Video Transcript for Hopkins 7 Way Molded Trailer Wire Connector Installation

Today on our enclosed trailer we're going to be installing the Hopkins 7-way molded trailer wire connector, 6" long, part number H20044. Now to begin our install we'll go ahead and feed the wiring through the frame. Quick tech tip: to help feed the wire into place through the hole here in the body we're just going to go ahead and tape up our wires to help keep them together. Using some black electrical tape we're just going to go ahead and do a quick wrap-up of the wiring. Then we'll take the wire, feed it into place. Now we've moved to the inside. We need to find the 7-pole harness here inside the panel and pull it out when we have access to it.

There, now we have access to our y-pole wiring. We're going to add the Spectro trailer wiring junction box, part number 38656. Our junction box is going to get mounted to the wall so we can route the wiring into the junction box and make a nice clean connection point. I can go ahead and remove the electrical tape we put over our wiring. Now to mount the junction box I'm just going to use a couple self-tappers. To route into our box we can remove one of the plugs, install one of the grommets that has a pre-made hole in it, then put the grommet back into place.

You'll note that we left one wire out as it will get routed and directly connected to the break-away switch battery box. We'll go ahead and add our ring terminals here to our wiring. We'll go ahead and start making our connections with the junction box terminals. Note, they will not all match color for color. Here we have the blue wire that comes from our 7-pole harness, and it's going to go onto the blue terminal. It's also known as the hot lead for your trailer braking.

We'll take the black wire from the trailer side that runs back to the trailer braking and connect it to the same terminal. To secure it we'll use the star washer and nut provided. We'll just tighten it down hand tight this time. The next terminal over will say brown or running light circuit. For this one it will be our green wire and on the trailer side it will be our brown wire.

We'll move to the next terminal which will say green or right turn signal. For this one, coming from our 7-pole harness we'll have the brown wire, and from our trailer side it will be the green wire. The next terminal over will be left blank as it's not going to be hooked up. This would typically be for your yellow wire or reverse lights for a trailer. Since we're not using that in this application we're just going to dead-end the wire. Then we'll have the driver side turn signal. That will be the red wire from our harness and the red wire from our 7-pole connector. Then we're going to have the hot lead terminal. This is where you'll provide battery power coming from the vehicle to your trailer. That will be the black wire from our 7-pole connector and the black wire that will go to the interior lighting for the enclosed trailer. Then our final terminal here is going to be for the white or ground circuit. That will be the white wire coming from our 7-pole connector and the two white wires on our trailer side. Next we'll move to the outside of our trailer. We'll take the 7-pole wire that we brought it inside and we're going to secure it here to the trailer tongue using a Redline metal loom clamp, part number A0500. To secure the clamp we'll just use a self-tapping screw. There, now that we have it secured to hold it when we're not using it we'll just simply wrap it around the trailer jack. This will complete the install of the Hopkins 7-way molded trailer wiring connector, 6" long, part number H20044, on our enclosed trailer. .

7-Way Molded Trailer Wire Connector, 6' Long - H20044

i have been wiring 12 volt systems, hot rods, race cars, trailer of all types. although the plug worked like i wanted an this car trailer the color code reference chart is no way right. i did read this in the reviews before i bought it so i was ready for it. 652655

I felt the product was good, but the cord was not long enough. When I ordered it, the one I wanted had a longer cord, but was not available. I was in a bind so I took the shorter one. It works great, but it is not long enough for my needs. If I have to turn the trailer sharp the cord will pop out of the plug, due to the shortness of the cord. Good product. 339810


Comments

I sold the trailer. The cord was still not long enough.

