Wiring Your Towed Car with Hopkins

Wiring your car for flat towing has never been easier. No more testing wires or splicing into your electrical system. No need to painstakingly position multiple diodes beneath your vehicle. No worries about voiding your warranty. With this custom-fit towed vehicle wiring kit from Hopkins, all you have to do is plug the harness into your vehicle's existing wiring, which is located at the rear of the vehicle. No cutting, tapping, or splicing is required.


After plugging in the wiring harness, use the included bracket to mount the 4-way flat connector at the front of your towed car. An extension loop (sold separately) is required to connect your towed car to your RV.


Separate vs. Combined Lighting Systems

Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system." When you hook up for flat towing using this harness, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.


Do You Need a Brake Light Relay?

Because this harness wires your vehicle as a combined system, 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.

Very easy to install but watch the video on the website, the connector is not as pictured or as located in the written directions that come with it. It literly took longer to run the wires along the frame rail and zip tie them to make the connections. I used the black 4 way holder and attached it to my bumper bit i don't like it, if i was to do it over i would just hide it behind the license plate. 2018 F150 XLT 4x4 718913

My daughter moved the package indoors while I was on vacation. I did not open the package until 9 months later when I first needed it. Part of the components were missing. The box was damaged in transit. etrailer went above and beyond to insure that I received the parts needed to use the unit. Great customer service. I am a very satisfied customer. etrailer is a pleasure to have as a supplier. They worked with me when they were not bound to do so, which is a great quality to have these days. More companies should treat their customers like this. 596475

Very happy with etrailer for the purchase of a Blue Ox tow bar with needed hook ups for lights, etc and an Air Force One Brake system for my 2018 F150. Crystal did a great job of comparing options and matching pricing from across the web. She offered free installation. The Installer, Shane was awesome, I wanted all hookups hidden by the front plate on the F150 when not towing, Shane came through and then some. Finally, the manager Robert was excellent on follow-up as we had some air leak once we got home. etrailer stood behind everything and follow was exceptional. Very pleased! 553938

    We've actually heard of this issue before. You can thank one of our tech support guys for finding a simple solution for this. Even Hopkins wasn't aware of it. First of all the harness is just fine and you didn't install anything incorrectly on your 2018 Ford F-150. Technically, you can just keep towing your truck as is and you won't have an issue other than the lights look weird. Like you said, your F-150 has two bulbs in each tail light for the turn and brake lights; one on top...

    The Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56009 is a fit for your 2018 Ford F-150 but is used for the purpose of sending power from a motorhome to your tail lights when it is towed. That is not the correct fit for what you are seeking to accomplish. To give you the ability to utilize the LED strip at your tailgate I recommend the Reese # 74682 if you have the factory 7 way for a clean connection, but it sounds like the computer may still disable your sensors....

    For help with wiring up the 6-Way I have included a picture that shows how both a vehicle side and trailer side 6-Way are normally wired. On a 6-Way the 12 volt power wire could be attached to the center pin or the pin in the 10 o'clock or 2 o'clock position (depending on which side you are looking at).
