite the bullet if need be. But, if anyone would have any links to buy these online, I sure would appreciate it.

Thanks for all the input!

Is this what I need?

U-haul Store

Depending on what your 7 way plug on your truck looks like, I was thinking more along the lines of this one. Its a typical 7 way "RV" plug to 4 flat adapter.

U-haul Store

When I had to use there car trailer this is the one that I had to get.

I just rented a car trailer from Uhaul a few weekends ago. I already had a round 7-to-flat 4 adapter and then I bought an adapter for the flat 4 to the Uhaul trailer. This was cheaper than buying a round7-to-"Hhaul" adapter.

I'd recommend buying a good round 7-to-flat 4 adapter, as this will give you what you need for most towing applications. Then just buy a flat 4-to-"Uhaul" adapter for your rented trailer (they one I bought was only about $4).