The items that I orderd were received in a very timley manner. I had originally ordered a different trailer pig tail and etrailer contacted me and let me know that the items were back ordered from the supplier and made recomendations on what they had in stock. The staff at etailer are very proffesonal and I will diffenitly purchase from them in the future. 160503

The connector is a good piece, however the colors do not match up. Anyone familiar with trailer and truck wiring knows that the wires are all color coded for a reason. If your not going to make the colors match up then why utilize the same colors? I hard wired everything neatly and then found out brown doesn't go to brown, and so on.... Had to test every lead to get it all wired properly... extremely aggravating. My suggestion is that the wires be run properly so they can all match color wise... and if that's not possible, then send a wiring diagram along with the harness when it is shipped. 208164

Initially this product seemed perfect. It is stout and seems to be able to hold up to the wear and tear of the road. It fits far better then the cheap connector I picked up at the convenient store. The length was more than adequate to replace my old connector. However, after installing it my lights went CRAZY!! My passenger side turn signal was constantly on. When I hit the driver side turn signal all the lights flashed. The brakes did turn anything on. So I completely disconnected it and got out my trusted multimeter. Turns out that the brown wire went to the green on the trailer, the yellow to the brown, the green to the red, ect. It was a mess. Within 10 minutes I had the wires feeding the correct lights. I'm not sure if it is because Chevrolet doesn't use the industry standard or if my connector was defective. Either way it's fixed now and works great!! Even with all of those problems I still give it 4 stars. 245487

Good service. I had called and confirmed the details about the cord and plug. The salesperson was very helpful and gave me a good target date for delivery. Got it today as was promised. I’ve got it installed and it works well. It has a quality heavy duty cord that is molded into the plug. Time will tell if my hopes for longevity is achieved. Thanks and keep up the good service!! 666855

Built to last although I didn’t really get the chance to find out since I sold my boat 6 months after installation. But for those six months it performed great. The color code for the wires is not universal so Be smart with connections. 651278

My drum brakes locked up on me because it is a boat trailer and gets submerged in water. I hate drum brakes, due how many part are inside and can rust up. I am the 3rd owner of my 1998 boat trailer and it was hard to figure out what I needed to fix it. I contacted etrailer and they were super helpful, super informative and super easy to work with. I told them what I had, and what I wanted to do., and they put a package together for me and that was them. Everything was super east to install because it is all bolt on. I did have to do some cutting and grinding on my old tongue because the master was welded on. That was the only difficult part. My new setup is amazing and the disk brakes and new master make it feel like my boat is not even there. All in all, I am 110% satisfied and will definitely be a returning customer for any trailer needs. Thank you etrailer for making everything super easy. 635087

The color coding of the wiring in relation to their position was all incorrect to what is recognized as standard. Since the plug is molded there is no way to switch positions of the wires. I had to use a continuity tester to determine what was what. The trailer brake circuit was the only one that was correct 553914


Comments

There is more than one accepted color coding for a 7-way trailer connector, which is why we list the color code on the product description that shows which function each wire color carries. Heres a link to our Trailer Wiring help article that you might find helpful.

The wiring harness is a quality piece. It arrived quickly, and because all of the wires matched in color was a no-brainer to hook up. I've used it for over a year, and there have been no issues. It has a retainer notch that matches the retainer on the plug cover, and never detaches itself. 485013

Solid product made of good materials. Should last a long time and is a good replacement. Please be sure to watch the video as the cable colors are do not match up directly with the trailer and they explain it very well so it is an easy install. 480395

  • How to Access +12V Power Circuit in 7-Way Wiring to Power Fuel Pump
  • 7-way trailer wiring includes a +12V auxiliary power circuit that can be used for a range of purposes from powering an electric jack to topping off a trailer-mounted battery. This circuit is handled by the contact at the 1:00 position as you look at the vehicle's trailer socket. The ground is at the opposite pin, the one at the 7:00 position.

  • Replacement for Factory 7-Way Trailer Connector on 2001 GMC Sierra 2500HD
  • To replace the 7-way on your 2001 GMC Sierra 2500HD I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package # 74682 because it is an easy plug-in design. All you need to do is plug it into the 7-way socket on your truck and it will work as a replacement. For a trailer connector I recommend the Hopkins 7-Way RV Style Connector with Molded Cable # H20046 which is 8 feet long. If you want something shorter there is also the 6 foot # H20044 or 4 foot # H20043. I have added...

