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.

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.

Product did hot meet expectations. Had to revert to original plug-in. Hardware purchased incorrect size. Connection failed!

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.

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.

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!

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.

I have not actually used it yet. It looks mechanically good; but, the connector markings are hard to read. I went to Pollack's web site for clarification.

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

  • 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.

  • How to Rewire Trailer for 6 Way Connection with Separate Turn Signals and Brake Lights
    First you will want a new 6-way like the Hopkins 6-Way Molded Connector, # H20036. Installing the 6-way plug will be made easier by using a junction box such as # 38656. This box mounts to the trailer frame and serves as a connection point between the trailer's original wiring and the new 6-way. Also you will want some Deka jacketed 2 wire, 10 gauge, brake wire # 10-2-1 to run the brake output circuit from the junction box to the brake assemblies as well as some Deka 16-gauge bonded 4-wire...

  • What Function is Carried on Center Pin of 6-Way Round Trailer Connectors
    A 6-way round-pin trailer plug like Pollak # PK11604 has a center pin that can be wired in two ways. The most common function to be found on that center pin is 12V trailer power. This is a low-level maintenance charge that will maintain a charged trailer battery while you're driving. In other applications this center pin will carry the trailer brake signal from the brake controller mounted in the tow vehicle. Please refer to the linked photo that shows both inside and outside views...

  • Tekonsha Brake Controller # 90885-3015P Recommendation for a 2003 GMC Yukon XL
    It sounds like you are in need of a brake controller. You would not want full 12 volts getting applied to your trailer brakes at the exact moment you apply your Yukon brakes otherwise your trailer brakes would lock up every time you touched the brakes. The tow package that came with your 2003 GMC Yukon XL gives you most of the wiring for towing a trailer but will not give you everything you would need to appropriately apply the brakes that are on your trailer. For that you will need...

  • Diagram to Use When Wiring 7-way in Place of 6-Way on Horse Trailer
    Your best option is going to be to use the wiring diagram I attached for 6-ways to identify the functions of the wires from the picture you sent in and then wire them according to the labelled pins on the new 7-way similar to the # HM48502 and you'd be set. Use the set screw that you see in your picture as the "top" when comparing what you have to the wiring diagram. The center pin is the 12 volt circuit on the 6-way and if you have no use for it (it has nothing to do with brake controller)...

    Sounds like you have a 4-way connector at the rear of your 1999 Ford F-150 and are looking for a way to install a 6-way so that you can power the camper you have that has a Pollak 6-way like the part # PK11604. For an adapter you would want the part # 30637. This will plug into the 4-way and will convert the taillight signal to a 6-way. To activate the power circuit for the camper battery you will need to run the black wire from this adapter to the positive post of the truck battery...

  • How to Convert a Military Wired Trailer to a 6-way Civilian Trailer Connector
    I wish we had an adapter that would allow you to tow your military trailer with your vehicle that has a 6-way but we do not. What you could do is cut off the military connection and then wire up a 6-way in place of it. For that you would need a Pollak 6-Pole # PK11604 and taillight converter # 118158. Before you cut off the connector you will want to pick out the following wires from the back of the military connector and label them somehow. Masking tape and a marker would do well. J,...

  • Troubleshooting 6-way Trailer Connector on 1999 Ford F350 Flatbed Truck
    There are actually two different accepted methods of wiring a 6-way trailer connector. The center pin on a 6-way trailer connector usually carries the 12-volt accessory circuit that is used for any trailer mounted accessories that might need a power feed, although sometimes it can be wired so it carries the output voltage from the brake controller to the trailer brakes. If you take a look at the FAQ article I have linked you to, you can see a wiring diagram showing how a 6-way should...

  • Troubleshooting Trailer Light Running Light Circuit Not Functioning
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are...

  • Reading 12-Volts on 6-way Connector of Kaufman Tilt Bed Trailer
    Do you mean that you're using a circuit tester on your 6-way connector on the trailer (not the truck) and you're reading 12 volts on one of the pins? The only way that would happen would be if you had a battery mounted on the trailer. Typically, the battery is connected to the 12-volt supply circuit off the 6-way to receive a maintenance charge.

    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.

  • Installing a 7-Way Trailer Connector on a Trailer with 6 Wires
    You can certainly add a 7-way trailer connector to your trailer with 6 wires. You would simply have 1 pin on the 7-way connector that did not function. I recommend adding a 7-way molded trailer wire connector like part # H20046, and a junction box like part # 38656. We do this on all of our trailers and our customers trailers and it will make future wire maintenance much easier. I have attached an installation video of these two parts for you to check out.

    Sounds like your trailer wiring does not have a ground circuit for it's connector. The easy solution for that is to run a wire from the ground pin of the connector to the trailer's frame. Your trailer electronics should work a little better now as previous to this it was grounding through the ball mount.

  • Testing the Trailer Wires for Function Using a Circuit Tester on a Horse Trailer
    My suggestion is to test the wires for function with the trailer connected to the tow vehicle. You will need a circuit tester, like # 40376, or a multimeter if you have one. You can start with any function, but I recommend starting with the left turn signal. It would help to have someone sit in the tow vehicle and engage the functions while you test the wires on the trailer. With the left blinker on, probe the wires until you find the one that carries a signal in unison with the left...

    This sounds like the problem could be a short or possibly ground related but based on what you have said a ground is much less likely.

Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light.

    You have discovered the "dirty little secret" of trailer wiring: wire colors are not a consistent and reliable way to figure out what each one does!
