The person who helped me find the correct part went above and beyond just taking my order and helping me find the correct part. Now I know why my dad suggested that I try etrailer to find the part I needed.



by:

It’s nice to have an inexpensive replacement part rather than buying another whole harness!



by:

Easy to replace. Fast shipping! Thank y ou



by:

I got exactly what I ordered, two replacement cable plugs for my tow bar from car to tow vehicle. Package included easy to follow instructions for wiring connections. The cable package from the tow bar company is pretty pricey but these plugs and the existing cable to repair cost around $10.00. I will probably order two more to have as spares.

It does what it is supposed to. Good pr oduct.

Great Product, works well.

Quick shipping, will order from them ag ain!

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.



by:

Great service



by:

Decided to make a spare pushbutton controller for my dump trailer so I wanted a good 6-pin connector that matched what I had. This was exactly what I needed. Good quality. Quick delivery. Good price. Had one hiccup with my credit card, and CSR's contacted me asap and got it all straightened out in no time. Would definitely order from etrailer again.



by:

I replaced the connector ends on the cable that hooks from my motor home to my tow vehicle.
The PK11604 are better made product than the original connectors. A machine screw is used to hold the
Receptial in place as compared to the original which had a flush head wood screw. The terminal hold down screws are stronger and easy to work with when installing the wires.





by:

Received quickly. Easy replacement for my motorhome teather. Well made.

No problems. Working as designed.

Works great, what I needed for the connection for my DC fuel pump to my fuel tank I carry in the bed of my truck. I have been a customer for a couple of years now and will continue to be as you always have everything I need then ship it out in a very timely matter.



by:

Shipping faster than expected. Price very good. Great customer service. Good follow up after sale with installation videos.



by:

I ordered replacement side markers and was pleased to find the bulbs came sealed to the lense. The ones they replaced had twist in bulbs that would work out of the back of the lense. Better than expected product and prompt shipping. Thanks, Jim D.

This works well. I used it for a couple of years and never had a problem.

I made some changes that required a 7 pin connector and removed this 6 pin for possible use later on.



by:

This electrical plug is everything that etrailer says it is - great product!



by:

these are just what need, I just got them in the mail about 30 min ago, could not find both parts at local farm store. these look like what I used when I was younger, they worked great then so should be good now. I thought I had a problem, but it was just me. Steve

Exactly what I needed and It's a great fit

used to replace pollak trailer hookup that lasted over 25 years



by:

well made, delivered quick



by:

Very Nice Rugged piece. Thanks much!



by:

I really appreciated the detail etrailer.com provided with each of their products. I was confident of what I was buying and that it would do what I needed to do. I will definitely be buying from them again in the future. Shipping was fair priced and very quick! Thanks a bunch, etrailer.com!! - Ryan



by:

This connector was used to replace a similar no name Chinese knock-off that had corroded badly. Also, I no longer keep the trailer cable connected and left in the elements. Easy to disconnect both ends and store separately.

  • Parts Needed To Connect a 5-Pin To a 6-Pin Trailer Connector
    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...

  • Parts Needed to Adapt 7-Way Combined Vehicle Wiring with Separate 6-Pole Trailer Wiring
    The easiest way to connect an RV 7-way with combined stop/turn signals to a 6-pole trailer with separate stop and turn lights is to use a converter like # 118158. This takes in the combined stop/turn signal and splits it out into separate signals for stop lights (the red wire) and for turn lights (the green and yellow wires). This is made easier by using a junction box like # HS381-9000 which provides both a place for making the trailer wiring connections and for housing the converter....

  • Wire Missing For 7-Way Trailer Side Connector
    I have attached the wiring diagrams for the different 7-way connectors used on trailers. I find it best to not reference wiring by color but instead function since depending on who made the wiring harness and who wired the trailer they can vary. As the white wire is typical of a ground connection the person who wired the trailer the first time may have not used it hoping that the ball connection would provide the ground that they needed to the vehicle. You may need to replace the 7-way...

  • How to Make 6-Way to 4-Way Coiled Adapter for Flat Towing Vehicle
    Since there isn't a 6-way to 4-way coiled adapter like you are looking for you'd have to piece together the kit you are in need of with the part # PK11604 for the 6-way, the part # RM-1064-B for the coiled wire section, and then for the 4-way part # HM48030 and you'd be set.

  • Solution for Connecting 6-Way Round on Towed Jeep to 4-Way Round on RV
    For your particular setup there isn't a single adapter available so your best option is going to be to just make your own using the Roadmaster 4-Wire Flexo-Coil Cord # RM-1064-B. This expands to over 8 feet to reach the distance between the RV and your Jeep and you can splice a 4-Round # PK11410 at one end and a 6-Round # PK11604 at the other to create the harness you need. This will give you a nice clean setup where you don't have to worry about connecting a bunch of adapter each time...

  • Options for 7-Way to 6-Way Adapter
    The Hopkins 6 Pole to 7 Pole Adapter, # 47435, does have a pin for the brake output for a brake controller. This adapter will work for your set up as long as the center pin of the 6-way plug on your RV is for 12v power and the pin in the 10 o clock position is for the brakes. You can verify this using a circuit tester like part # 3808. If the center pin on your 6-way plug is wired for brakes and the pin in the 10 o clock position is for 12v power, then you can still make an adapter using...

    I have a couple options as there is not one adapter from a 6-pin round vehicle connector to a 7-pin round commercial trailer connector. The first will combine a Adapter 6-Pole to 7-Pole Trailer Wiring Adapter # 47435 and a Pollak Trailer Connector Adapter # PK12727 to adapt your connections. Or you can wire in a Pollak 6-Pole, Round Pin, Trailer Wiring Connector # PK11604 to a Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720.

