Video Transcript for Hopkins Wiring H20046 Review

Today we're going to review part number H20046. This is the Hopkins Seven Way Molded Trailer Wire Connector. This trailer connector is an RV style seven way blade in with an eight foot long lead and the pigtail wires at the end.It is a pre-wired seven way trailer connector so this is all molded and pre-wired in the connector. The overall length of this including the connector is eight feet. Now the wire gauges on these-the blue right here is a 12 gauge. The white and the black are a bigger ten gauge and then the red, brown, green and yellow are all 14 gauge.Now one tip on this-what you want to do-there is a standard wiring color in the industry but not all manufacturers will go by that standard colors so what you do want to do-what you want to make sure is too when you install this to your trailer make sure to test the wires by function instead of matching color to color because the coloring in this will probably be different than is what on your trailer.What will also help you if you go to the product page for this part number there is a chart listed- a wiring code chart that'll show you what the functions are for each of these wires and what they compare to the standard trailer color wires.

That should do it for the review on part number H20046 the Hopkins Seven Way Molded Trailer Wire Connector.

The only reason I had to order myself a second one of these is that I cut the first one too short...after grumbling "measure twice, cut once" to myself about 50 times, I ordered the new one and will do the job right this time. I would also recommend using a junction box to make your connections; this helped me organize the project, and make neater, more secure electrical connections than simply splicing wires. Measure twice! // Kudos to Etrailer.com for getting this to me quickly. 126506


This molded plug pigtail has held up perfectly, in all kinds of weather, for the year that Ive had it installed on the trailer. Im still glad I wired it through a junction box like the one in Bob Hs review below. The box is a lot easier than managing 14 loose wires.

Hans V - 04/22/2015


Thanks for your follow up and reply. Also happy to hear that Bob H's review and suggestion of using a junction box was helpful to you.

Why not have the colors match? After running my wires neatly to a junction box then haveing lights not work right,I had to match each wire to the correct light,red to yellow,brown to green,green to brown.I come to warn other buyers and see they have the color codes on the site.So if all the trailers have the same colors, Why can't they just make the plug to match. 3503


I agree! All the right colors, all the wrong places: Makes no sense, and comes with no warnings. At least make all the wires one color, that way I would know its up to me to figure out! No warnings, no label.I am teaching students how to install wiring on a trailer, neatly, professionally, and using the DOT accepted national color codes. The end result was a mess of lights not working and backwards.Everything else ordered from etrailer was perfect. 4 brake and backing plates, seals, junction block, breakaway unit and 50 of cable. ALL standard color codes in everything. This Hopkins cord needs to have a very deliberate label on it, and it needs to say CAUTION: DO NOT FOLLOW STANDARD WIRING PRACTICES

Thank you for your comment. This is why we recommend wiring by function not by color. We do offer a chart above that shows the color of the wire, function of that wire, and the typical trailer wire that is should be connected to. I have also included a link to one of our helpful articles that show the different trailer wiring plug configurations for your reference.

Product shipped right away - ordered on Monday night and it shipped by lunchtime on Tuesday. (arrived Friday) I liked that I was notified via email with order confirmation and tracking information. The product was good quality and exactly as shown in the photo and description. I printed out the wiring diagram off the website, so the wiring presented no problem. An improvement would be to put a color diagram in the box with the unit. Other than that, everything was great. 92022


Still no issues - product is working great!

Great quality, fast shipping and the best customer service of any online retailer that I've dealt with. Although, I did not notice the "non standard" wiring (color coding). I struggled about a hour or so trying to figure out why my lights didn't work. Only after discovering that the wires didn't match the usual trailer wiring scheme I searched etrailer's site and found that it was described by others who had purchased these units. I think it would have been helpful to enclose the wiring scheme in the package to avert unnecessary downtime, even though it appears in the general description of the item on the website. Maybe alert with a large "IMPORTANT"?? Easily missed if you're already familiar with trailer wiring - you wouldn't be looking for it. Overall, I'm extremely satisfied with etrailer as I've purchased numerous items from them. Thank you Rick 40639


Thank you, I thought Id gone nuts! I hooked up everything perfect

Great item; works just as expected. No problems installing it at all, and combined with a 7 pin connector this fixed the issues I had been having with my running lights and trailer brakes. I couldn't be happier. 78107


This is still working great after one year. No problems at all...what can I say...its eight feet of good solid wire. I would buy this again.

