Great Product. Just remember to order the boot for the back of it separate.

Awesome product selections and quick response towards shipping. Made me feel like I was actually getting somewhere. If you have a trailer, camper, or any type of tow behind application get HOOKED UP with this company. Very satisfied

I hook and unhook my trailer about twice a day as I need my truck for hauling stone and dirt. I have put this through the ringer. Still good as new...Happy customer



by:

I would highly recommend this. It is heavy duty and quality built. A great value for the money



by:

Excellent product! - have, over only a few years, steadily worked my way through progressively more durable trailer cable sockets. The last one was the Hopkins heavy-duty, or something to that effect. The plastic casing on it broke within three months. I'm really looking forward to putting these to the test - I'm a farrier - I pull a trailer every day; the traffic in this area means that I must rely on excellent contact between vehicle/trailer for turn / brake signals and functioning trailer brakes. Nothing less. These sockets are heavy, all-metal (zinc-coated - road salt shouldn't be a problem), with few / no seams. When the trailer end is plugged into the truck receiver - it's a nice tight fit, with no movement: it's locked in. There are only two drawbacks for the homeowner who is looking for the do-it-yourself package: if you are looking for a metal bracket that bolts underneath the truck bumper and holds this part - there isn't any. And no bolts, either. I don't know if they sell them for these - I didn't check. I simply manufactured my own. So far, I'm delighted with the product.



by:

I ordered the 7 pole socket (PK11720) and the rubber boot for it. (PK11761) Also a trailer end plug (PK11700) to fit into the socket. The items arrived on the exact estimated arrival date that I was given on the day of ordering.
Wiring the plug and the socket was very easy. Each terminal has a small screw that holds the end of the wire in place. It is a simple matter of threading the screw out, putting the wire in the hole, and then tightening the screw onto the wire.
The boot fits snugly onto the back of the socket.
I used these parts to repair the power cable assembly to a truck mounted forklift. The parts are exactly what was needed to replace what had been damaged. The quality is good and the prices are excellent. I will use etrailer.com in the future when I need related items. I am very pleased.



by:

This is much better than the OEM on my New Holland Tractor asit is made of metal. It also cost less than the all plastic replacement from the dealership. etrailer was fast with delivery. Thank you.

Performed as expected to date.



by:

Trailer plug works great.



by:

Bought to replace a 12 year old Pollak identical connector that I removed and could not re-use due to wire connections on the back being corroded (road salt area). The 12 year old connector worked fine except the flip up cover was a bit stiff. The 12 year old connector was also made in USA. The new connector I just received is made in China. From the price, I had hoped it was still made in USA. It seems that most of the time I am disappointed with the newer imported China versions of products once manufactured in USA. So my expectations for this product to have a long life are not very high.



by:

Well I have not installed it yet, but it is marked for each trailer wire by color, matching much earlier models. Did not come with mounting screws and nuts, but not a big deal.



by:

I could not find this style or make trailer plug in my local auto parts store. I got tired of trying to find it so I ordered it on line. etrailer was convenient and less expensive than any other website.



by:

The metal body and good quality pins and connections make this one the only one for a professional job.
Remember if you use dielectric grease and the rubber boot you'll never have corrosion in your connections . Dissimilar metals and weather are a bad combination.



by:

For me, and probably you, etrailer.com is a great place to shop/buy quality products. They give great follow up after ordering and fast shipping @ a fair price. I believe their service & pricing is unbeatable. I do shop for bargains & etrailer is @ the top of my list.



by:

Excellent product! I bought this to replace the old, brittle, and broken plastic trailer connector on my 1973 aluminum camper. The plastic one stood out against the aluminum which I didn't like. So, I'm excited how this will blend in and look more natural. Besides aesthetics, this very sturdy and ruggedly built. It will clearly outlast the camper, no doubt. Will definitely buy again if I find myself with a different camper in the future.



by:

Etrailer web site was easy to work with and outstanding communication with your orders. Package was also delivered earlier than expected. I would rank etrailer as A+



by:

Great construction of the product, durable enough to withstand harsh working conditions and "operators" I am using that term lightly due to the mishaps that occur on a regular basis at my location.



by:

I got exactly what I expected. Great customer service & follow through.

