Connect your towed car's lighting system to your RV to activate the signal lights required for towing. This universal harness wires in to your Toyota Corolla's existing wiring with the included connectors.
Features:
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. Each wire - for running lights, brake lights, and both turn signal lights - must be connected to a diode. And don't forget to jump the diodes so that the running light signal is sent to both sides of your car.
Or you could just use this Curt wiring harness. This universal-designed system connects to your vehicle's existing wiring. Simply splice into your factory wiring and connect the labeled wires to your factory wiring with the included butt connectors.
Because your vehicle 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.

Connect your towed car's lighting system to your RV to activate the signal lights required for towing. This universal harness wires in to your vehicle's existing wiring with the included connectors.The labels for the Right Taillight Running Light splice were labeled Backwards, to module and to vehicle were reversed which wasted 30 minutes of time. Beware! etrailer may want to get this right with the vendor or risk a bunch of needless returns.
I have bought off of you before everything was great this is the first time that I received something that was not what it was supposed to be or was used before the papers on the installation were all wrinkled and dirty and had writing on the ends of the wire were all cut and the connectors were not on I called your company and they made it right and gave me back my money except for my shipping and they told me just to keep it it's no good to me but thank you and I am still buying off of you
Easy to install. great how to video on the etrailer site. The video needa 1 slight improvement to make it more clear which socket (upper or lower) on the tailight housing to plug into.
You customer service is fantastic !!
Product worked as advertised. Great service. Thank you.
Easy to install works as expected.
The order took very long to arrive. There was no help tracking where our order was and when it finally did arrive the day before my installation appointment, it was the wrong product and they couldn't use it.
Now I have to figure out how to return the product

I am sorry to hear that. I will have our customer service team reach out to you about return options.
Worst nightmare ever! Our mechanic has a person who wires cars for trailers. He could not make it work ($XXX). We were rushed to get it working, before our big summer trip and a Car Electronics Specialist got it working for us ($XXX). I guess I should have gone with a Blue Ox wiring kit. But nothing but this one was recommended to me.

We do have several options for towing wiring for a 2007 Toyota Yaris. You can see them in the link below.

Great diy product with easy to follow instructions that require only basis tools.
Two mislabeled circuits. One on the left and one on the right. Difficult installation. Took two days to complete and my son who works on aircraft avionics was the person to do most of the install. It works when finally all installed correctly. Lots of metering to get this done. We did a more difficult routing through the car and firewall to hide and protect all the wiring. Also ran an additional wire if we ever add trailer hitch and need power for that install.
Everything needed to wire the tail lights to the rv
The kit was very easy to install thanks to the wire labels and Easy Fast Installation video available online. Now I no longer need the magnetic mickey mouse ear tow lights. Thanks etrailer.

It has worked so well that I have been telling other RVers that tow a vehicle to install the kit. Love youll at Etrailer.

Great product, i just ordered the wrong one.
etrailer was a great resource for me to establish my towable. Always available, replaced a damaged part with no issues. One of the best online large projects I've had. Went into this expecting the usual battle, but they were great.
service was great and very profesional
Package improperly packed. Smaller box crushed by heavier base plate box. Paper dunnage only on top, not separating cartons inside.
Fortunately no apparent damage to product. Will test when installed.
This is a teachable moment for packing department.
Well built, easy to connect & disconnect by myself.
I am glad I spent a little more for a high quality product!
Always the best service.
Awesome and Easy Service!

I am sorry that the harness was labeled incorrectly. I had our Quality team check our stock and made sure that the rest were correct. I know that the right turn wiring on the harness with be the green wire [passenger side] and the left turn wiring on the harness will be will be yellow [drivers side]. The brown wiring on the harness will be the tail lights.