This pigtail is an exact replacement for the one on my '04 Jayco. It was a quick job because I already relocated the junction box to inside the pin box a few years ago. What threw me for a loop was the wiring pin-out on the e-trailer site. I don't know if the standard is different on newer trailers but the lighting part of the pin-out (trailer side colors) is completely wrong (or different than my Jayco). As a sanity check I rang out the wires on the new pigtail with it connected to my truck and it turned out this was a color for color swap. It's good to make sure anyway. After the installation I used a jumper to power the circuits through the new pigtail just to make sure it was wired correctly. For the record I used: BLK = +12VDC WHT = Ground RED = Left T&B GRN = Tail BRN = Right T&B BLU = Brakes YEL = Backup Lights 209969

Pros: Best wire gauge in a 7 pin connector I could find. Cons: reverse lights (red), left turn (yellow), right turn (green), and running light (brown) and not wired correctly in the plug for their respective wire colors. I bought this for a sealed plug with good gauge wire to help save some time. What I got was a total headache trying to find out the problem of why it was not working correctly. This might not have been so bad had it not been on a new to me truck that I was not so trusting of the wiring in it. So I wound up looking at the truck first not thinking the plug would be wired incorrectly. Be warned. 13049

I ordered an exact replacement trailer plug from etrailer.com after my original was damaged. I was very excited to find that etrailer.com carried the original product. The quality of this product is the best on the market. The moulded plug and cable provide water proof and extra heavy-duty abrasion protection for my extreme duty dump trailer. I am very happy with this product. However, I am even more happy with etrailer.com. This is the first time I have ordered from etrailer.com. The service is great. My order was upgraded to a 3-day delivery, without extra charge. The product arrived a day earlier than even predicted with the upgrade. etrailer.com is on my favorites list from now on. 17352

Good product and quick delivery The connector is a high quality connector - well built and solid (and happily, it doesn't have the "etrailer" sticker on it like the picture - I was worried the sticker would get in the way of mating to the receiver). It's molded pretty solidly onto the wire 'bundle' and the insulation around the bundle looks built to last. The wires are high quality too. I was looking for a solid (as in quality) connector & wire harness to replace what I had currently on my trailer and this exceeded my expectation. And the shipping was quick too. (Another nice this about this site is all the documentation about wiring hook-ups etc...thanks!) 5382

After cutting my cable in half on my last outing with the Summerland travel trailer, I needed a replacement. I was worried about the reviews about color code being incorrect with this replacement 7-pin cable. Since I have a multimeter and understanding of basic wiring, I decided that the price was worth the gamble. Well, it definitely WAS. The cable is great, and the wire colors matched my previous cable exactly. Through research, I also found that THERE IS NO STANDARD code for trailer cable colors. Product is great, I am glad that this repair went smoothly and I can take the family camping again! 79047

My trailer cord was damaged during a recent trip and needed to be replaced. I looked around a several sites and chose 'etrailer.com' because of its reputation and reviews. Though some reviews stated that the wiring was mislabeled, I did not see that. We have a 2012 Keyston trailer and the wires matches one for one. Install was smooth, but I had the product wiring guide next to our trailer manual just in case. OTHER: Shipping was quick and product appears to be high quality (more so than the OEM that came with the trailer). Very satisifed customer and now ready for our next trip. 45731

This Hopkins 7-pin molded trailer wire is a very high quality cable. While I have not yet installed this product, a side-by-side comparison with the cable that it will replace suggests that this cable is fully-comparable, or even superior, in construction. Quality appears to be top-rank. I see nothing right now to suggest that I will not be fully satisfied. I also want to express my satisfaction with e-trailer as a business. This firm is a favorite of mine: extraordinary service, good prices, fast shipping, high levels of "in stock" availability--what a great operation. 41807