  • Wiring a Stop/Turn/Tail Light to Molded 7-Way Connector
  • The Stop/Turn/Tail Trailer Lights # ST21RS and # ST20RS will ground through the mounting hardware, so the two wires will need to connect to the Hopkins 7-Way Molded Trailer Wire Connector # H20044 simply by function. The red wire on the lights is for the tail light function, which is the green wire on the molded connector. The black wire on the lights is for the turn signal and brake functions, which are the red (driver's side) and brown (passenger's side) wires on the molded connector.

  • Recommended Parts for Re-Wiring 5-Pole Flat Boat Trailer to Match Truck 7-Way Wiring
  • Adapters like # 37385 and # HM47570 are convenient and can work fine for the short-term but for long-term reliability you are really better off replacing the connector on the trailer to a 7-way that matches your truck with no adapters - or their potential problems. Those extra connections can mean more chances for corrosion. You can easily test your truck's 7-way using a circuit tester like # 40376. Have a helper activate each function while you apply the tester to the appropriate pins...

  • What is Needed To Install Electric Brakes On A Master Tow Dolly That Doesnt Have Brakes
  • Before installing brakes on your trailer, you will need to know some basic information about your existing trailer. The first thing you will need to find out is if your tow dolly has a brake mounting flange mounted on your existing axle. The brake mounting flange provides a secure attachment point for a brake assembly. If you have a mounting flange, send me a picture or dimensions. See diagram to the right. This will help determine your existing brake mounting flange pattern. If you...

  • Available 7-Way Wiring Extensions for Camper Trailer
  • We have exactly what you need to provide a convenient 7-way socket for your camper. If your vehicle has a bumper-mounted 7-way socket that uses a round U.S. Car type connector that plugs into the back you can use the 90-degree 7-way harness # 41157 that you referenced. This is 10-feet long. Similar part # 50-97-410 is 9-feet. Such 90-degree harnesses are usually 8 to 10-feet long. We do offer a straight 5-foot 7-way extension, part # TLW6060, that plugs into your 7-way socket (not into...

  • Installing 7-Way Wiring Connector to Trailer For Reverse Light Function
  • The center pin on your 7-way on the trailer side is the reverse light function. These can be different colors, which I get is confusing, but you will need to do some deductive reasoning or use a circuit tester to determine the function and color. For instance the yellow wire on the Hopkins # H20044 or the Bargman # 50-67-008 is the reverse wire which isn't the norm because the yellow wire is typically the left turn and left brake wire. I've attached a photo and an article to assist. You...

  • Changing Trailer 4-Way Wiring to 7-Way Wiring for Extra Function and Compatible Connector to Truck
  • To switch your boat trailer from a 4-way to a 7-way connector, I recommend using the 7-Way Molded Trailer Wire Connector, 6' Long # H20044 along with heat shrink butt connectors # DW05744-5. You will ground the white wire to your trailer frame using # 44-5310A and then connect the running lights, right turn/stop, left turn/stop, and reverse light. To the reverse light (yellow wire on # H20044) you will connect # 16-1-1 wire sold by the foot to lead to your trailer reverse lights that...

  • Replacing Trailer Connector Wiring for Rockwood A122 A-Frame Trailer with 6-Pole Square Wiring
  • Instead of replacing both the 7-Way blade-style connector as well as the 6-Pole square connectors, # 37995, I recommend using a 7-Way connector and junction box to make the connections for your trailer. This will eliminate the additional, unnecessary connection at the 6-Pole square connectors. The 7-Way connector I recommend is the Hopkins 7-Way Molded Trailer Wire Connector with 6 Foot Lead # H20044. This connector will provide power for left turn and brake signals, right turn and...