  • Parts Needed to Make a Taillight Signal Converter to Go From 6-Way Separate to 4-Way Combined
    Since your tow vehicle has separate turn signals and it sounds like your trailer has combined signals you will need to use an converter like the # RM-732. Sounds like your trailer has a 4-way on it and your trike has a round 6-way, so to make an adapter you will need a part # C58044 and a # PK11604 as well. You will want to determine the pin outs of the 6-way of your trike so you know how to wire up the # PK11604. Use a circuit tester like part # PTW2993 for this. You will want to wire...

  • Making 7-Way to 6-Way Coiled Adapter with Alternate Pin Out
    Best option would be the Bargman 7-way part # WG54006-046 which has a molded 7-way on one end and then unconnected wires on the other. You could then wire this to the part # PK11604 based on the pinout that you need.

  • Recommended Tow Dolly for 2016 Kia Soul Behind Motorhome
    Your 2016 Kia Soul with Sportmatic automatic transmission can be towed on either of the two Roadmaster Tow Dollys we carry as long as you have the 16 inch wheels. The 17 or 18 inch wheels will not work. The factory 205/60-16 tires will work well on the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 The tow dolly option comes wired but needs the connection like # PK12706 for a 7-way for most applications or # PK11604 if you have the less common 6-way.

  • What is the Mounting Hole Spacing for Pollak Vehicle Side 6-Pole Trailer Connector
    I went out to the warehouse and pulled Pollak 6-pole vehicle side connector # PK11608 to measure the mounting hole spacing for you. The holes are 2-3/4 inches apart on center. The vehicle and trailer side connectors are different. The trailer side that would plug in is # PK11604. But in a flat towing set up (towing a vehicle behind a motor home) the vehicle side connector would be at the front of the towed vehicle. The replacement Blue Ox model is # BLU43XR.

  • Fit of Hopkins 6-way Square to 6-Way Adapter # HM47415 on Coleman Pop-Up Camper
    Coleman used their own proprietary 6-way square connector, and from what I understand, it was only available from them. My contact at Hopkins tells me that the # HM47415 you referred to is different enough that it will not work. Since Coleman no longer manufactures campers, I am not sure where you would get an adapter. Your best bet would be to remove the existing connector on the camper and install a 6-way female connector like part # PK11604 (or whichever plug would be compatible with...

  • Troubleshooting Gooseneck Trailer Brakes that Lock Up When Using 6-Way
    The issue is that there are two ways that a 6-way is typically wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are swapped. Anytime we see trailer brakes immediately locking up when connected and there's a 6-way involved this is the issue. What you need to do is swap the two circuits on the 6-way adapter or the 6-way connector and you'll be good.

  • Troubleshooting a 6-Way Trailer Connector Install
    By looking at the picture you sent me it looks like the yellow wire is the left turn, the green is the right turn, the brown is tail lights and the white is the ground. Which leaves us with the two black wires. There are a couple options for determining what the black wires are for. You could get a 12 volt battery like a car battery and run a jumper wire from there to black wires to see what functions on the trailer activate. Or, you could trace the wires back to see where they terminate. One...

    I have attached a photo that shows how the Pollak 6-Pole Round Pin Trailer Wiring Connector part # PK11604 will need to be wired. In order to make sure that you are installing the correct wires into the correct pins you will want to use a separate battery and power each of the lights on the trailer's wiring harness while checking for continuity with a circuit tester like part # ALL640595. This will also allow you to see if power is not going through the wires that lead to the taillights....

You will have two wires coming off of each brake magnet on the trailer and you will need to ground one wire on each side and splice the other wire on each side to each other and another wire, spliced to these two, will go to the brake connection inside the 6-way connector, item # PK11604.

  • Can a Vehicle Side Trailer Connector be Mounted so that it is Facing the Ground
    If the vehicle side trailer connector is pointed towards the ground then what can happen is the increased likelihood of debris and moisture getting into the connector leading to corrosion and malfunction of the connector. Also, when a trailer is connected, the ground clearance will be reduced and could result in damage to the trailer side connector or the wiring leading to it.

  • Installing 7-Way Trailer Connector in Bed of 2006 Chevy Silverado 2500
    Assuming that the 7-way on the bumper is from the factory and the tow package harness can be unplugged from the rear of the connector, using a T-connector like # 41157 is what I'd recommend. Simply temporarily unplug the connection at the rear of the factory 7-way and plug the # 41157 inline as shown in the linked video.

  • Functions of 4-Way Wiring on Trailer and Vehicle
    The wiring on your car is going to match the standard 4-way functions by color. Green: Right turn/brake light Yellow: Left turn/brake light Brown: Tail/running lights White: Ground wire On the trailer side I wouldn't trust the wire colors. Unfortunately, colors don't always correspond to the function you think they would. The best thing to do is trace those back so you know what the function actually is and you can match that up on your trailer side connector.

    I checked out the owner's manual for your 2018 Ford Edge and it looks like you can flat tow most variations of the Edge but if you have the 2.0L EcoBoost with an automatic transmission (6F35) then you need to tow it using a dolly or with all 4 wheels off the ground. For the tow dolly option I recommend using the Roadmaster Tow Dolly # RM-2050-1 which has electric brakes. To activate the brakes you will also need a 6-Way connector like part # PK11604 or a 7-Way connector like part # PK12706....