I purchased the 7-way trailer wire connector along with a junction box from etrailer for my stock trailer. First of all the shipping was fast and the communication from customer service was excellent. The items arrived exactly as pictured and described. etrailer sells at good prices and is on top of their game. The only reason I did not give an excellent rating is for the same reason stated previously about the manufacurer. Unless I am missing something it would make sense to manufacture the trailer connector using the same color convention as the wire harness. 7827

- H20046

by: Frank R.02/18/2013

Of course, this is an excellent product of high quality as expected from etrailer.. It is replacing the original on the trailer that had developed bad connections. I am a bit embarrassed to admit that I first used a shorter replacement that turned out to be too short to make hard right turns. So, advice from here is make sure you order one that is long enough. You can always cut it if too long. 66765


Its been on several long trips since then and still doing fine. I need to get back with you for a couple other items that I need want?

Molded plug is easier The junction box and molded trailer plug take a little extra energy to install- but the installation will be worth it, and replacements of the plug is much easier. The quality of the service from this company is Great! seldom do you find a combination of low prices, quality products and great customer service. My Order was delivered quickly and I received email advisory for each step of the process- including follow up on the delivery and they have installation videos and a great FAQ section. 4014

Awesome product, I really like how robust it is. I bought it knowing about the non-standard colors, but forgot about it when it arrived a week later. After wiring up the trailer and seeing things all messed up I remembered. Doh! Minus one star for the scrambled colors. But this baby is heavy duty and feels like it will last a long time. I did pair this with the 38656 junction box (http://www.etrailer.com/Accessories-and-Parts/Spectro/38656.html) so fixing the crossed wires was a snap. 88410

Had some real issues with this one. Should have noticed when purchasing this harness is not wired using standard truck/trailer color format. Other than that it went together fairly nice. If the connector would come apart I was thinking of fixing the wiring my self. 52399

Great Product I installed this trailer connector (along with the trailer wiring junction box, under the hood) on the front of my pickup truck so that I could connect it to my motorhome for flat towing. It appears to be a high quality, well made product. The outer jacket of the cord is very soft and supple and easy to work with. Shipping was VERY quick. I didn't expect to see the product until Thursday, but found it on my porch on Tuesday afternoon. 5017

- H20046

by: Bill D.08/20/2012

The wire connector is a great product. Including instructions with it would be helpful. The only issue is the difference in colors from the trailer wires to the wires in the connector. It is physically impossible to connect them one at a time because you must disconnect the old connector from the trailer to have room to put in the new one. Taking pictures is of no use because of the way the wires are all mashed together within the electrical box. 52351

Item arrived on schedule, and was as advertised. Installation posed no particularly difficult problems, and all the lights and brakes worked properly when hooked up to my truck. I wish I would have ordered the Etrailer terminal box when I ordered the cable, but i installed the cable using the RV's original box and spliced into the trailer wiring with ring lugs and screws and nuts, taped thoroughly afterward. 185460

by: Paul F.02/28/2014

Nice! Sealed unit not open to collecting water like the splice in connectors you buy at the autoparts stores. Can't beat the price locally. Seems like a quality piece. Plug is solid plastic. While its still plastic it is 10x better than the hollow cheap ones i'm used to. Already wired in the plug side and permanently sealed, one less set of connections you need to worry about. 117977

Not rocket science 7 wire cable with a plug stuck to one end, not rocket science, product looks fine out of the box and I expect it will carry electrons where I want them. The item got here in good shape and quickly. No instructions included but if you can't find those on line you shouldn't be doing this stuff yourself, get a professional to do it for you. 4398

Cable length is approximately 8', a bit on the shorter side though. The issue I have is that the color code doesn't match up with the standard trailer color code. Fortunately I was using a junction box so straightening it out was simpler than if I had used crimp connectors. Otherwise it appears to be good cable & connector. Time will tell on durability. 63587

This wire harness is better than the factory harnesses I have replaced on all the trailers I and my son's own (9). I like the heavy cord design for durability. The 8' length is just right for gooseneck and 5th wheel applications. This time I upgraded my gooseneck horse trailer. The cross reference chart posted in the information section was handy. 55187

Productio is extremely well made. Purchased to hook my boat trailer to a new GMC truck.

