Video Transcript for Trailer Wiring Harness Installation - 2013 Chevrolet Silverado

Today in our 2013 Chevy Silverado, well be installing the Hopkins Endurance 6-Pole Trailer Connector Socket part number HM48420. This will be in conjunction with the Pollak 5th Wheel and Goose Neck Trailer Connector Wiring Harness part number PK11932. To begin our install, well take our Hopkins 6-Pole and make sure we have a hole saw large enough so that the 6-Pole can be mounted in our bedside. Were going to mount it about right here, so well go ahead and take our hole saw and drill a hole in the bed liner and side. Now we can take our wiring harness and feed it from underneath up and out the free drilled hole. Once we feed it through, well go ahead and pull it out so we can work with the end. Typically we would install a seven blade end that would connect to this wiring harness, but because we need a 6-pole trailer connector to connect to our trailer end, were going to go ahead and remove each one of these connectors.

The yellow wire will not get used at all. Well go ahead and cut off the ends. Well then go ahead and remove some of the wire loom to give us a little more working room. Ill simply take my utility knife and cut off some of the wire loom. Ill go ahead and take the yellow wire and run it back into the wire loom as it will not be used for this application, then well strip back our wires. Next well take the connector and feed the wires through it.

Well go ahead and loosen this set screw on the top connection which would also be TL for taillight. Well take our brown wire, put it into the connector and then tighten down the set screw to hold it in place. Well go clockwise around our connector, loosening the set screws, installing the wires and then securing them with the set screw. Next, its marked as AX/EB for the electrical brake connection point. Our wiring harness, that will be the blue wire. The next connection is marked RT for right turn signal will be the green wire.

Then well have LT for left turn signal will be our red wire. The center post will be for the black wire which is power to our trailer. Then we have GD for ground that will be our white wire. This ground wire is a little bit larger than our connector will allow for so were just going to trim off just enough wire to get it into the connector. Once we have it in, well tighten it down. Now once we have all the wires installed, tightened down and secured, we can wrap it up with some black electrical and then install the cover.

Well lock the connector in place and tighten down the set screw then well go ahead and finish wrapping up our wires with a black electrical tape. Once weve got it wrapped up, were ready to install it. We can secure it here directly to the bedside with some long self-tapping screws to go all the way through the bed liner into the sheath metal of the bedside. Take the wiring harness, feed it up over the frame and follow the manufacturers wiring down behind the bumper. Here behind the bumper, we can locate the manufacturers electrical connector going to the manufacturers seven blade. To remove it, well release the locking tab on it, a little easier with a flat blade screwdriver and gently prying out. Press on it releasing the connector from the back of the 7-pole. Next, well take the new wiring harness, plug directly into the manufacturers wiring, firmly pressing it together and reconnecting the connector lock. Well take the other end of our wiring harness and replace the manufacturers connector in the back of the 7-Pole, plugging in line with the manufacturers wiring, well firmly press it in place, lock it in position and then push on the connector lock. Then once we have it all connected, well go ahead and secure it with some black zip ties as necessary. Now that we have the wiring secured, well go ahead and cut off the excess zip ties to clean up our install look. That completes the install of the Hopkins Endurance 6-Pole Trailer Connector Socket part number HM48420 in conjunction with the Pollak 5th Wheel and Goose Neck Trailer Connector part number PK11932 on our 2013 Chevy Silverado. .

This heavy-duty trailer connector socket has an outlet for a 6-way plug. A weatherproof, insulated lid covers the terminals. The cover is also easy to open and extra-durable.


Very difficult to make the wiring connections, I was afraid I’d have problems on down the road so, I took it out of circuit and threw it away


Worked for me. I used the six wire even though I only hooked up 4 for the toad. The RV 7 blade allowed me to bring a power lead to the toad if I ever need it for charging or power the Aux Brake unit. The bracket could be rotated in any direction and I found the best way was to rotate 90 degrees and install to the base plate. My toad grill made for a tight fit for both break-a-way switch and light connector, but they fit side by side with the addition of an L bracket for the break-a-way. The wiring connections seemed solid and water tight. Wired correct 1st time, No Problems.

Still good after a year of use.


This was an exact replacement for another connector that had been damaged. Simple and easy to change out.



Connector still works fine. Haven’t had any problems.


Yes I use it from my motorhome to the jeep I tow and to the trailers.


