My wire harness was easy to install, looked great and performed great. One year later and it still looks and performs great! I definitely recommend to anyone building their own trailer or are looking to upgrade to better wiring! My homemade trailer was a great success, thanks to etrailer.com! 562417

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

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


Comments
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.

I installed this Hopkins connector cable on my 2003 Jayco 12 Sd popup camper because I replaced hydraulic brakes on it with the electric brakes. Needed some extra wires. Four were not enough to operate the lights and electric brakes. Installation was quick. I had to match wires on the trailer with cable wires. Cable looks great and so far it works great. We just checked out on our first camping trip this year. 528698

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


Comments
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.

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.

Excellent thick covering for the wires inside. Wires themselves are good quality too. The plug is durable and not cheap feeling. Overall the cable/wire system is very solid and I’m really pleased with the quality. I used this on my trailer project. (Bought this one, RV standard, and should have bought the other kind - not a big deal, just have to match colors up properly. I’m still very happy with it.) 814583

I recently ordered this power cord for my travel trailer as my original cord became corroded and difficult to engage into the tow vehicle plug. It is not hard to tell the replacement cord is far superior to the original, fit and finish is great and slides into the receptacle with ease. Installation was a no-brainer, took me about an hour. When I originally ordered the cord, I ordered a cord 1 foot shorter than the original. I gave etrailer (Rebecca) a quick call and she cancelled the original order and got me the cord I needed with no delay -- Thank you Rebecca. 806060

Everything arrived in perfect order and exactly as I was hoping for. I will get these parts installed on our horse trailer soon and will attach pictures once completed.

  • Adding 5-Way Harness to 2018 Toyota Highlander With 4-Flat
    I'm a bit confused by your question; the Highlander you are getting has just a 4-pin flat, is that correct? And you are looking to tow a trailer with a 5-flat?

  • Will 7-Way Connector Charge Auxiliary Trailer Battery
    The yellow wire on the Hopkins 7-Way RV Style Connector with Molded Cable # H20046 will not be able to charge an on-board battery, it should really be used for reverse lights. To charge the auxiliary battery on your trailer the best option is to use a battery charger such as the CTEK MULTI US 3300 12-Volt Universal Battery Charger # CTEK56353 which you would plug into a standard outlet. You can maintain that charge when driving by running # 10-1-1 wire along with 40 amp circuit breaker...

  • How To Wire In a 7-way to Replace a Boat Trailer 5-Way Flat
    You definitely could install the 7-Way Molded Trailer Wire Connector # H20046 in place of the 5-way that is installed on your trailer currently. The colors wouldn't match up exactly. White would go to white, you would run both brown wires to the single green wire of the 7-way. Yellow of your trailer would go to the red wire of the 7-way, and green of the trailer wiring would go to brown of the 7-way. Now without knowing where the red wires of the 5-way go it's hard to say for certain....

  • What Gauge Wire Should be Used to Wire Trailer Brakes
    That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary. On a smaller trailer with a single axle of brakes 12 gauge wire would probably be enough. But for a longer tandem axle trailer I would recommend you run 10 gauge wire to all the assemblies just to minimize the amount of resistance that would be on...

  • Can Electric Drum Brakes be Added to a Utility Trailer
    It can be possible to add electric drum brakes to an existing trailer that does not have them. The linked article explains in detail. The trailer will need to have or be fitted with brake flanges, the brake assemblies and hub/drums of matching dimensions and trailer wiring to support the brake circuit. The tow vehicle will have to be equipped with a trailer brake controller and a suitable trailer socket to match the one on the trailer. Typically trailers with brakes use a 7-way RV-style...

  • Does 7-Way Molded Trailer Wire Connector Have a Reverse Light Function
    Yes, the center pin on trailer side wiring harness # H20046 is for reverse lights on the trailer. For this particular harness it is the yellow wire. But it will only work if the center pin is functional on your 2012 Toyota Tacoma. If you have the factory installed 7-Way on the Tacoma then it should be active.

  • Where Does Yellow Wire of Trailer Wiring Connect to on 7-Way Wiring

    Yes, the terminals of the RoadMaster 6-Way connector and socket part # RM-910030-6 are compatible with 10 gauge wire like what comes with the # H20046. The center pin of the 6-way is the 12 volt accessory circuit and the ground is the circuit in the 2:00 position as you look into the opening of the connector.

    The Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard # H20046 will connect to your 6 wires function for function. Many trailers will not have the reverse light function, so it is likely that you have a ground yet it is simply a different color wire on your trailer.

  • How is Length of 7-Way Connector Lead Determined for Wiring Up Trailer
    The method you described would be a great way to determine what length to cut the # H20046. That way you would end up with enough wire that it wouldn't come unplugged when making a tight turn. Securing the wire up and out of the way is a smart option as well so that the weight of the cable would not want to pull it out of the connector and so that it doesn't get caught on anything.

  • Replacing Damaged 7-Way on Horse Trailer
    There's more than one accepted way to wire a 7-way, but the most common uses the green wire for right turn/brake, yellow wire for left turn/brake, brown for running lamps, blue for brake output black for 12-volt accessory power to the trailer, white for ground and purple for the reverse light circuit. Because wire colors can vary so greatly, we typically tell folks to wire by function, not by color. An alternative color code is yellow wire for auxiliary or reverse lights, green for running...

    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 # 329-HM318BKS. 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...