Ordered late in the day and yet it was shipped that same day. Great work. Thanks 30033

Very happy with the quality of the cable and the connector. I was not too worried about the color-to-color matching of the wires; a little extra effort and a sensor light takes care of that. A minor inconvenience, and you should have a tester light on hand anyhow. Its the quality, pricing and quick delivery that gets the high rating. 27489

From the extreme tips of each end this product was just *less* than 8' long. If you need *at least* 8' then buy the 10' version. Other than the length issue, the product is well made and wire colors are industry-standard. If using crimp-on connectors, know in advance that two wires are 10-gauge, one is 12-gauge, and four are 16-gauge. 148635

Extremely fast shipping!! The only complaint that I have is with the product itself. The connector is manufactured by Hopkins, and the wires do not match up with their online wiring diagram. You are shorted one 12 gauge wire, and have to figure out a couple of other wires functions. This in no way reflects on etrailer. 8025

This long connector is exactly what I need for my camper. I added a longer receiver as the clearance between the tailgate and electric tongue jack was VERY tight (1/8") and at times would hit. As a result the cord became very tight and would actually come out when in some turns. The extra length was perfect! 64039

I liked a molded plug on the end of my cable. It keeps the Minnesota road salt and grime from getting in from the back. Some guys like the type of end that comes apart so they can replace it. If it comes to that, just cut the end of the cable plug off and put a different end on. This is a good heavy cable. 9758

Wiring was incorrect. Had to rewire in accordance with function of vehicle, not wiring diagram. Otherwise OK. Had local mech install the ETBC7 kit and the Prodigy 2 (90885). He did a good job, but took about three hours. Installed in a 2013 Subaru Outback. Seems to work OK at this time. 150583

Agree with previous reviewers as to the wire color not matching the standard scheme for 4 of the wires. Standard/Should be color >>> Actual harness color. Purple >>> Yellow. Brown >>> Green, Yellow >>> Red, Green >>> Brown. Color aside, appears to be a quality molded plug and harness. 90347

  • Re-Wiring Old 4-Wire Boat Trailer Plug With a New 7-Way Trailer Plug
  • Considering that the 4-wire round connector on your Dad's old boat trailer may be nearing the end of its life (due to use and corrosion) you will be better off replacing the 4-way round connector with a 7-way plug such as # H20046 from Hopkins. Installing a new trailer-side male plug will also avoid the complication and cost of having to use an adapter and it will make the trailer much more user-friendly to the majority of tow vehicles likely to pull it in the future. Installing the...

  • Color Clarification Regarding Wiring Issues of a 7 pin Trailer Blade Connector
  • Figuring out what color wire goes to what function is sometimes quite confusing. I have attached a diagram which covers both the most common wire colors designated for a seven pin trailer connector and a seven pin vehicle connector, referencing the wiring colors for each blade and what each blade is responsible for. If you look up part # H20046, you will see about 1/3 of the way down the page a chart that will give you a wiring guide. It gives you the color of the wire and how it relates...

  • Adding a Battery to a Snowmobile Trailer for Interior Trailer Lights
  • Start with mounting a battery. Since the trailer is enclosed, it would be a good idea to mount it on the trailer frame using a battery box like # DW03189. Next, you will need to have the right kind of connectors on the truck and trailer. I would use a 7-Way RV style if you do not already have them on the truck and trailer. There is a 12 volt circuit on a 7-Way. You can run a wire from the 12 volt circuit on the trailer side connector to the positive battery terminal. The battery should...

