A wiring question

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!

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.

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!

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).

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
