Video Transcript for This Old Trailer: Replace Wiring with a 7-Pole Cable

Today on This Old Trailer we are going to replace the wiring on this trailer. Right now, this trailer has a 5 pull socket here and the owner uses a patch cord in between here and his tow vehicle. What we are going to do is remove all this and add a 7-way cable that leads right to his tow vehicle. We will be using part number H20046. We will unbolt the connector here. Then we will go ahead and untape it and undo the screw right here, it should release the inside part where the pins are and the wires are connected. Tale that, push everything out. Simply disconnect our wires. 1:04

Now we have our bare wires, we will go over the code real fast. White is going to be your ground wire. Blue is going to go to the lock-out switch on the hydraulic brake controller. Yellow is going to be left turn. Green is going to be right turn. Brown is going to be your running lights. Now we are going to take our wire harness and thread it through the front here, try to guide it back to the hole where the socket was. We will take it and pull it on out, it is an 8 foot length, so we really do not need all of that. We will pull out some, and hook up our other end of the 7-pole to the tow vehicle and see how much slack we need. 1:53

We will use some tin snips to cut off our excess length. Cut the sheath so we can get to the wires. No we will strip back the wires on the ones we are going to use. We will use this green wire, red wire, yellow wire, brown wire, and white. We will not be using the black wire or blue wire since there are only 5 wires being used on the trailer. It is pretty tempting to match up the wires color for color, but you really can not do that because the 7-pole connector actually has a separate wiring code. In this case, green is going to be our running light circuit on the 7-pole, and on our trailer it is going to be brown. So we have to make the conversion. We will go ahead and start off by making our connections with that. To make our connections we will be using little connections called butt connectors. The wires butt together and we crimp them in place. Our next wire on the 7-pole is brown which is our right turn signal, and is going to hook up to green on our trailer, which is right turn. Red on our 7-pole connector is going to be our left turn signal, and the left turn on our trailer is going to be yellow. Next, we will work on our white wire that is the ground on the 7-pole, that will actually match up to our trailer so we will be doing white to white. Okay, our last wire is yellow on our 7-way connector which is the reverse lights and then on our boat trailer it is special so it is going to be the blue wire. 4:11

Now what we are going to do is tape this all together and seal it up for good. Tuck everything back in. We are going to wrap a zip tie around it which will help hold it in place. That will keep it extra secure. We will just leave this open, and now we are set. With that, that will finish our install of our 7-pole connector, part number H20046 on This Old Trailer.

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

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

This product installed easily and functions perfectly. My complaint is that the wiring colors used in the whip are not the standard trailer wiring colors. It would create a simpler installation if the color coding on the whip wires were standard trailer colors.8600

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

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

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

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 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

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

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

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

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

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

I like the sealed plug end and it's long enough that I can cut it to the lenght I need. Like other reviews have stated, the colors don't match up with your trailing. If you can use an ohm meter or test light to figure out which wires go were it shouldn't be a problem. 120211

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

Solid plug and the jacket is thicker than most other brands. Though the wire colors aren't the same as a 4-wire (Green=R Turn, Brown=Running, etc.), they did match the wire colors of the Pace trailer I was installing it on (Green=Running, Brown=R. Turn, etc.). 106230

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

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

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

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

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

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

Good wire. The moulded plug keeps the salt out. This was at least 50% cheaper than a tailer parts store. A trailer dealer said all of these wires have the colors screwed up. It sounds like the industry standard for colors is different with 7 way plugs than 4 way. 60174

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

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

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

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 Rick40639

  • 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 and stop,

  • Adding a Battery and Wiring to a Non-Powered Trailer to Add Interior Lights to an Enclosed Trailer
  • The first thing you will need is a battery and a battery box. The wiring for the light will need to be connected directly to this battery via a switch that you can get at a hardware store if the light does not already have a switch. Or you can install a new light that has a switch like the Trailer Dome Light with Switch and Aluminum Base, # IL61CB. Mount the switch in the trailer, route the wiring from the light to the switch, and then from the switch to the battery. If the light is just con

  • 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. He su

  • 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 corrosion

  • Equipping 2004 GMC Sierra to Maintain Battery on Enclosed Trailer
  • What you are wanting to do is actually pretty simple. The 12-Volt accessory circuit on your 7-way can be used to tend or maintain your battery on your trailer, but the circuit does not have sufficient amperage to charge a battery that has been completely discharged. Using a battery isolating solenoid like part # TR118665 would be advisable. This will prevent the battery on the tow vehicle from being discharged by disabling the 12-volt accessory circuit from the 7-way once the ignition on the

