Video Transcript for Hopkins Wiring 47515 Review

Today, we'll be reviewing part number 47515. This is the Hopkins Adapter 4-Pole to 5-Pole Trailer Wiring Adapter. The trailer wiring adapter is going to change the 4-pole flat on your vehicle into a 5-pole flat. You can see here that you have the 4-pole connections you plug into the 4-way flat on your vehicle. On this side, it's going to convert it over to a 5-way connection. Now, the blue wire is the wire that's going to get spliced into the reverse light wire on the vehicle, which is easily done with the included quick splice wire connectors. That is included with this part number.

This is going to be great for use with marine trailers equipped with surge breaks to eliminate rewiring your vehicle or trailer. When installing this, you want to make sure to use a tester to locate the backup wire at the rear of your tow vehicle. You're then going to splice the blue wire onto the backup wire of the tow vehicle using the supplied splice connector. Once you have that done and secure, then you can simply just plug in the vehicle end and the trailer end and then you would be all set to go. The blue wire, you can see here that it has a little inaudible 00:01:06 connector on it that connects the two pieces together. When fully connected, that's going to give us a total length of around 56 inches. That's going to do it for today's review of part number 47515. This is the Hopkins Adapter 4-Pole to 5-Pole Trailer Wiring Adapter.

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

Still works but seems sporadic at times. Will investigate my hydraulic servo for the brakes to ensure they are locking out as required to reverse.

Jeep Wrangler Unltd


Great product! I have a Jeep Wrangler Unlimited that only has a four pole flat connector. I have a boat thats needs a five pole because it has surge brakes. This was the perfect solution. I just had the fifth wire connected to the back up light and plugged this five to four pole adapter that was already on the vehicle. Problem solved. It came quickly. I accidently ordered two and I got a call from Etrailer questioning my order. I thanked them and said I only needed one. They saved me the cost of the second adapter when most companys would have just sent them both- and charged me for two. 154766

2016 Kia Sorento


I put this on my 2016 Kia Sorento. Do yourself a favor and watch this instructional video "Hopkins Trailer Wiring Adapter Installation - 2014 GMC Acadia". Another great tip for my application is to buy an extra 20 feet of 16 guage wire. I ran the wire from the tailgate on the inside of the weather stripping and snaked the wire into the utility tray in under the back flip up compartment. When I need to hook up the adapter - I just run it out of the tailgate and hook it up. This keeps the adapter out of the elements when not in use. 191722

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

2014 Ford Escape


This product was everything that is says that it is. Suggestion for hatchback owners, though. See if your reverse lights are in the hatchback or on the fender panels before purchasing this product. If they are in the hatchback, as in the 2014 Escape, then you will need to purchase a longer adapter or additional wiring as the routing of the wires to the closest reverse wire is substantial. 153594

Excellent product. Connected it in about 10 minutes. Had to remove the taillight and splice to back-up light (splicer included). Easy install (pug and play) and works great. Thanks for having this online at your store. Could not find one locally in Houston area (can you imagine). Excellent pricing and free shipping! Doesn't get any better. 142512

Terrific online company! Their website is easy to use and contained tons of information, including multi-angle pics and videos, so I was sure I was getting the exact part I needed. It shipped very quickly and I had the wiring installed and complete in just a few days after I placed my order. I highly recommend etrailer.com! Thank you!!! 202471

I Have been looking for this product for a long time. I did not know the part number or even that it existed, I just had a need. At etrailer.com I not only forund this product. I found a couple versions of the same solution. Plus etrailer showed me a video on how to install it. Great site 16301

by: Chris03/11/2009


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

by: Mike E.03/02/2014


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



- 47515

by: Dave S10/19/2014


Product is exactly what I want, but should include a dust cover. Also, wire that leads from plug is too long, and the tail light wire is too short. Where they connect should be closer to the plug, because the way it is you can't really unplug it from underneath the vehicle. 156751

  • Trailer Wiring for a Motorcycle Towing a Motorcycle Trailer
  • Normally, the 5 wire flat connector will accept a 4 wire flat connector and work properly. The extra circuit on the 5 wire connector is normally wired to power a reverse lockout or electric trailer brakes not the brake lights. If your motorcycle has the brake light circuit connected to the extra circuit you will need to do some re wiring or install a converter, item # 119178KIT, on the motorcycle. Your trailer should be wired as follows. White wire = ground, brown = tail light, yellow...

Use a circuit tester such as # 3808 if you do not already have one to test and find the correct wire. It looks like the reverse light wiring will go through the rear hatch.

  • 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 the 5th Wire of the Adapter 4 Pole to 5 Pole Trailer Wiring Adapter Be Cut Off if Not Needed
  • Usually, on a boat trailer with a 5-Way trailer connector, the 5th wire goes to an electric reverse lock out on a surge coupler. This is so when you put the vehicle in reverse to back up, it will not allow the trailer brakes to engage so the trailer can move. If you do not need the blue wire on the Adapter 4 Pole to 5 Pole Trailer Wiring Adapter, # 47515, you can just tape it up and and stow it out of the way. I would not cut it off because you may need it in the future. If you do...

