Video Transcript for Hopkins 4-Pole to 5-Pole Trailer Wiring Adapter Installation

Today we are going to show you how to install the 4-wire flat to 5-wire flat adapter, part number 47515 from Hopkins Towing Solutions. This adapter piece allows us to plug in to the vehicles existing 4-pole plug and adapt to a 5-pole plug that you find commonly on boat trailers with hydraulic brakes that offer a reverse lockout. The adapter piece itself is very simple to install. Again, you have the one side that is going to plug into the vehicles existing 4-pole and the other end will come out with the new 5-pole plug that you will need for your trailer. What we do need to do for this adapter, however, the fifth wire is the reverse lead. So we will need to find the reverse wire on the tow vehicle and manually tap this in. So we are going to start by just plugging the 4-pole in, into the vehicle harness. And then we need to figure out a way to get up to the reverse wire on the vehicle. 0:53

Another nice feature of this adapter is that right in the middle of our reverse wire is a disconnect point. So what we can do is I can actually go ahead and disconnect that wire that is in behind the taillight and it through. But once it is installed, it will allow you to leave this end connected to the vehicle at all times. And if you want to remove the adapter from the vehicle you can just disconnect it at the quick disconnect point. Now the easiest place to wire in the reverse lead is actually behind the taillight itself. We want to go ahead and figure out how we can get behind the taillight assembly. Now on this particular vehicle, if we follow over to the driver side, underneath where the taillight is mounted, there is a hole there that we can easily route the wire up and get behind the taillight. So we are next going to go ahead and take off the driver side taillight and figure out which wire is the reverse wire. Ok, so I am up to the driver side taillight now and we need to figure out obviously how to remove it so we can get to the wires. On this particular vehicle, the mounting screws are on the inboard side. There are two of them here. Take those out so we can get to the wires. 2:09

Ok, with the taillight pulled off, we can see the wires here. And again we are looking for the wire that is activating our reverse lead. The reverse light on the vehicle is always behind the clear lens. So if we go behind the taillight, the two wires going into the clear lens. This one is the ground and this one is going to be our reverse light. And again, on this vehicle it is a red wire with blue stripe. So I am going to cut back a little bit of the tape to hook in my quick splice. From there we will take the provided quick splice, mount it over top of the red wire here and then we will take our other half of our reverse lead wire from our adapter and go ahead and slide it into the other groove on the quick splice. Just take a pair of plyers and we are going to crimp down on the metal tab on the top. And out connection is made. From there we want to go ahead and take the other end of the wire and just feed it down through the opening that we had found earlier. And you want to just feed the full lead down. And then we can go ahead and put our taillight back on. And then back underneath the vehicle, we just need to route the reverse lead wire back over to our adapter. Plug the two pieces together and our installation is complete on it. From there you just want to take your blue wire and go ahead and secure it up out of the way, with some zip-ties if need be. Now I do want to note that this is essentially an adapter piece but it actually does not need to be ever removed from the 4-pole because a trailer 4-pole will actually plug into this new adapter piece just fine, just like it did on a common 4-pole. And that will conclude the installation of the Hopkins 4 to 5-pole adapter, part number 47515.

Put this on an '05 Ford F150. Simple install and took only 5 minutes. Drivers side reverse tail light has two screws on the tailgte side. The hot wire for backup light was brown w/ a red stripe. Unfotunately, my package didn't have the wire splice connector inside as it was suppose to so I used stuff I had at home. Works like a charm. Very clean looking with no extra wires dangling. Should get 5 stars but the lack of connector bummed me out and I didn't have time to return it. Cheers 44918

This product is very well made. Instructions are a bit brief, but plenty of info online to get it installed. The reverse wire on my car was too small to work with the splice, but I connected them directly w/ a "T". Worked flawlessly with my trailer. The length of the wire on the adapter allows you to make the connection INSIDE the car which will surely extend the life of the connection. Overall great and simple design. 153312

