Establish a secure electrical connection between your RV and towed vehicle with this 6-pole, round pin socket. Plastic socket has brass pins to ensure minimum voltage drop and a rubber boot to protect terminals from dust and moisture.

by:

This part is an exact replacement to the part that failed. The failure was caused by a poor installation which allowed the rubber boot to chaff on the truck frame. As it was an exact replacement installation was straight forward although I modified the mounting bracket to prevent a reoccurrence of the problem.

It has held up well no failures. However, when another component failed I had to re-wire the connector. The socket for the ground wire is too small for all the wires that need to attach to it.



by:

Decent enough plug. It was an easy install. I would have liked to have allen screws to get a good bite, but will check the connections after a use or two.



by:

These connectors were high quality by a known manufacturer. I could have bought them locally but I wouldn't have gotten the expert advice and detailed information that I was able to get from eTrailer!. I talked to several people and each one was very knowledgeable. When the parts arrived, it surprised me because they came so quickly! I would readily order from them again if I needed more trailer parts. I used these connectors to adapt a Minn-Kota trolling motor to my fishing kayak and have attached some pictures showing it installed.

Used on tow vehicle for hooking up wiring harness to motorhome

Easy Installation. Seems more durable with the new back-plate included in the hardware. However the Backplate had to be shaved with a rotary burr-bit a little to fit the back of the PollaK housing



by:

Easy install. Especially with the available videos



by:

SAME AS THE FIRST ONE

I found what I thought I needed on the website to prepare our car to be flat towed, but wanted to call to verify. After a short phone call, eTrailer saved me about $50 and got me the stuff I actually needed to get the job done! I won’t shop anywhere else!

Easiest company ever to order from. Very efficient.

Not what needed, but now I am stuck with it.

This was a replacement for a broken existing one so it worked out flawlessly.

I found out about etrailer on an installation video on YouTube and decided to give them a try. They had all the parts I was looking for with good prices. As a plus, their shipping is fast and I got my order in no time. I will definitely use them again for my RV parts needs.

All of the parts I bought are still functioning as they should and I am still happy with my purchase.

Working as it should. Excellent company to work with.

Was very pleased with the service and got the right product that I needed.



by:

Good advise, Ordered...delivered on time..the best



by:

What can I say? It does its job. I used a 6-pole connector so that I could wire in a battery charger for our toad. The awesome folks at etrailer.com had to send me a replacement because one of the "ears" cracked during shipping. I'm assuming that it got squashed between some heavy parts as it was only packaged in a plastic bag.



by:

great plug well made easy install
etrailer
and all the folks there are wonderful will recommend and buy from again
I have gotten several things from them already I am rigging up my new jku to be a toad behind my motor home.
everything from tow bar base plate and wiring has been just what they said it to be and very simple to save money and do it your self, I have lots of experience but seriously if you can change your own oil you can do this kind of work also.
AAAAAAA+

The item is exactly as described and exactly what i needed to make the repair. I love working with these guys as they are helpful, knowledgeable, and delivery is always very fast. They are my 'go to' for RV and auto parts.

It is still working perfectly. Thanks.

I searched around the web in search of a custom wiring hook up that would work with the existing wiring circuitry that was already in place on my old Dodge pickup. Just replacing the trailer socket was the answer to my problem. It was an easy process to wire in the new plug, at a very reasonable cost. It was also shipped to my home in several days.

As described, easy install and works

Wrong connector sent.

Hey Bryant. I am so sorry to hear that - I am sure that is frustrating to say the least! Let me make sure we have the right one being sent to you. Be on the lookout for an email!



by:

Very nice unit. Good instructions. I needed this plug to wire a brake buddy unit into a towed vehicle, and maintain the lighting. Works very well.



by:

Product arrived in a timely manner. It was as described (or even better), with apparent quality of material and construction. I would recommend this product to anyone needing to wire a 6-pin, vehicle-side connector.

Made it easy to wire my 2015 JK for towing. Installation instructions were simple and straightforward.

  • Adapter For 6-Pin Round Socket On Vehicle And Trailer With 4-Flat
    Hello Willy, thanks for reaching out. If what you have on your truck is a 6-pin round plug like part # # PK12720 (pictured below), you can use the adapter part # PK12717. This will plug in the 6-pin round plug and allow you to hook up the 4-flat plug on your trailer. If the plug on your truck is actually a standard 7-way (also pictured below), what you will need is the adapter # PK12716. Leave a reply below with any other questions or comments and I am happy to get back to you.

  • Parts Needed to Flat Tow 2022 Jeep Wrangler
    The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles. We don't have a kit that includes everything you'd need for your 2022 Jeep Wrangler but we can help piece it all together. For a base plate kit you'd want the part # RM-521453-5 which is a confirmed and would work great with the Nighthawk tow bar # RM-676. Then...

    Yes, you will be able to use your Blue Ox Tow Bar # BX7420 and Blue Ox Patriot Portable Braking System # BLU37TR on your 2023 Ford F-150. But you will need a 12 Volt Outlet Kit # RM-9332 to power the Patriot braking system as the factory 12 volt will not have power when being flat towed. You will need the Blue Ox Base Plate Kit # BLU33FR for your F-150 along with the necessary wiring components. A Charge Line Kit # RM-156-25 is needed as the battery will be drained by your F-150 and the...

