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. .

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

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

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

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

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

This was purchased as a replacement for my utility trailer's connector. The wires inside are of a heavier gauge than the connector it is replacing. And the insulation seems more tightly molded around the inside wires. It seems like a quality item. 612191

Ask the Experts about this Hopkins Wiring
- How to Access +12V Power Circuit in 7-Way Wiring to Power Fuel Pump7-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. Please refer to the linked photo. For an easy way to access this power circuit to operate your fuel pump you could wire in a 7-way plug like #...

- Wiring a Stop/Turn/Tail Light to Molded 7-Way ConnectorThe 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.
view full answer... - What Does Yellow Wire of 7-Way Molded Trailer Wire Connector H20044 Wire ToThe yellow wire of the 7-way harness part # H20044 that you referenced goes to the center pin of the 7-way which is an aux circuit that is typically used for reverse lights if present on the trailer. Normally the red wire on a 7-way (RV standard colors) is for the left turn circuit so if you have a red wire I'd not think this would be the correct wire to connect the yellow if the 7-way to. Most likely you'd need to connect it to a yellow wire on your 7-way or to a purple wire. That...

- Would 7-Way Trailer Wire Connector # 7-Way Molded Trailer Wire Connector Work as 7-Way ReplacementIf your trailer has a 7-way installed on it already the part # H20044 would be a correct replacement for it. It would simply wire in place of your old one and work fine. For butt connectors you'd want the part # DW05745-10.

- Changing Trailer 4-Way Wiring to 7-Way Wiring for Extra Function and Compatible Connector to TruckTo 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...

If you prefer a longer connector, the same item is available in an 8 foot length as part # H20036 or an 11 foot length as part # HM20048.

- Installing 7-Way Wiring Connector to Trailer For Reverse Light FunctionThe 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...

- Wiring New Trailer Connector with Reverse Light Signal to 2015 Trailstar Tandem Axle TrailerThe easiest way to add a reverse light circuit to your TrailStar trailer is to tap into the reverse light circuit on your 5-pole, IF that is the assigned function. Often boat trailers with surge couplers have an electric reverse lockout feature that allows you to back up the trailer without having to first get out of the truck to manually engage a lockout (which prevents the brakes from actuating as you back up against the coupler). If your trailer coupler has an electric lockout feature...
view full answer... - Why is There 12 Volts on the Black Wire for my Trailer Connector If you are referring to the 12 volt pin that is located in the 1 o'clock position on the 7-way trailer connector then there should be 12 volt power feeding from the vehicle to the trailer on that pin. This means that if you test the 12 volt wire (usually black) before it enters and exits the controller, there should be 12 volts on either side assuming the 12 volt wire on the trailer is ran to a battery for maintenance changing purposes. Attaching two 12 volt power wires together will not...

view full answer... - How to Determine Wire Function for Replacing Trailer 5-Way with H20044 7-WayWhat you will need to do is verify the colors of the wire on your trailer. In some cases trailer manufacturers will use the standard wire colors to wire everything up, but there's no guarantee that's the case. Especially if someone else messed with the wiring at some point and didn't have all of the colors available. Trace each of the wires to be sure. It sounds like your white is ground, your wires bundled with brown are running lights but the rest can go a few ways that we have seen....

- Determining Wire Function On Boat Trailer With No Trailer ConnectorIt sounds like someone ran the wires as what we call a wishbone. The only way to tell how the wiring is connected to the lights is to use a 12V battery and a circuit tester like part # 40376. Attach the white ground wire to the battery negative terminal and then one by one connect the other wires to the positive terminal. You can have someone watch the trailer lights while you do the testing to determine what function each wire carries. Depending on how many lights you have on the trailer...

- Could Male 7-Way be Wired to Front of 2014 Honda CR-V for Charging Battery When Flat TowingWe have a 7-way with a 6 foot long harness part # H20044 that you could use to wire up like you mentioned. We don't have a more specific way to install a male 7-way on the front of a vehicle though so this would be your best option. The white and black wires of this have the heaviest gauge wire at 10 gauge so that would be the best to use for running to the battery.

You can use either the 7-Way Molded Trailer Wire Connector # H20044 or the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141, which is what I recommend using. Aside from just covering it up with something to help protect it, you will want to put some Dielectric Grease # 11755 on your trailer connector.

- Parts Needed to Make Custom-Length 7-Way Cable with ConnectorsTwist-lock connectors are fairly common within the RV power cord category, such as with RV Power Cord # 277-000145 which has a female twist-lock connector on one end, but not so much with vehicle-to-trailer 7-way connectors. If you need a very long 7-way, longer than the ready-made items like 6-foot # H20044 and 4-foot # H20043, you can use bulk 7-way cable part # DW04914-1 (sold by the foot) along with a male trailer plug # A7WCB to make one to your required length.

The problem is that the distance from the battery to the winch may not provide enough power to run your winch depending on how big it is and how much of a load you have on it. The best thing is to have an additional battery to run the winch only.

- Replacement 7-Way Trailer Connector with Wiring for a 2007 Sportsman TrailerFor you I recommend the Trailer Wiring 7-Way Upgrade Kit # ET7WK. This comes with an 8 foot 7-Way connector, wire loom, a junction box, and ring terminals. Everything you need to install a 7-Way. The junction box makes troubleshooting lighting and other problems much easier. If you already have a junction box then you can use # H20044 and just use ring terminals.

- Trailer Wiring Connectors that Carry Reverse Light CircuitThe most common trailer connector that carries the reverse light circuit is the 7-way. This is a very common connector style. Also the flat 5-way carries this signal as well. This is most common seen on boat trailers or others with surge brakes. For a 6 foot long harness with a 7-way we have the part # H20044. Or for a 5-way we have the part # HM47910. I also attached a help article on trailer wiring for you to check out too.

You do not need to add any fuses or relays. To make connection easy, I've attached an install video where they use a junction box like # 38656 but you can use butt connectors if you desire instead like # DW05744-5 and # DW05745-5. This same trailer connection function location will work with your Ram and buddy's Colorado as it use the same 7-way wiring locations.
view full answer... - Wiring to Use When installing a 7-Way Trailer ConnectorThe color of the wire you use doesn't matter but the wire gauge is important when installing a 7-way connector like # H20044. You don't want to use a gauge smaller than what is used on the connector. For example, the # H20044 uses 14 gauge wire for the red, brown, green, and yellow wires. But has 12 gauge for the blue brake wire and 10 gauge for the black 12 volt power and white ground wires. We carry 12 gauge # 12-1-1 and 10 gauge # 10-1-1. Both are sold by the foot.

Or if you are looking for something shorter you'd want the part # TLW6024 which is 24 inches long.