  • How to Wire 7-Way Trailer Connector on Old Golden Falcon Travel Trailer
  • There are a two schools of thought regarding trailer wiring color coding, which is why we recommend wiring by function, not color. The company that supplies us with molded trailer connectors like part # H20046 use the following color code: Red = Left Turn/ Brake Brown = Right Turn/ Brake Green = Running/ Marker Lights Blue = Brake Output Voltage Black = 12-V for Trailer Accessories Yellow = Auxiliary The following color code is also very common: Green = Right Turn/ Brake Yellow...

  • Tekonsha Primus IQ Trailer Brake Controller # TK90160 Shows No Connection to Trailer
  • Your Tekonsha Primus IQ # TK90160 brake controller will display the NC message (indicating the trailer is not connected) for any of several possible reasons: if the trailer is not connected, if the connector has corrosion, if there is an open circuit on the brake line, if the trailer brake magnet loses its ground connection to the trailer frame or if the brake magnet is malfunctioning. Although trailer lighting functions are carried on the same 7-way connectors, since they are on separate...

  • Trailer Hitch, Weight Distribution, Brake Controller, Wiring, Accessories for a 2009 Toyota Sienna
  • First, we should start with a trailer hitch for the 2009 Toyota Sienna. The most popular hitch for your vehicle is the Hidden Hitch Trailer Hitch, # 87415. This is a Class III trailer hitch rated for 350 pounds tongue weight and 3,500 pounds gross trailer weight. When used with weight distribution it is rated for 500/5,000 pounds. I have included a link to the installation details and a video showign a typical installation. Next, you will need a ball mount, ball, and hitch pin. I recommend...

  • Gooseneck Trailer Lights Get Brighter on One Side and Marker Lights Come on with Brake Lights
  • Checking the grounds was a good place to start. I think that it still may be a ground issue. There are several things you can check to determine if it is a ground problem. I would start with the trailer side connector and check for any dirt or corrosion and clean it out. Dirt and corrosion could cause a bad connection or a short which would lead to undesired results. Next, I would check the ground coming out of the back of the trailer connector. It should be connected to a clean and...

  • How Much of Each Gauge of Wire Fit Inside a Wire Loom Comfortably
  • I would certainly recommend the 1/2-inch wire loom # 459075-1. It will hold two jacketed 2 wire 10-gauge wire and three jacketed 2 wire 12-gauge wire. See pictures to the right. In addition, I was able to fit comfortably eleven individual 16-gauge wire # DW02359-1 into the 1/2-inch wire loom. I also took a digital caliper to measure the exact radius of each type of wire: 10-gauge is .17 of an inch, 12-gauge is .14 of an inch and 16-gauge is .09 of an inch. The 10, 12 and 16-gauge...

  • Building Tiny House on Flatbed Trailer and Need Brake Controller and Wiring for Electric Brakes
  • Thank you again for ordering with etrailer.com, we appreciate your business. From the measurements that you have given me, I recommend getting about 35 to 40 feet of 10 Gauge Primary Wire, # 10-1-1, in order to wire the electric brakes on your trailer. Depending on the tilt function of your trailer, you may want to order a bit more to be on the safe side. I have attached a wiring diagram that illustrates the basics of wiring your trailer. A couple additional items that may want to...

  • Wiring a Camper 7-way Connector Using the Pollak Metal 7-Pole RV-Style Socket # PK12703
  • The part that you referenced above, the Pollak metal 7-pole Trailer connector # PK12703 mounts to the towing vehicle. This 7-pole, also known as a 7-way connector, supplies the trailer with signals for the following: trailer brakes, trailer reverse lights, an accessory 12V battery power, right and left turn signals, running lights, as well as ground. Yes, the black wire is a 12V power supply on the 7-way vehicle connector and it will connect the vehicle battery to the 7-way vehicle...

  • Converting Existing Hydraulic Brake System to Electric on Pop-Up Camper
  • The Dexter Hub/ Drum you mentioned, part # 8-173-16UC3 would be a proper replacement for you as long as the inner and outer bearings in your existing hubs are # L44649, the grease seal is # 10-9 and the 4-on-4 bolt pattern matches up with your existing hubs. Your existing bearings and grease seals should have reference numbers stamped on them, make sure the numbers on the existing parts match those of the replacements. You will also need electric brake assemblies, part # 23-47 for the...

