Quick shipping, will order from them ag ain!

Exactly what I needed and It's a great fit



by:

Very Nice Rugged piece. Thanks much!



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.

Have no issues since the connector plugs replaced. Very satisfied.

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:

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



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

No problems. Working as designed.

well made, delivered quick



by:

used to replace pollak trailer hookup that lasted over 25 years



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.



by:

Great product just what I need thank



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:

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:

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:

Purchased some new LED lights for trailer. eTrailer has good prices and a good selection. Shipping was a bit slow but that may be be eTrailer's fault, we all know how the postal service works...or doesn't.

No reservations about re-ordering from this company, I like that George followed up with me afterward to make sure I'm satisfied.

Order with confidence!



by:

Great price.



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.



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:

Was impressed with the websites videos showing how to remove, replace and wire these fittings. When the fitting arrived the procedures were as easy as demonstrated. Did note however that the old fittings showed silicone sealant around the wire connection points and don't recall that being part of the instructions, but seemingly a good idea



by:

This item and the receiver were exactly what I was searching for. I have a motorcycle trike, with a matching motorcycle tow trailer. That is what these items were ordered for. Very happy with purchase and shipping.



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.



by:

I received the plug/receptacle for my 2002 Chevy van promptly and it was the right fit. The videos provided on the site were very helpful in wiring the plug correctly. All-n-all, a great experience and I would recommend E-Trailer to anyone.



by:

The Pollak quality is always great! I use this style plug for my trailers. They last longer than the cheap rubber plugs and are easy to maintain.



by:

It works as expected and a good as my old one. It fits a little tight into the female receptacle. At first I thought it was not going to work.

  • 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....

  • Which Pin of 6-Way Round Carries 12 Volt Accessory Circuit
    Yes, on a standard 6-way plug the center pin is the 12 volt accessory circuit. I attached a picture of a 6-way wiring diagram for you to check out as well.

  • Parts Needed For Connecting 6-Pin Vehicle Connector To 7-Pin Trailer Connector
    I have included images for the wiring of a 6-Pin and 7-Pin trailer connector. The 7-pin has separate turn signal and brake light wires than on a 6-pin where these wires are combined. I know you said that you have already converted your vehicle end to a 7-pin but the easiest solution would be to convert the trailer to a 6-Pin with a new Connector # PK11604. This will mean combining the tail light wiring to operate as turn signals and brake lights. If you wish to keep the 7-pin connector...

  • What are the Functions of the Wires on a Gooseneck Trailer with 7 Wires
    There isn't a standard for trailer wiring color but the likely functions of those wires are red for left turn/brake lights, yellow for reverse lights, brown for right turn and brake lights, green for running lights, black for 12 volt power, blue for output to trailer brakes, and white for ground. On the trailer side you could either trace each wire back to determine the function of each or you could use a separate 12 volt battery and connect each wire, one at a time, to the positive terminal...

  • How to Wire 4 Trailer Wires Into the Pollak 6-Pole Trailer Connector
    Typically, the wire colors are brown for running lights, green for right turn and brake lights, and yellow for left turn and brake lights. White is ground. To confirm this on a trailer you can trace the wires back to see where they terminate or take a separate 12 volt battery and use it to power each wire to see what lights up. To wire up the 6-Way # PK11604 with the 4 wires if looking at the back of the 6-Way where the wires attach running lights will be in the 12 oclock position, ground...

  • Can a 2004 Subaru Outback be Flat Towed and Parts Needed to do so
    I looked up the online versions of the owner's manuals for your Forte and your Outback Wagon. It looks like the 2013 Kia Forte can be towed with a Tow Dolly but the 2004 Subaru Outback Wagon can be flat towed. You will want to verify this with your copies of the owner's manuals or local dealer. I couldn't find an online manual for your 1988 Dodge Dakota so you would need to look that up or contact your local dealer for info on that vehicle. If you let me know which of the 2 vehicles I...

  • 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.

  • Troubleshooting Brake Controller Output Pin of 7-Way on Vehicle that is Hot All the Time
    The brake controller output pin on a 7-way should not be hot all the time. The only pin that should be hot all the time is the 12 volt accessory circuit pin which is in the 1:00 position. The brake output pin is in the 5:00 position. Typically a short between these two circuits would be the reason the output pin is hot all the time.

  • Parts Needed to Add Charge Wire to Flat Towing Setup
    Roadmaster has two charge line kits for this situation where the battery needs to be charged. The part # RM-156-25 which was designed for supplying the towed vehicle with wiring for charging the battery and the part # RM-156-75 which is for creating the charge line on the tow vehicle side. If you have a 4-way setup you'd need to swap to a 6-way for the wiring so that you have enough circuits for the charge line. So for that you'd need the part # PK11604 and # PK11609.

  • Troubleshooting Running Light Malfunctions on a Kaufman Trailers Mini 5 Car Hauler
    If the other lights are working correctly, the most likely cause would be a bad ground. Ground issues may not be apparent until a larger load is placed on the circuit, like when the taillights are activated. It is also common for tilting, folding tongue trailers, and trailer with lots of moving components, like your car hauler to have grounding problems due to the moving components. These moving components, prevent full continuous contact of the metal surfaces, and interrupt the ground...

  • Parts Needed to Flat Tow a 2019 Mini Clubman w/Manual Transmission
    To flat tow any vehicle you would need a base plate kit, tow bar, safety cables, vehicle wiring, a supplemental braking system, and possibly a high-low adapter. Most of the equipment is generic but the base plate kit is specific. As of right now (January 2019) the only base plate kit that has been confirmed to fit a 2019 Mini Clubman is the Blue Ox # BX1315 and it is only compatible with S models of the Clubman.

The coiled cable will help to prevent the excess cord from dragging on the ground.

  • Which Pin on Trailer 6-Way Carries 12 Volt Accessory Circuit
    The center pin of a 6-way does carry the 12 volt accessory circuit like you described. The brake controller output circuit would then be the pin in the 10:00 position like what you see in the diagram attached. You should note that in some cases these two circuits are switched and are opposite of the diagram. Since this is a pretty common issue that frustrates people and you asked specifically about those two circuits on a 6-way I figured it was worth mentioning.

  • Towing a 2014 Chevrolet Spark Behind a Motorhome
    I did some research and found that your 2014 Chevrolet Spark with an automatic transmission cannot be flat-towed behind your motorhome. In order to tow your Spark you will need to either use a transport dolly or use a tow dolly. I recommend the RoadMaster Tow Dolly with Electric Brakes, part # RM-2050-1. This dolly has a capacity of 4,250 lbs and has electric brakes. This dolly also has an adjustable axle and ramps which will allow it to fit almost any vehicle. And the tow dolly also...

  • How to Install a Brake Controller on a Vehicle that has a Factory 4-Way
    The best way to install a brake controller like the Prodigy P2 part # 90885 on a vehicle like your 2001 Mercedes 320 that has a factory 4-way is to use the # ETBC7 that you purchased as well and install it according to the installation instructions by hardwiring everything. For your vehicle there isn't a simple plug-in adapter available so using the # ETBC7 would be your best option. I attached the installation instructions to the right plus an install video for you to check out.

The highest rated tow dolly that we have to offer is the Roadmaster Tow Dolly with Self-Steering Wheels and Electric Brakes # RM-2050-1 which is rated for 4,250 lbs.

Unfortunately, colors don't always correspond to the function you think they would.

It'll plug right in to your 6-way on your RV. If you sometimes tow the boat with a different vehicle and need to keep its 5-way then you can add a 6-way and have two connectors on it.

    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.