  • How to Wire a Hopkins 7-Way Trailer Connector # H20046 1987 Layton RV Trailer
  • There are standard colors for trailer wiring, but not everyone will follow those guidelines and since your trailer is older it is likely that the colors are different. The best way to wire up your trailer with this 7-Way Molded Trailer Wire Connector # H20046 would be to test all the functions of the wiring on your trailer and then wire the # H20046 to it by function. I attached a review video for this product and an FAQ on trailer wiring for you to check out. I also attached a picture

  • 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 be gro

  • What Parts are Needed to Install a 7-Way Trailer Connector on a 2002 Chevy Silverado
  • On the 2002 Chevy Silverado, there were a couple of factory wiring methods used. Some trucks will have a bundle of wires above the spare tire. The yellow wire is for left turn and brake lights, dark green is for right turn and brake lights, the brown wire is for running lights, and the white wire is ground. If you cut back the loom you may find 2 additional wires, light blue for a camper shell brake lights and light green for reverse lights. To wire in the 12 volt hot lead, you would need to

  • Mounting Two Trailer Stop, Turn and Marker Lights on Each Side of a Trailer
  • If you are using two stop/turn/marker lights on each side of the trailer, the only signal you will be able to separate out is the taillight signal. Trailers in the United States use a combined stop and turn signal so you would not be able to separate them to wire one light turn and marker and the other light brake and marker or brake turn and marker. You would essentially have two options. One light on each side stop/turn/tail and the other taillight only, or one light stop/turn only and the

  • 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 b

  • Can a Trailer Mounted Battery be Charged through a Trailer Connector
  • You can add a battery to the trailer that is dedicated to the lights in the trailer. However, you will not be able to up-charge the battery through the 7-Way connector, only maintain the current charge level. In order to charge up the battery you would need to use a battery charger like # CTEK56158. This charger works much better than the old trickle chargers that can overcharge a battery and not work to restore it. This charger provides 4 stages of charging that will help restore a batteries

  • 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. Each

  • Is a Battery Isolator Needed when Adding a Battery to a Trailer
  • First, the 12 volt circuit from a trailer connector, and most factory alternators on vehicles, are not able to charge up a trailer mounted battery. What they will do is provide a maintenance charge and keep the trailer battery at its current charge level. A battery isolator will only send power back when the vehicle is running. This will help to keep from draining the vehicle battery. Or you could just disconnect the trailer from the tow vehicle when you stop for long periods of time. If you

  • What is the outer Diameter of the Cable on 7-Way Molded Trailer Wire Connector, # H20046
  • I went out to the warehouse and grabbed a 7-Way Molded Trailer Wire Connector # H20046 to measure it for you. I used a set of digital calipers to get an accurate measurement. The diameter of the outer black sheath is 0.59 inches or 19/32 of an inch. A hole 5/8 of an inch would be perfect for this size cable. I have included a link to a video review of this connector for you.

  • 7-Way Trailer Connector for 2008 Toyota 4Runner
  • The part you refer to, part # H20046 is a trailer-side 7-way connector, and is not meant to be installed on a vehicle. If you wish to tow a trailer equipped with a 7-way connector, and your 4Runner was equipped with the OEM trailer towing package, it will already have the corresponding 7-way trailer connector at the rear bumper that will accept the H20046 plug you referenced. If the vehicle is not equipped with the tow package, you can install a 7-way. You would first need to install a traile

  • What is the Function of the Yellow/Brown Wire on a Trailer
  • Your yellow/brown wire most likely ties into the brown running light wire. Typically, when a trailer has a green/brown wire and a yellow/brown wire, they are both used for the running light circuit. The green/brown wire is ran down the right side of the trailer and the yellow/brown wire is ran down the left side of the trailer for the tail lights and marker lights. This prevents the need from running jumper wires across the trailer for the running lights. If your trailer is setup this way, you c

  • How to Install 7-way Trailer Connector on Trailer
  • If you are wanting to add brakes to your trailer, the correct way to to it would be to remove the 4-pole connector and install a 7-way harness/plug like part # H20046. You would use a junction box like part # 38656, and some 10 gauge wire like part # 10-1-1 to run the brake output circuit from the junction box to the brake assemblies. Each brake magnet will have two wires exiting it. One wire will ground to the trailer frame, the other will attach to the brake output circuit. The junction box pr

  • 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.
