Wiring Your Vehicle with TrailerMate

Typically, wiring your car for flat towing is a tremendous chore. You have to position and mount multiple diodes beneath your car and then splice into the car's wiring. Before cutting and splicing, though, you have to use a circuit tester to identify each wire. This must be done for the wires carrying signals from your running lights, brake lights, and both turn signal lights. And don't forget to jump the diodes so that the running light signal is sent to both sides of your car. could just plug in the TrailerMate wiring harness. This custom-fit system plugs into your Jeep Wrangler's existing wiring harness, which is located behind your car's tail light assemblies. No cutting, tapping or splicing is required. The wiring around the plugs is encased in durable convoluted tubing, making it easier to handle and safer to route as well.

After plugging in the wiring harness, use the included bracket to mount the 4-way flat connector at the front of your towed car. Then hook up to your RV with the supplied wiring extension, and you're good to tow. Note: The extension included with this system requires that your RV have a 4-wire flat trailer connector. If your RV has a 7-pole round connector, or another type of connector, then an adapter is required.

Do You Need a Brake Light Relay?

Because your Jeep Wrangler has a combined lighting system - wherein the brake signals and the turn signals are carried on a single wire - a brake light relay (RM-88400 - sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then you need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

T-Connector Function for Towing a Trailer

When you're not flat towing your car, the TrailerMate wiring harness can remain on your Jeep Wrangler; it will not interfere with the electronics. And if you ever tow a trailer with your car, you'll be wired and ready. The TrailerMate system comes ready to accept 4-flat wiring (TM85330 - sold separately) at the rear of your Jeep Wrangler so that you can hook up a trailer quickly and easily. Just plug in the add-on 4-way trailer connector, and you're good to go.

Etrailer has the best customer service of any company I have dealt with in several years. I received a call from etrailer that the wiring harness was back ordered and the company that made the harness could not give a shipping date. I was offered to change to another harness (Hoskins) but I decided to go with the TrailerMate since I had prior experience with that brand. I was kept informed all through the ordering process and received the wiring harness in about two weeks. The TrailerMate harness is very easy to install and worked perfectly. The instructions are clear and made the installation easy. There are two way to run the wiring from the rear of the vehicle to the front. Since I was installing on a 2014 Jeep Wrangler that will be going off road. I wanted as much protection as possible on the wiring. I opted to run the wiring through the frame rails. The instructions say to use a fish tape and pull the wire. Since I didn’t have a fish tape and didn’t want to buy one for a one time use. I used an old 12 ft metal carpenters tape. There is an opening near the rear where the wire comes from the harness and another near the front driver’s side wheel. Run the tape through the front opening to the rear (you will probably have to giggle it around to get it over the rear part of the frame). At the rear opening pull the tape and fasten the harness wire to the ruler tape and then pull the tape to the front of the frame where to can route the wire to the front connection point. 123105

Great product, no wiring or splicing to do, just plug it in and it worked the first try, It was a little tough routing it through the frame and then feeding it around the engine compartment where it would be safe, cutting the hole near the right tail light required some special tools that some folks might not have? I'm a retired Flight Test Mechanic so this was a piece of cake for me. Sense it's all hidden behind the tail lights and in the frame, photos of the finished job won't show much 93575


It still works perfect, no problems, I would definitely recommend it to anyone wanting to tow a vehicle,

In general I am very pleased with the product and installation information. Some of the installation information could be more defined. such as were to run the wiring after it come out of the frame rail. The wires that run between the rear tail lights could be about 12 inches longer. I do have a question as well; when I ordered the kit I asked if the harness provided blocking diodes within the harness and was told it did. I have not connected it to my RV yet and wanted confirmation about that? If it doesn't I just wasted 75 Dollars on my purchase because I will then have to modify the circuitry to prevent an electrical problem from occurring! 110596


The diodes are built-in. If you cut back the plastic wire loom, you can see where the are splice and heat-shrinked in line. Typically, they will be found closed to the tail light connectors.

  • The TrailerMate # TM781124 and the Tow Ready # 118416 can indeed be used together. However, if you are using a supplemental braking system in your Wrangler Unlimited, you will need to install diodes inline with the TrailerMate harness to prevent backfeeding into the RV wiring.

From what I could find, the 2013 Jeep Wrangler does not require a brake light relay or stop light switch in order to use a supplemental braking system. A 12 volt outlet kit # RM-9332 is recommended to power the braking system. I have included a couple of helpful links on flat towing for you.