  • Can a 4-Way Flat on a Truck Be Used with a Trailer 5-Way Flat without Connecting Extra Wires
  • I recommend using the Adapter # 47515 or # 20036 and not connecting the extra blue wire to anything on the truck. On a 5-Way flat connector, the extra blue wire is normally for an electric reverse lockout which you find on a lot of boat trailers. The brakes on the trailer are probably hydraulic with a reverse lockout on the coupler. The blue wire sends power from a reverse light circuit to a solenoid on the coupler that does not allow fluid to pass through to the brakes when the vehicle...

  • 5 Pole Trailer Wiring Harness for towing Boat Trailer with 2013 Toyota Sienna
  • To install a 5-pole flat trailer connector on your Sienna, you have two alternatives. You can use the modulite kit, part # 118498 that would plug inline with the connection between the vehicle wiring harnesses and the rear of the taillight assemblies and a power wire would be ran to the vehicle battery. You'd then use an adapter like part # 47515, with the extra wire on the vehicle side getting tapped into the circuit that feeds the reverse lamps. Your other option would be a hardwired...

  • How to Make a Charge Wire for Flat Towing Vehicle with Tow Vehicle with 4-Way
  • To trickle charge the battery on your vehicle you will need to use a # 37185 to convert the 4-way on your tow vehicle to a 7-way. You will need to route the purple wire of this 7-way to the positive side of your battery on your tow vehicle through a circuit breaker like part # 9510 and 10 gauge wire like part # 10-1-1. Now for an umbilical to go from the 7-way to a 5-way you will want to use the part # HM47075. You will then need to use the part # 47515 to convert the 4-way on your toad...

  • How to Find the Reverse Light Wire on a 2004 Lexus RX330
  • First, located the tail light wiring behind one of the tail lights on the 2004 Lexus RX330. Then, use a circuit tester, like # 3808, to probe each of the wires until you find the one that carries a signal when the vehicle is placed in reverse. You will need to have someone sit in the vehicle cab and put it in reverse. It is a good idea to apply the emergency brake, regular brakes, and even chock the wheels to prevent the vehicle from moving while in reverse. Once you have found the...

  • Recommended Trailer Wiring Harness for 2016 Toyota Highlander Towing Boat Trailer w/ Surge Coupler
  • There are two different options available. You can use a plug and play wiring harness like the Tow Ready # 118449 along with an adapter like part # 47515. The 'extra' blue wire from the adapter would tap into the circuit feeding the reverse lights on the rear of the vehicle. This would be the easier installation, but it involves using an adapter. The other alternative would be a powered converter, part # 119177KIT. You'd access the taillight wiring harnesses behind the taillight assemblies...

  • Recommended Converter To Convert Combined Wiring On Vehicle For Trailer With Separate Wiring
  • We do have a converter that will let you convert the combined brake and turn signals from your Honda without splicing into the vehicle wiring. The wiring would be done on your trailer. I recommend part # 118158. You would cut the harness on your trailer and wire it to the 118158 converter as shown in the attached photo. Since it is not waterproof, you will need to use a junction box on the trailer like part # 38656. You would need to use a 4-way trailer-side connector like part...

  • Locating the Reverse Light Wire on a 2008 Honda Odyssey to Install a 4- to 5-Way Adapter
  • To find the correct wire on your 2008 Honda Odyssey to connect to the blue wire on the 4- to 5-Way adapter # 47515 you will need to test the vehicle wiring using a circuit tester such as # 3808. It looks like the reverse lights are on the rear hatch of the 2008 Odyssey. There should be a wiring harness that goes from the hatch to the vehicle interior likely up near the roof. There is probably a protective sleeve covering the wires that you will have to move or cut open to access the...

  • Can a 4-Way to 5-Way Trailer Connector Adapter be Safely Used on a 2013 Ford Edge
  • The 4-Way to 5-Way adapter, # 47515, will work well on a 2013 Ford Edge and will not short out the vehicle electrical system if installed correctly. Installation is straight forward. The 4-Way on the vehicle plugs into the adapter. The blue wire then will connect to a reverse light wire on the vehicle using the included quick splice connector. This adapter is not circuit protected so if there are shorts on the trailer they could back feed to the vehicle. Make sure the trailer wiring...

  • 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...

  • Using a # A75TB 7-way to 5-pole Adapter to Tow Boat Trailer With 2013 Ford F150 w/ OEM 7-way
  • Rather than using a 4-pole to 5-pole adapter such as # 47515 or # 20036, with the extra wire that needs to be tapped into the reverse light circuit, a 7-way to 5-pole adapter like the # A75TB would work much better. If the 7-way/4-pole connector on your truck is factory installed, the center pin of the 7-way should already be wired to the reverse lamp circuit of the vehicle. You can test this by having a helper place the transmission of the truck in reverse (while stepping on the brake,...