  • 6-Pin Connector For Front Of Jeep Wrangler When Preparing For Flat Towing
    You will need the Pollak 6-Pole # PK12720 to replace the end on the Hopkins Custom Tail Light Wiring Kit # HM56200. You will cut off the 4-way end and connect the wires inside the 6-pin connector. We do have a Mounting Bracket # PK11771 which will make mounting the 6-pin on the front of your Jeep easier.

  • Parts Needed To Adapt From Roadmaster StowMaster Tow Bar To Non-Binding Motorhome Mounted Tow Bar

This will allow you to use tow bars like the Roadmaster Falcon All Terrain # RM-522 or our best selling Roadmaster Nighthawk # RM-676 tow bars. The Nighthawk comes with the wiring for a 6 Pin Connector # PK12720 you would need to install on our Jeep.

  • Can Hopkins HM56202 be Wired into 6-Way Connector on Front of Towed Vehicle
    Absolutely! We actually recommend doing this exact install a lot of the time. Using a 6-way, like part # PK12720 for an example, at the vehicle's front allows you to install additional wiring for a braking system or charge line but doing it this way makes it an easier install because the Hopkins # HM56202 is the easiest to install harness for your 2004 Jeep.

  • Wiring Harness to Install a p2 Trailer Brake Controller on a 2002 GMC Yukon Denali
    The P2, Prodigy 2, Tekonsha P2 or Prodigy 2 are all the same brake controller, # 90885. We usually just call it the P2. For your 2002 GMC Yukon Denali and the P2 brake controller you would need harness # 3025-P. It is possible that you have a 6-Way connector on your Yukon. A 6-Way will have round pins, like # PK12720. But you might actually have a 7-Way blade style, such as # PK11893 which has 6 outside pins and one center pin. Either set up does have a brake output circuit so the controller...

Then you can hook upMagnetic Tow Lights - Red LEDs - 4-Way Flat Connectors - 20' Long Harness # PE26UR directly to the 4 way flat provided on the adapter. These tow lights have a 20 foot long wiring harness; use 48" Long 4-Pole # HM47115 if you need 4 more feet of wiring. For the charge line going to the towed vehicle's battery, you...

  • How to Tow a Trailer Designed for a Harley Streetbike with a Vehicle with a 4-Way
    We have what you would need to make the adapter you would need, but we don't sell one ready to go. What you will first need is the # PK12720 for your trailer to plug into, next you will need a signal converter to take the combined signal of your Jeep's 4-way to the separate signal of your trailer. For that you would want the # C56196. Lastly, you would need # HM48110 for a 4-way to plug into the Jeep 4-way. When connecting the converter to the 4-way the wires will match up color for color,...

  • When Truck is Put in Reverse the Trailer Brakes Lock Up
    Are you certain that you have the 6-way connector, like part # PK12720 with the 6 round pins? Or do you have the 7-way connector like part # PK11893 that features 6 blade-type pins with one connector in the center? The two can sometimes be confused. There are two possible reasons why the brakes are locking up on the trailer. If you have a surge or hydraulic coupler on the trailer, such as those typically found on boat trailers, the hydraulic brakes will lock up when the vehicle reverses...

    It sounds like you need to go from the 6-Pole, Round Pin Connector # PK11604 to a 5-Pole, Round Pin Socket # PK11502. This would require making an adapter using the 6-Pole, Round Pin Socket # PK12720 and 5-Pole, Round Pin Connector # PK11501. If I have this backwards then just use the other parts listed above.

  • What Circuits do the 2 Wires on a Trailer Surge Brake Actuator Wire To
    Your surge brake setup has an electric lockout solenoid. Either one of the wires on your brake needs to run to the reverse light circuit on your trailer connector and the other wire needs to ground. Doesn't matter which you use as they are not polarity sensitive. On a 6-way the most likely pin to carry the reverse light circuit would be the center pin.

  • Using 12-Volt Accessory Feed From Trailer Connector to Maintain Battery on Pop-Up Trailer
    Typically, the blue wire on a 6-way connector is used to carry the output voltage from the brake controller. The 12-volt auxiliary feed, which usually feeds the center pin on the trailer connector can be used to maintain a fully charged battery, but will not have enough amperage to charge a dead battery.

    Replacing the wiring harness on your 1976 Jayco Eagle pop up trailer should be fairly easy.

This cable is 8' long and coiled to reduce the chances of it dragging on the ground between your motorhome and car being flat towed. You will not need any converters as your motorhome having a 7-way has already combined the turn signals and brake lights in the 7-way. The cord is held in place by the covers on the 7-Way # HM48470 and 6-Way...

    I think I can help you out here, but you would need to build the adapter as you have suggested. I do not know of a power supply connector assembly for a stand-alone battery at this time. I would start with an appropriate length of 10 gauge double bonded wire, # 10-2-1, to go from the 7-way or 6-way trailer connector to the area where the battery will be stored. Do not store the battery inside the horse trailer or directly on the ground. Next, wire a vehicle end connector that is compatible...

One option would be to use the Curt 6-Pole Square Trailer Wiring Connector Loop # C58034 and cut off the female end and install the Pollak 6-Pole, Round Pin # PK12720.
