2004 Acura TL - Curt Universal Tail Light Wiring Kit for Towed Vehicles

  • Wiring Harness
  • Splices into Vehicle Wiring
  • Universal
  • Tail Light Mount
  • CURT

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 Acura TL's existing wiring with the included connectors.


Features:

  • Lets you connect your RV's tail, brake and turn signal lights to your towed vehicle's lighting system
    • Provides 4-way flat plug at front of towed car to connect to motor home
  • Wires in quickly and easily
    • Splices into vehicle's electrical system with included butt connectors
    • Color-coded wires with wiring guide for easier installation
  • Integrated block diodes isolate sensitive vehicle electronics from RV signals
  • Includes harness, 4-flat extension, mounting bracket, and hardware
  • 1-Year limited warranty


Wiring Your Vehicle

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.


Do You Need a Brake Light Relay?

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.

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.

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.




by:

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.

You mentioned in the review that it was not what you had expected and I wanted to see if you could explain in more detail?
-- Etrailer Expert Jenny N - 04/27/2022
Inadequate diodes, extra unnecessary wires for my application, I realize it’s universal, but not what I expected.
-- comment by: Robert - 04/27/2022
How were the diodes not working for you?
-- Etrailer Expert Jenny N - 04/27/2022
When I had the Invisibrake installed, we thought we could tie into the harness, that back-fed to the Invisibrake and locked up the brakes. We then replaced the diods, and everything worked as designed.
-- comment by: Robert - 04/27/2022


by:

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.

  • Will Curt Universal Tail Light Wiring Kit C63CR Work On 2017 Ford Fusion Being Flat Towed?
    The Curt Universal Tail Light Wiring Kit # C63CR you were looking at is confirmed to fit your 2017 Ford Fusion Hybrid and would be a great option to power your lights while flat towing it. We have not had a chance to install this specific harness on a Fusion yet but I included the installation video on a 2017 Ford Focus for you to take a look at. You will still need a tow bar, base plate kit, safety cables, and a supplemental braking system. If you do not have these let me know and I...

  • Trailer Wire Harness for 2013 can am Spyder ST
    While we do not have a custom wire harness, we do have the Curt Universal Tail Light Wiring Kit for Towed Vehicles, # C63CR. This will work but is not a pug and play solution as it requires cutting and splicing of wires.

  • Are Diodes of Curt Universal Tail Light Kit part # C63CR Designed to be Replaced
    The diodes of the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR that you referenced were not designed to be replaced. They are very reliable though so it's not something you'd really need to worry about. They are under the black wire loom.

  • Installation Troubleshooting of Curt Universal Tail Light Wiring Kit on 2013 Lincoln MKS
    You won't need any type of converter when installing the Curt Universal Tail Light Wiring Kit # C63CR on your 2013 Lincoln MKS. However there is a distinct process that you'll want to follow to determine how this system will be installed that tells you whether you've got a 2 or 3 wire system and how to install the unit. It sounds like you might have installed this in a 3 wire configuration but there is no power on the turn signals. I would start by checking any and all ground wires that...

  • Wire Harness For Towing 2019 Dodge Grand Caravan
    If you are going to flat tow a 2019 Dodge Grand Caravan I recommend the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR. This will link up your lights to match the motor home. It is not a plug in play and requires some wire splicing but it is not crazy hard to do.

  • Troubleshooting Running Light Circuit for Curt Flat Tow Wiring on 2019 Ford Ranger
    That definitely doesn't sound good. The brown wires on both sides of the Curt Universal Tail Light Wiring Kit # C63CR should be sending signals since it's for different tail light sides on your 2019 Ford Ranger. It could be a bad diode but it could also be damaged wiring. I recommend adding 12V power to the 4-Way pin with the green wire and then checking the green wire at the butt connectors to see if the signal gets to the end of the wiring. This tells you if the issue is that diode/module...

  • Tow Bar Wiring For 2020 Ford Ranger & Is Brake-Lite Relay Needed
    We can get your 2020 Ford Ranger set up with a tow bar wiring system, and instead of a wiring kit with separate diodes, I recommend going with an option from Curt: - Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR The Curt wiring kit splices into your Ranger's lights with butt connectors already attached to the wires; it also uses integrated diodes to make it easier to install, and will splice directly into both the left and right turn signal lights and the brake lights....

  • How Does Curt Universal Tail Light Wiring Kit For Towed Vehicles Get Installed On 2017 Ford Fusion?
    To find the correct wires on the taillight connector of your 2017 Ford Fusion to connect to the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR you will need to use a circuit tester like # PTW2993 to test each wire going to the tail lights. Your Fusion has combined wiring meaning the turn signal and brake lights are shared so you will need to find the factory wire that comes on when pressing the brake pedal and connect the red wire of the Curt harness in to that wire.

  • What Wire Harness Will Connect My RAV4 To My Motorhome While Dolly Towing.
    Yes, you can use the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR to sync your motorhome lights to your 2012 Toyota RAV4. This part will make the RAV4's lights work as a combined system while it is being towed. It is legal for the RAV4 to be combined while being towed, even if it isn't when driving. This kit will only work if your motorhome already has a 7 way and 4 way flat since the dolly will take up the 7 way connector on the motorhome. If you only have a 7 way...

  • Tow Bar Wiring Recommendation for 2020 Jeep Gladiator
    For your 2020 Jeep Gladiator we have diode style tow bar wiring kits like the part # RM-15247 which would would great but we do not have any custom fit kit like you may be looking for. I did attach and install video for the # RM-15247 on a similar 2021 Gladiator for you to check out as well. This kit once installed will activate your Gladiator taillights while it's being flat towed and comes with a coiled wire to go between the tow vehicle and the towed vehicle.

  • Will The Curt Universal Tail Light Wiring Kit Also Activate The Brakes On The Towed Vehicle
    No, the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR is just to transfer your turn and braking signals from the motorhome through your towed vehicle so that drivers behind you can see them. To activate the brakes in your towed vehicle you would need a supplemental braking system like the Brake Buddy Select 3 Portable Supplemental Braking System # HM39524. This braking system offers intense, emergency braking or steady, smooth braking in a single portable system. Easily...

  • Does It Matter Which Wire To Tap Into When There Are Two Wires In Each Jack?
    One wire is likely the ground and the other is the power side that you will want to splice into. Using a volt meter like the Performance Tools # PT89ZR you can determine which is the power wire. If you have two powered wires, then yes, it is probably going to the other side and it would not matter which one that you choose.

  • 2017 Kia Soul Flat Towing Requirements And Specifications
    So, in regards to your 2017 Kia Soul, along with # HM47085 and # C63CR you already have, you should not need any more diodes for your vehicle. Since you mentioned your lights stay on after the ignition is turned off, yes, you are going to need a brake light relay kit like the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400. I have not heard of the LEDs being an issue on the Kia Soul, as far as I know. If your lights are not functioning as they are intended you likely have...

This is a universal kit that let's you connect your RV's tail, brake, and turn signal lights to your towed vehicles lighting system.

  • Parts Needed to Flat Tow a 2019 Lincoln Navigator 4x4
    From what I could find in the owners manual I located online you can only flat tow your 2019 Lincoln Navigator 4x4 if you have "Slow Climb Mode". If you have the slow climb mode then you will need at least 5 main parts to flat tow. Those parts are a base plate kit, tow bar, safety cables, tow bar wiring and a supplemental braking system. I have included each of those parts below, along with a brief description of their purpose and a recommendation. Base Plate Kit: This is a custom fit...
