Video Transcript for Tow Ready Wiring - Wiring Adapters - 20036 Review

Today we're going to be reviewing part number 20036. This is the Tow Ready 4-pole to 5-pole trailer wiring adapter. This wiring adapter is going to change the 4-pole flat on your vehicle into a 5-pole flat. The length of the actual harness is going to measure 20 inches from end to end, and then the length of the blue wire that it comes with to make the connection into the reverse light function is going to be 60 inches. This unit is rated for 7.5 amps per circuit. It's going to come with some zip ties to help secure the access wire up and out of the way.

The 60-inch blue wire is going to get spliced into the reverse light wire on the vehicle. It's very easy to do because they include this quick splice wire connector. Then the connector on the blue wire, the plug in one, is going to connect to the blue wire coming from the harness. So those will go in together, which is then going to supply power over to the new, 5-way flat, and then you're going to have all the power you need. Once everything is connected, you're all set and ready to go. Again, this one right here is going to measure 20 inches.

And then the length of the blue wire is going to measure 60 inches. And it's a very easy system to install and get connected. That's going to do it for our review of part number 20036. This is the Tow Ready 4-Pole to 5-Pole trailer wiring adapter. .

This was exactly what I needed. Our Nissan Pathfinder came with a 4 prong plug already installed, but our new boat trailer has a 5 prong plug. This fit perfectly, works great (already used it this past weekend) and the installation was easy, thanks in part to the instructional video included on the product page. Would definitely recommend to anyone that needs to go from a 4 prong to 5 prong for your trailer. 18183

Which wire did u crimp on to for your Pathfinder? Could u tell me the colour pls. Thanks.

We've sent Chris an email to let him know about your question. Remember to always double check a wire with a circuit tester before connecting. Wire colors can change on the same model, even in the same year so the colors may not be the same. Just check before splicing.

Simple install on my Jeep JK. Tapped the reverse light lead wire and harnessed all the wires in flex conduit. Tie strapped it all under bumper. Can either use 4 or 5 pin trailer. 234357

This is for a 2014 Jeep Cherokee Latitude. It took me a little extra time as my helper was a 5 ton floor jack and it supported the receiver and if only my right foot had fingers it would have helped a lot. Loading the bolts and plates into the frame was a snap, I left the fish wires on the bolts and that helped a lot and I didn't lose a bolt into the frame,you must leave the exhaust hanging to get to the rear bolt closest to the exhaust curve just before the mufflers I didn't and it was a bear to torque it. Also after I cut the opening on the bottom of the bumper and already had torqued the receiver I had to pry the bottom edge over the receiver there was no other way to get the hitch up inside not enough forward space to get it to slide up and in. Other than that it was a snap. Now for the wiring harness, went well had a bit of a time getting the connectors up to the tail lights even with all 4 screws out and a little bit of play I had to pry the plastic support away from the body to get the connectors through. That was for the 4 flat, for the power for the harness I have a rig runner 4005 from Powerwerx for all my power as I am a volunteer Fire Fighter and have all the goodies that goes with it and every thing runs fine. For the 5 flat all I had to do was find and take out the backup bulb in the tail light and test to find which wire was hot. And then it was over and done put it all back together and drive away with my trailer. Sorry no picture it looks just like the factory/dealer put it on. Ray H 145521

This 4pole to 5 pole adapter works exactly as advertised. Now my trailer brakes don't lock up when backing up on an incline. Took about 10 minutes to install and corrected my problem perfectly. I especially like the "how to" videos! 87338

Adapter 4-pole To 5-pole Flat - works as described. Installed on 2013 Chrysler Town & Country. Connected blue wire to left rear light harness. Strongly recommend using a 12v tester for this install, as visual diagnosis can be wrong. Deduct one star because 5-plug has no cover and is susceptible to road grime. My solution is to leave original 4way plug with cover underneath the vehicle and connect 5plug adaptor only when towing boat. 125129

Harness perfect for the application, adding 5th conductor for recent Highlander trailer plug. How-to video totally helpful. I was impressed that you put together such a complete video for such a small part. That led me to buy from you instead of competitors. 254934

Easy install on new F150. The hot wire for the back up light was the same color blue as the blue on the back up adapter. Tip: I hard soldered my connections where I spliced. Then use shrink wrap. That is a superior install. Crimp on connectors almost always fail over time. 540560

I have been using adapter #47515 to convert my 4 pole vehicle to my 5 pole trailer plug. The extra wire was necessary to operate the solenoid on my surge brake trailer. It worked ok, but because the wire came into the 5 pole plug at a right angle, the wire seemed vulnerable to bending and then breakage. This product has the extra wire coming straight out the back to alleviate the bending/breakage concern. So far it has met my expectations. 272943

Had to purchase the part for a boat trailer hook-up. etrailer was the only place and first place we looked. Our local trailer dealer did not stock the part, so having purchased an item from etrailer before, we chose the company to purchase what we needed.