  • How to Wire a Trailer with Electric Brakes to a 1995 Ford F-150
  • We can certainly help you get set up with what you need to tow your trailer. Starting with the brakes on the trailer, (which I am going to assume are operational) each brake magnet will have two leads coming out of it. One lead needs to be grounded to the trailer, the other needs to be connected to a 10 ga. wire that runs to the tongue of the trailer. Run one lead from the brakes on the other side to this wire as well. On the trailer side, you will need a 7 way connector plug, part # H20046,(there...

  • How To Hardwire a New 7-Way Trailer Connector by Function When Wire Colors Do Not Match
  • You will need to wire the 7-Way Molded Trailer Wire Connector, # H20046, for function rather than by color. Since the trailer side needs to be replaced, you will need to trace the wires back to see which wire does which function. An easier option would be to test the connector you have, before replacing it, to see which wire color matches which function on the trailer side of the connector. Using a circuit tester, like the Quickee # 3808, test the trailer side wires for: right turn...

  • Diagnosing Malfunctioning Turn Signal and Brake Lights on Gooseneck Trailer
  • Although the brake and turn signals work on the truck, I would recommend testing the 7-way connector on the truck to determine if the problem exists in the trailer wiring on the vehicle, or on the trailer. Use a circuit tester like part # 40376 and test the pins on your 7-way that are in the 3:00 and 9:00 position. With the right turn signal on you should see power on the pin on the 3:00 location. With the left turn signal activated, the pin in the 9:00 location should light up the tester....

  • Brake Controller Install on 2012 Subaru Outback
  • The Tekonsha Primus you mentioned should work very well for you and would be a good choice unless you are planning on towing a trailer with an electric over hydraulic braking system some time in the future. If this is the case, you might want to go with the Tekonsha Prodigy P2, part # 90885. Since you need to provide a connector for the trailer anyway, I would upgrade to the more common 7-way connector. This way you could tow the trailer with a different vehicle if need be. To install...

  • Truck/Trailer Brake Lights Come on with Trailer Connected and not Using Brakes, 2001 Toyota Tundra
  • From what I have been able to gather, the 2001 Toyota Tundra did not come with a tow package that included trailer wiring connections. This could mean that it was done aftermarket and could have been wired incorrectly by a previous owner. Or there could be a bad ground issue causing the malfunction. I recommend checking the ground connections on the truck and trailer side connectors. They will need to be clean and free of corrosion. I spoke with one of our installers about this problem....

  • Using a 2-Wire Trailer Tail Light on a Trailer with Separate Brake and Turn Signals
  • Since you have indicated that you do have separate turn signal and brake light wires on your Scamp trailer, connecting both of those separate wires to the same circuit on the light # STL90RB is probably what is causing all of the problems including back feeding to the truck. What you will need to do is use a special converter on the trailer side, # RM-732. The separate brake and turn signals will go to the input side of this converter which will then combine them for the output side....

  • How to Power Interior Trailer Lights on a Trailer Not Powered by a Tow Vehicle
  • First, you need to make sure that the lights you will be using are compatible with a 12 volt system because that is what a battery will produce. Since the trailer will not be connected to a tow vehicle for power, you can wire in the lights independently from a trailer connector. What you will need to do is mount the lights and route the wiring to a switch, like # BL0108-00. You will need to make sure to ground the lights to the trailer frame. Then you will run a power wire from the positive...

  • Truck Bed Wiring for a Slide in Camper on a 2008 Nissan Titan
  • With a camper in the bed, and an in-line wiring harness connected, you will retain the use of the 7-Way at the rear of the truck (if it has a factory tow package) but you will not be able to use both at the same time. Either the camper can be plugged in or the trailer. Trying to use both at the same time will overload the electrical system in the truck. If your 2008 Nissan Titan has a factory tow package, what you can do to provide wiring for the truck bed camper is install the Draw-Tite...