Great Product! It was a very easy install. The blue wire is only long enough to go to a reverse light that is on the rear corner. I had to buy additional wire from the auto parts store to continue the connection up the side of my vehicle and through the back hatch. But it works great. 1639

This is an excellent adapter; however, I didn't give it the highest rating possible because the wire is not as long as I needed. While it was easy for me to add a section of wire, I don't understand why it's not about a foot longer so that it would work easier on any vehicle. 118185

  • Yes, there is a way to back up your boat trailer and keep the surge brake actuator, # T4332900, from applying pressure to the trailer brakes. You will need an electric lockout solenoid, # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed. Along with the solenoid, you will need a solenoid cover, # T4835800183, if your actuator is the model 60 actuator that you referenced. The cover will keep the solenoid from getting stepped on and damaged...

  • Wiring Trailer Lights for 2009 Pontiac Vibe Without Using Converter
  • Probably the easiest way to handle this situation would be to use a 5-way connector, part # 20017 for the trailer and part # 20016 for the vehicle end. Use the extra wire for the brake light lead. If the trailer needs to be towed by another vehicle, simply use the 4 to 5 Way Adapter, part # 47515.

  • Troubleshooting Trailer Lights Working Erratically on a Trailer Towed by a 2000 Jeep Grand Cherokee
  • There are several things you can check. First, check the functions on the vehicle side with no trailer connected. Make sure the wires are receiving the proper signals at the connector on the Jeep. You will need a circuit tester like the Quickee # 3808. If you find a problem at this point, something may not be wired correctly and you will need to start from scratch. Wire color and functions are usually: white = ground, green = right turn and brake, yellow = left turn and brake, brown = running...

  • Adding Trailer Wiring to a Motorcycle to Tow a Trailer
  • Motorcycles have separate brake lights and turn signals. Most trailers, unless designed for use with a motorcycle, have combined turn signals and brake lights. You will need to convert the separate signals on the bike to match what the trailer requires. To do this you will need a converter like # 119178. On this harness you will connect the white to ground, green to the left turn signal, yellow to the right turn signal, and red to the brake lights. Brown is the running lights. If it...

  • Adapting 2010 Ford E-350 With 4-Pole Wiring Harness to Tow Boat Trailer With 5-Pole Flat Connector
  • There are several ways to adapt your different tow vehicle and trailer connectors. The most cost-effective method to put a 5-pole flat connector on your vehicle is to use Hopkins 4 Pole to 5 Pole Trailer Wiring Adapter, part # 47515. Installation is simple and consists of connecting your existing 4-pole and making one single splice connection to the reverse light circuit at the back of the van.

  • Trailer Wiring Recommendation for a 2008 H3 Towing a Boat Trailer with a 5-Way
  • I can help, you will need to order a Draw-Tite Wiring Harness # 81252. This is a hardwire kit that will require you to use the included circuit tester to determine the functions of your tail light wiring harness and wire them to the # 18252 accordingly. I attached installation instructions and an install video for this product for you to check out as well. Once that is installed you will have a 4-way. Now you will need to convert this to a 5-way, in order to do that you will need a Adapter...

  • Comparing 4-Way to 5-Way Trailer Connector Adapters # 20036 and # 47515
  • 4-Way to 5-Way adapters # 47515 and # 20036 are essentially the same. The difference is that # 20036 has longer wiring with it than # 47515. For that reason we normally recommend # 20036. The 4-Way to 5-Way portion is 18 inches long. The blue wire though is 60 inches long from end to end. Additional light gauge wire, such as # 16-1-1, sold in 1 foot increments could be spliced in if a longer connection is needed.

  • Can a USA 4-Way Trailer Connector be Used with an Australian Trailer Configuration
  • The Australian 7-pole is like the European 7-pole in that it has separate turn signals and brake lights (and a few other functions not used in the states). A US 4-Way and trailer will have the turn signals combined with the brake lights on each side of the trailer. So you would have a ground (earth), running lights, left turn and brake lights, right turn and brake lights. In order to separate out the turn signals from the brake lights you would need a converter, # 118158. You would wire...