Product does exactly what you'd expect -- make my funky 5 pin trailer work with my four pin Toyota Highlander. I am sure that its a good idea to have engineered the safety brake but taping the interlock gets old. Product is well made, the instructions were very clear and it was well packaged and arrived quickly. Importantly, customer service reached out to me to make sure it arrived and that I was happy. That's impressive too. 496155

This seems to be a good option for an adapter to get a 5 wire trailer connection. The single wire for the back up light connection is odd to secure to wire harness so it don't get damaged from dirt. The socket could have a cap to cover so dirt can not get in it when not in use. 475524

  • Using the AutowBrake Brake Controller with a 1999 Toyota 4Runner and a 1997 Toyota Previa
  • Installing the Autowbrake brake controller, part # 3430001, doesn't actually requrie you to make any changes to the 4-way connectors on your vehicles. All it needs to function is to be wired to the proper wires on the trailer and a constant power source. If you want, you can wire the Autowbrake's power wire (the black wire) to the trailer's running lights and then it will have power as long as you tow with your lights always on. The downside to this is you will then always be drawing...

  • Recommendation to Install 5-Way Connector on 2018 Toyota Highlander
  • It sounds like you are needing to install a 5-Way connector on your 2018 Toyota Highlander, which will allow you to tie the reverse light to the 5th wire to activate the electric lockout on your boat trailer's actuator. The easiest way to do this will be to first install a 4-Way connector on the vehicle. If your Highlander does not have the factory tow package (that would have a converter under the dash), I recommend the Tekonsha T-One Vehicle Wiring Harness # 118449. If you do have...

  • Towing Package for a 2008 Honda Odyssey
  • The trailer hitch I recommend for your 2008 Honda Odyssey is the Draw-Tite Max-Frame # 75270 because it doesn't require any fascia trimming (like the etrailer and Curt might). This, as well as the other trailer hitches, exceeds the weight ratings of your Odyssey so you can be confident that you are getting the most out of the trailer hitch. Be sure to check the weight ratings of your Odyssey in your owner's manual and keep from exceeding it. To finish out your towing setup I recommend...

  • Best Trailer Hitch Receiver for a 1999 Buick LeSabre
  • We currently only have one trailer hitch receiver for your 1999 Buick LeSabre which is the Draw-Tite Trailer Hitch Receiver part # 36216. This option will give you a Class II hitch with a 1-1/4" receiver tube opening. I have attached an installation video on a similar 1997 Buick LeSabre for you as well. If you can tell me what you will be using the hitch for I would be glad to offer some additional recommendations for you as well.

  • Adding a 5-Way Flat Trailer Connector to a 2017 Toyota Highlander Limited with Tow Package
  • First I have to tell you that the 2017 Toyota Highlander warranty cannot be voided if you install or have someone install an aftermarket part. Now if that part was to cause a problem on the vehicle then the repairs would not be covered. With that said I would agree that if the vehicle is pre-wired for a trailer connector you would need an option that doesn't come with a converter. In order to get a 5-Way you would first need to install a 4-Way using # 56042. Then you would need the...

  • Do I Need To Install A Brake Controller To Activate Or Deactivate Surge Trailer Brakes In Reverse?
  • Great question. Let me cover brake activation first. If you wish to have active braking on a hydraulic system when backing up, you would need to have Electric over Hydraulic brakes and not a surge brake coupler. Surge brake couplers do not allow active braking when in reverse. To add the electric over hydraulic system, it will require a brake controller like # 39523 and an electric over hydraulic brake actuator like the HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc...

  • Recommendations For Towing A Bayliner Boat Trailer Using A 2015 Dodge Durango.
  • The plug really doesn't matter based on the trailer hitch. The functions you want will determine what the best fit will be for your application. To have all the functions available to you, most people get the 7-way trailer connector. This will give you the turn/brake/running/ground/reverse/brake controller/12V power functions. This is what comes with most trucks that have a factory tow package, however, if you just want a 5 way flat I will give you that option as well. For your 2015...

  • We do offer 4-pole trailer wiring kits for the 2017 Honda Pilot, shown on the linked page, such as # 118760. This is the kit I recommend since we find Tekonsha wiring products to be very reliable. 4-pole type trailer wiring carries three lighting circuits (plus a ground, on the 4th pin) but does not carry any other type of trailer signals such as power for electric trailer brakes. The circuits on a 4-pole are for running lights (brown wire), left turn/stop lights (yellow wire) and right...

  • 2013 Jeep Wrangler Unlimited 5-Way Trailer Wiring Harness Recommendation

The part # 118416 installs by attaching inline with the taillight connectors of the Jeep and then the # 20036 plugs into the 4-way and allows you to run the 5th wire to the reverse light circuit of your vehicle and you have a functioning 5-way.

Once that is done I then recommend cutting off the 4-Way Flat connector on your trailer side and installing the Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 using Butt Connectors # DW05744-10 to secure your connections (wires on the 5-Way are labeled).

You'd have to tap into the reverse light circuit of the vehicle by tracing the wires that lead to the reverse lights and testing the wires for voltage when the reverse lights come on.
