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. .

Product is very well built; rock solid with nice durable wire. 127117
After a year, the product is still as good as it was the day I got it and it sits out year round.
Patrick - 04/24/2015The 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
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
Products were all as described and good quality. The only problem was packaging. The insulation on the wires on one of the brake assemblies was cut requiring splicing. Not a big deal but did require additional time and effort since they were cut where going through back plate. Wish I had purchased two conductor brake wire. Would have made job easier.But that was my mistake. 185439
No problems, everything working as it should.
Russell H - 04/15/2016The 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
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.
Mike M - 02/08/2018i 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
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
Exactly what I needed to get my heavy trailer back in shape! 645104
Product working great after 1 year! Thanks again! 644404
Haven’t made but one trip and seem to work ok. 643758
Everything from etrailer is always as described and great prices and quick shipping! 643454
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
Used this product to extend the trailer's factory cable due to the new tow vehicle's receptacle was farther from the camper tongue. After one year, it is still working well. All wire colors were correct. 620389
Very nice quality! Please with purchase. 616684
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
High quality, sturdy. Goes perfectly with the etrailer wiring box 596987
Exactly what I needed to rewire my vintage trailer. 579235
Has held up well, fits my factory plug perfectly on my 2010 Ram. It's nice to have a clean connector install on the trailer, looks professional, looks better than my beat up trailer lol 578568
Always a great deal and a very good pro duct. 570931
very good 556892
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
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.

Worked as it should. 548202
was a little short for what I was using it for 546847
Purchased Hopkins wiring to install in a customers car. The customer was and is very happy with the wiring. 544929
Well made product. No signs of UV degradation. Color coding didn't match my wiring configuration, but was easy to resolve. 543058
There are two generally accepted wiring color codes for trailer connectors, which is why we list the color code scheme that this harness uses on the product description page.
-- Mike L - 07/18/2018Excellent product. Quick shipping and easy installation. 542600
Great products, great service, easy ins tall! 524166
I had to reorder a longer one after finding that the 3 ft was too short for the location that I had to mount the junction box. Has worked well since instillation. 522205
Good quality plug and cord. 519453
I have not installed the new cord but it was exactly what I was looking for. 514819
This trailer harness is exactly what I needed. It is well made and I expect it to last for a lifetime. The wires are all correctly color coded and provide plenty of length. The instructions are provided and are easily understandable. I would recommend this to anyone needing a wiring harness. Etrailer is the best in customer service. 513943

Nice priduct 503111
Nice 498708
Functioned perfectly. Thank you 497403
A year later, and it still works great. Easy to use, does what it's supposed to. 495821
High quality products. Easy ordering and fast shipping. A pleasure. Thanks. 495711
Great web-site easy to navigate, great accurate descriptions. Good quick delivery. 489317
Shipping was very fast, and the products are excellent in quality! They offer a large variety for different parts and it’s what I use for my trailers! 488286
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
Cord quality id good but color code does not match plug in. That needs to be corrected it doesnt follow trailer light standard color code. 479413
The trailer connector you purchased does indeed use a different color code, which is why we specifically mention this on the product page. The connector would wire up as follows- White wire is Ground, Red wire is Left TurnBrake lamp, Brown wire is Right TurnBrake lamp, Green is Taillights, Blue is Trailer Brakes, Black is 12-Volt power from battery and Yellow is an auxiliary circuit, frequently used for the reverse lamps.
-- Mike L - 02/27/2018Great quality, timely transit and excellent customer service. 469128
