Wire your vehicle and get the signal lights required for flat towing without having to splice into your wiring with this custom, plug-in harness. Integrated diodes prevent feedback from RV for safe operation. Wires as combined lighting system.
Features:
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 behind your car's tail light assemblies. 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.
Your vehicle ordinarily operates on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, this means that your vehicle will have amber turn signals.) This is referred to as a "separate lighting system." When you hook up for flat towing using this harness, however, your towed car's lighting system will operate in a combined fashion. 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 - with separate lighting - when not hooked up to your RV.
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.

Wire your vehicle and get the signal lights required for flat towing without having to splice into your wiring with this custom, plug-in harness. Integrated diodes prevent feedback from RV for safe operation. Wires as combined lighting system.I installed this harness in my 2013 Honda Fit. The installation was simple. This option uses the brake light for the turn signal vs. utilizing the dedicated amber bulb, but it works just fine. I also have a Roadmaster Even Brake that did require the brake switch relay for this setup to work properly since the brake light and turn signal uses the same bulb.
I have made purchases for two different vehicles. Both were used for four wheel down towing. Each time etrailer gave me correct information on the products and promptly shipped and delivered them. Best of all they fit correctly and no surprises. I will use them again.
Arrived on time. quality made product and easy to install. I actually ran the 4 pin connector wire to the front of my 2013 Honda Fit via the front and rear door thresholds. Once I reached the brake pedal I removed the side panel where the hood latch is located and fed the wire through the rubber grommet hole for the door electric switches. I then used a coat hanger and pulled the wire through the inner fender and down to the front grill. Under the hood I clean it all up with some zip ties. This will keep the line from being exposed to the elements.
After a year of on the road the lights function perfectly
The wiring was easy to install just plug and go
I run one extra wire to my motorhome with a small light on instrument panel to tell me
When the brake lights are on just for me to know if lights are working on car
Easy to install and great price highly recommended
Every thing was plug and play. I won't know if it works until I tow. Had to install RM88400 but that's another review.

Still working well.
The kit worked perfectly with the assistance of etrailer's U-tube tutorial. The hardest part of the job was finding a wire route under the car since there are very few fastening points for the cable ties.
Product worked great. I chose to route the wiring inside the vehicle under door trim. It was actually pretty easy. I went through the firewall where the large bundle goes through above the brake peddle for a very clean install. Super easy install in the back.
Very easy to install. Fit my 2012 Honda Fit perfectly. One year later it's working perfectly. Everything I've bought from this company I'm extremely happy with.
Exact fit for my Honda Fit for towing. Quality product and arrived quickly.
Thank you
Easy installation!!