I installed this product on a 2016 Cherokee. I followed the instruction video pretty much exactly. However, I realized it had a tendency to push in and out when plugging in the cable. I zip-tied the bottom of the bracket to the car grill and that stopped the bracket from moving.
Great product. I haven't had any issues with it since installation.


I have made purchases for two different vehicles. Both were used for four wheel down towing. Each time etrailer gave me correct information on the products and promptly shipped and delivered them. Best of all they fit correctly and no surprises. I will use them again.

Rick I.


thank you for touching base with me. All the products seem to be fine.They are in use


Very heavy duty, well built. Simple instill, all parts needed & good instructions for wiring

Walter K.


still working great after one year on my toad vehicle.


It was exactly like I expected and etrailer's service was fantastic. I THOUGHT I had ordered it but it never showed up (I probably forgot to push the "enter order" button. Anyway, I called them and spoke to Jesse. He went out of his way to make sure the order had not been entered, then entered it for me and followed up to make sure I got it. Thanks, Jesse!


This product was exactly what I needed to complete the wiring connections between the RV and Jeep Wrangler. Comes with easy instructions and mounting hardware.


Great product! is great to do business with. Responsive and very fast to deliver!



One year later and this is still working great!


I've ordered from etrailer previously and have always gotten good service at good prices. Very satisfied, once again. I also appreciate the videos that etrailer provides as assistance for those of us who always need assistance! I'm sure I'll be back again when I need rv parts.


Worked as expected!

Easy to install
wires and by using the included bracket, had no problem at all installing it on the front of my TOAD (2012 Ford Fiesta)


Perfect for the application used on my ATV and holding up well


Installing was a bit of challenge finding a good place/method.
It has worked fine since installed. My vehicle is a 2019 Chevy Colorado.


Very good design and easy to install; best suited for 14 AGW.


This is a replacement for one I caught on something and broke. It is installed and working great. I have it on my Goldwing trike. It is the right size and works perfect. I love it.


Nice connector, came with everything needed to install.


Finally found a plug with a cable clamp...most don't have this! As always, eTrailer was easy to deal with, shipped quickly, and had fair prices.


The plug looks to be good quality but the bracket is cheap.


Have ordered a number of products from etrailer over the years and never been let down. Response has always been fast and of great quality.
Thanks etrailer!


At last I now have a solid connection at the towed vehicle connection. Thank You etrailer.


Easy to hook up, works as shown, perfect for what I needed

Don S.


Works great


Easy for one person to install. Quality product


Looks good will install this over the week end if it’s not too cold


Good solid product for a very reasonable price. Now I can use my old wiring with my new vehicle.

  • Connecting 6-way Vehicle Side And Trailer Side Wiring
    For your 6-way connection on your tow vehicle and your motorhome, you will want to make sure they match the attached photo. The vehicle side is labeled in the photo as is the trailer side. I gave you views from either side of each adapter. This will give you the standard 6 way wiring so your vehicle and your trailer will be compatible with other 6-way systems.

  • 6-Way Trailer Connector Availability for a 2006 Chevy Silverado
    It sounds like you are looking for a 6-way vehicle-side trailer connector. For that we have the part # HM48420. I attached an install video that shows the connector being installed in a similar 2013 Chevy Silverado as your 2006 model.

  • How to Wire a 6-Pole Trailer Connector
    I have attached a photo of the common functions for a 6-pole trailer connector for you. If you are looking to replace or add a connector to your vehicle/trailer then you can use part # H20036 for the male (trailer) end and part # HM48420 for the female (vehicle) end. If you will be using existing wires to attach to either of these connectors then it is always a good idea to test them for function using part # ALL640595 first.

  • Replacing 7-Way Trailer Connector with Smaller Connector to Tow a Trailer with Brakes
    A 6-way round trailer connector, like # HM48420, once it's mounted isn't going to be much smaller than a 7-way. If you don't need any functions other than running, brake, and turn lights along with the brake circuit I suggest going with a 5-way flat connector like # HM47900. To put a 5-way on both your tow vehicle and trailer you can use the kit # HM47890 that includes both connectors.

