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.

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

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

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

Very useful and easy to install along side the 4-flat that I installed at the same time. The toughest part was locating the reverse light wire. This was of better than expected quality and the wire was just the right length for my 2006 Jeep Commander. 204511

The adapter works great. The installation on a 2005 Subaru Outback is a bit more difficult because the backup lights are located on the liftgate. Still only took about 1/2 hour. Now I just need to find a cover for the 5-Pole! Al 11001

Product is perfect. It works as advertised. I am able to hook up my motorcycle cargo trailer and motorcycle camper, if I need to pull them behind my 2013 Ford Edge. 154146

Received the adapter very quickly. The on-line tutorial was great and was able to install the adapter on my Ford 150 in less than 5 minutes. Works like a champ. 68147

Easy quick fix for 4 to 5 pole on car wiring. Had to come thru hatch back on 2014 Highlander could have used a little longer wire but had some available 213391
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

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

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
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
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
Part arrived in time and everything's cool. The #1 thing I like about etrailer.com is that I can simply email them my questions and they reply back with all my options. Will be doing that again in a month for the next trailer item I'll be needing soon. Thanks. Todd 114450
Ordering was easy; shipment was quick; the part arrived as expected and worked great. It was very easy to install. Took all of 10 minutes at most! Thanks! 66804

The 4 to 5 pole adapter was exactly what I needed to pull my new boat with hydraulic brakes. I installed it myself in less than 10 minutes saving me the time and cost of going to an RV or trailer store. 163414

Product was exactly what was advertised and just what I needed to to adapt to a five pin harness on my sons boat trailer. Great, FAST delivery. 159022
by: Mr Larson05/05/2014
The adapter fits perfectly. Thanks for the follow up. We need to test to make sure it works, but if it is a standard setup, it should work 128889
Works fine. I'm not concerned with the reverse light so I didn't even hook up the blue wire, working great as a plug and play adapter. 63582
