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!



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.

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:

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.

just what i need for my blue ox connector to our motorhome.

Great Product. Fast Delivery. Great Ret ailer!

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.

This is EXACTLY what I was looking for, it is an exact replacement part. Etrailer was the only place I could find this part.
Thank you

I’ve made several purchases from this retailer. The quality of their products is top notch and the price is very competitive. EXCELLENT customer service. Stacey assIsted me with my latest order and she was professional, knowledgeable and courteous. It was a joy working with her.



by:

Great product. easy to install and adj ust



by:

Exactly what I was looking for. Well made and the best price I found for this item.



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+



by:

Easy to work with. Thanks



by:

Great place to order parts. Always have the items I need and always get them within 3 days. I am a repeat customer and the only place I will use.



by:

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.



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:

For the money, it is a good product. It would be even better if it had a rubber seal, but for the price, the quality is very good. etrailer is the best. Lightning fast shipping, and super great communication. I love ordering from etrailer.com.



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.



by:

looked good



by:

Part was exact replacement for the broken trailer electrical socket I needed, at a price lower than I expected. Vendor has a good catalog of just about anything I could need for my trailer and will be using eTrailer.com from now on.

  • 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.

  • Will 2 Ground Wires Fit Together Inside a 6-Pin Connector For Flat Towing a Vehicle?
    On a 6-Pole, Round Pin, Plastic Trailer Wiring Socket # PK12720 there is typically only enough room for one wire for each terminal to mount inside the stud. You can still splice both the ground wires together and run a single wire into the terminal on the connector.

  • 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.

  • 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...

  • Pollak 6-Pole Trailer Wiring Socket # PK12720 Recommendation for Flat Towing a 2011 Honda Fit
    I would recommend you remove the 4-wire flat plug and replace it with a Pollak 6-Pole, Round Pin, Plastic Trailer Wiring Socket, part # PK12720, like you mentioned. This way you would not have to use an adapter which would give you a cleaner install and give you one less component that could potentially fail on you. I attached an FAQ article on tow bar wiring below for you to check out also.

  • Connector Needed for 6-Way Wire to 4-Way Round Socket on Towed Vehicle
    The easiest and most cost-effective thing to do would be to install the Pollak 6-Pole, Round Pin, Plastic Trailer Wiring Socket # PK12720 on your vehicle that is being towed. Aside from that you would have to use a different cord like the Hopkins # HM47043 that goes from a 7-Way blade to a 4-Way round as there aren't any adapters.

  • 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.

    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 to Convert a 4-Way Flat Trailer Connector to a 6-Way Round on a 2008 Jeep Rubicon Unlmited
    We have a brake controller wiring kit, part # ETBC6, that will allow you to convert your 4-Way to a 6-Way round. This kit includes everything you need to convert your 4-Way and install a brake controller. You would connect your 4-Way to the 4-Way on the back of the ETBC6. Next you would ground the white wire. You would extend the blue wire up to the cab for the brake controller output. The red wire would then be connected to your reverse light circuit or run up to the battery for a 12V...

  • Replacement 6-Way for Tow Bar Lighting On Vehicle with Damaged 6-Way Cover
    I have a solution for you, but the part # BX84-0182 is not an electrical cover. It is for the latches of the tow bar. It sounds like you are looking for a replacement 6-way since the cover of your has been damaged. For that you would need the part # PK12720. Just the covers are not available for the 6-way.

  • Can a 1997 Ford Taurus be Flat Towed Behind a Motor Home
    I found an online copy of the owners manual from Ford for your 1997 Ford Taurus. It states that you can only flat tow with 4 wheels down for a maximum of 50 miles and at speeds no greater than 35 miles per hour. To tow the vehicle further and at higher speeds you would need to use a tow dolly. Please check your owners manual and/or contact a Ford dealer for more information. We do have a tow dolly that you can use. Take a look at Roadmaster tow dolly # RM-2050-1. This unit features lights,...

  • Availability Of A 6-Way Square Male To 6-Way Round Female Adapter
    I have an option for you, but there is not an adapter made to go between your 6-way square female end on your California Side Car and the round 6-way on your trailer. 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. This will require you to use a circuit tester like the # PTW2993 to confirm the functions of your 6-way square connector and match them to the functions of...

  • 7-Way Blade to 6-Way Round Coiled Cable For Connecting a Motorhome To a Flat Towed Vehicle
    The Hopkins Endurance Flex-Coil Trailer Connector Adapter # HM47053 has the 7-way blade connector on one end and 6-pin round connector on the other. 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...

  • How to Power a Separate Clearance Trailer Light
    Having to run a separate wire to power the collision avoidance light on your trailer will depend on how and when you want that light to illuminate. If you want that light to be on only when the running lights are on, then you would not have to run a separate wire. You could simply cut the wire at the 6-way trailer connector and splice it into the running light circuit. If you do not want the light on all the time and you want the ability to turn the light on and off as you please, then...

  • Recommended Parts to Make an 8 Foot Connection from Truck 7-Way to Truck Bed Camper 6-Way
    For the connection, I believe you are looking for an extension like the Hopkins Heavy-Duty, Coiled Trailer Connector Adapter - 7-Way to 6-Pole Round - Center Pin Brake # HM47085, but an 8 foot length versus 3 foot. For this, you will need to create a cable using the Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard # H20046 and the 6 way # PK12720. I've attached an article to assist with the connections.

    I believe you are looking for the Hopkins Endurance Flex-Coil Trailer Connector Adapter w/ Nite-Glow - 7-Way to 6-Pole - 8' Long, # HM47053. If you need a 6-way socket, I recommend the Pollak 6-Pole, Round Pin, Plastic Trailer Wiring Socket w/ Rubber Boot - Vehicle End, # PK12720. If you need a 7-way socket, I recommend the Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End, # PK11893.

    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. It gets confusing with these connectors since you have male connectors inside a female connector so you never really know which one they are referring too. You can use some of the...

    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...

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

    I am not sure if you need the replacement connector for the vehicle side of your 1995 Ford F-150 or if you need the trailer connector that would plug into the F-150, so I will give you some options for both of them. You can use a circuit tester like part # PTW2993 to check the wires by function when installing a connector. If the connector you need is on the vehicle side and you determine it is a 6-way, I recommend part # PK12720. This is a plastic 6-pole round pin socket that would be...

You will then need to install a male 4-way trailer connector like part # HM38168 on the trailer that will attach to the opposite end of the converter box. In order to make these connections I recommend using part # DW05744-10. In order to allow for the 6-way trailer...