  • Recommended 6 Way Trailer End Connector / Conector De Remolque De 6 Pines Recomendado
    For the trailer side, you will need the 6-Way Molded Connector with Cable # 50-61-108. This will measure 8 feet long and will be more heavy duty than some of the other options we have. I know you mentioned already having the 6 Way on your 2020 Chevy Colorado, but if you want another good option for this, the Hopkins # HM48420. This another heavy duty option and will match the trailer end perfectly. Para el lado del remolque, necesitará el conector moldeado de 6 vías con cable # 50-61-108....

  • Tow Bar Diodes for 2015 GMC Terrain with Sockets and Umbilical Adapter Present
    Based on your pictures it looks like your tow vehicle has a 7-way pin style connector and the wiring you currently have is a coiled 6-way round to 4-way round. Also looks like you have a socket already that could be wired as well. The 7-way round style connector that you have is not a standard RV style blade 7-way. There's no easy way to use what you have since the sockets your RV has aren't standard so your best option would be to replace or add a 6-way round socket like # HM48420 so...

  • Will the Hopkins 6-Way Trailer Connector Work With the Hopkins Endurance 6-Way Socket
    The Hopkins Trailer Connector, # H20036, will work with the Hopkins Endurance 6-Way Socket, # HM48420. One thing to keep in mind when using these two items is to make sure that you wire the Endurance socket so that it is compatible with the 6-way trailer connector. There are two different ways to wire a 6-way trailer connector and the main difference is the location of the brake control wire and the 12 volt power wire. I have attached a photo that shows how you should wire the Endurance...

    There are a few different options for you so that the 6-Way Molded Connector with Cable # 50-61-108 is compatible with a connector on your tow vehicle. If you already have a 7-Way connector on your tow vehicle you can simply use the Hopkins Endurance Multi-Tow Trailer Connector Adapter # HM47570 which will convert your 7-Way to a 6-Way with the option to connect a 5-Way or 4-Way without an adapter as well.

  • Availability of Mounting Bracket for Bargman 6-Way Super Sealed Connector with Cable # 50-86-007
    The Bargman 6-Way Super Sealed Connector with Cable that you referenced, part # 50-86-007, includes two integrated mounting tabs, one on either side of the 6-way round connector. No bracket is required, although you do need to supply two screws to attach the connector at the rear of your tow vehicle. I did try a test-fit of this harness with several of the brackets we offer but none will accommodate the size of the cable housing. If you prefer to have your 6-way bracket-mounted you could...

You will need a plug like the Hopkins Endurance 6-Way Trailer Connector Socket - Vehicle End - Ergonomic Design, # HM48420, installed on your 2003 Chevy Tracker.

  • What Gauge Wire will Fit Into a Vehicle Side 6-pole Round Trailer Connector
    Both the Hopkins # HM48420 and the Pollack # PK11609 will accept a maximum of 12 gauge wire, so neither will accommodate 10 gauge. To get aux power and ground to your 6-way, you will want to run a length of 12 gauge wire like our 12 Gauge Primary Wire # 12-1-1 or # 12-2-1.

  • Wiring a 2009 Scion xB to Tow an Aspen Trailer with 6-Way Connector and Separate Turn/Brake Lights
    First, you will need to add a 4-Way trailer wiring harness on the 2009 Scion xB. You can use # 118468, that you have referenced. The rest of the installation will require a little hardwiring since trailers towed by passenger vehicles normally have combined stop and turn signals. What you will need to do is cut off the 4-Way plug after installing the wiring harness on the vehicle. This will leave you with a white wire, a brown wire, a green wire, and a yellow wire. You will need to use...

  • Can 6-Way Connector with Separate Brake Light and Turn Signal Circuits Install on 2013 Ford Focus
    A 6-Way round connector, especially one that has separate brake light and turn signal circuits, is rare which is why you can't find one. But I can tell you how to make your own 6-Way with separate brake/turn circuits. First, you could get some 6-Wire jacketed wire, # DW04906-1 sold by the foot, and a 6-Way round vehicle side connector such as # HM48420. Then you would use a circuit tester such as # 40376 to find the functions of the taillight wires on your 2013 Ford Focus. Once you have...

This combination will work well with the Roadmaster Nighthawk All Terrain Tow Bar w/ LED Lights # RM-676. Then you will need a wiring kit for your Jeep. I recommend the portions of the Roadmaster wiring kit # RM-15267 that aren't already integrated into your tow bar. These parts are female spade # RM-300115-00, 3 feet wire loom # 459075-1, 30...