This is a quality socket that is being used to support electrical connections between my RV and toad. Its held up beautifully & I continue to be very pleased with it.

Very fast service AGAIN! Always my first choice when shopping for trailer parts.

This trailer lighting socket is excellent quality, and super fast shipping



by:

Best 7 pole connector out there!!!!



by:

Great, Fast, Knowledgable and Polite Service. Return policy is also terrific no questions asked. I will use e trailer again. Thank You
Ken



by:

No issues, all the hardware was correct and the item is still working.



by:

This connector is really nice and with the screw tightening wire connections that are on it, it will make the wiring a lot easier to do.

  • Installation Procedure and Recommended Brake Controller for 2016 Jeep Wrangler Unlimited
    I'd recommend you go with a proportional style controller like the Tekonsha Prodigy P2, part # 90885. A proportional controller has an internal sensor that determines how quickly the tow vehicle is braking and will send the appropriate amount of voltage to the trailer brakes so the trailer and tow vehicle stop at the same rate. This leads to safer, more predictable braking action. To install the controller, you'll need our Brake Controller Installation Kit, part # ETBC7. The kit contains...

    Since you've got a few questions in here, in order to make sure everything is addressed clearly I'm going to list the answers to each of your numbered questions below. 1) You can test the wires using a Circuit Tester kit like # PTW2993 to determine which is the cold wire. Since auto manufacturers don't have a standard color they all use, it's tough to determine what is what on some manufacturers. The only way to truly know which wire is which on your vehicle is to test for power when the...

The 7-way connector included in the kit is actually an adapter meant to be plugged into an existing 4-pole trailer connector, but the connector on the adapter could be cut off and directly wired to the existing wires you located near the spare tire.

  • Stoplight Circuit for Installing Brake Controller Location in 2009 Toyota Highlander Hybrid
    One of the wires on your 2009 Toyota Highlander Hybrid (should be the blue one) should have voltage when the brakes are applied only, but if for some reason that just isn't the case the next best place to find the stoplight circuit would be from the third brake power wire as it similarly only has voltage when the brakes are applied. That said, one of the red wires of the T-one trailer wiring kit you have installed on your Highlander also would carry just a stoplight circuit so that could...

    You aren't alone here! This is a very common issue that we get questions about quite regularly.

You can simply use a Firestone Fuse Circuit Tap Kit part # F2526 and connect it in the fuse box located in the driver's under hood area. You will use a grommet already in the firewall of your Express to pass the wire through and make you connection. I've included a video my buddy Rob...

    Normally you can find the brake light switch under the dashboard at the top of the brake pedal. There could be a number of wires attached to the switch so you can use a tester like part # PTW2993 to test the wires. Since the auto manufacturers can use different color wires it is always best to use a tester and check the wires for function and not color. You would need to find the wire that only shows power when the brake pedal is pressed. That would be the wore that gets attached to the...

  • Converting a Semi 7-Way Trailer Connector to an RV 7-Way Trailer Connector
    There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to # PK11720. And RV style 7-way uses blades, like # PK12706. We do not offer any pre-made adapters to make this conversion that will carry all of the electrical functions required by the RV. Another thing to be aware of is fifth wheel trailers use a combined wiring system where the brake lights and turn signals are on circuit. Your semi connector...

    A 7-pin connector on a Mack Tractor like you described would function a bit differently than a 7-way blade-style RV connector.

In order to combine those three signals onto two circuits, you'll need a taillight converter. There isn't an off-the-shelf adapter that'll do...

If you do have the round pins then you will need a trailer end 7-Pole round pin connector, # PK11700, and a 5-Way vehicle end, # HM47900. You would then just wire in the 5-Way wires to the 7-Pole round to match the functions used by the vehicle end connector. I have included a link to our wiring...
