Speaker 1: Today we're taking a look at the Curt Towed Vehicle RV Harness. This product is designed to fit certain years of the Fiat 500. To ensure that this is a fit for your vehicle, you can always use the Vehicle Fit Guide located at this harness is ideal for connecting your vehicle's electrical system to your RV while dinghy towing or flat towing. It features a simple, plug and play design, which eliminates the need for cutting or splicing wires. The harness is custom-fit for your vehicle, so it plugs into the factory wiring harness, which is located behind the driver's side and passenger side taillights. Now these plugs, again they're custom-fit, so they're going to match up perfectly with the ports on the vehicle, and they snap-lock together for a nice, tight, secure fit.

One of these would plug into the factory harness behind the taillight, and then the harness that was connected to the taillight will plug into the unit. So it basically takes one connection and splits it.It's a really nice design, it's very easy to use. The wiring is protected with wire looms, so you don't have to worry about your wiring getting damaged. And then you have plenty of wiring here, because this would need to run up to the front of the vehicle. The four-way flat connector will be mounted at the front of your vehicle, the mounting bracket is included to keep it safe and secure and easily accessible.

Once your harness is fully installed, once you're set to go, all you have to do is plug the provided four-way flat connector from the front of the vehicle to the RV's four-way flat socket, and it comes with the extension to do that.Easy to do, it's a nice design, and again it doesn't require any splicing or cutting into your factory wiring. You will need to make a ground connection, that's the white wire with the ring terminal attached to it. You want to get that grounded to a suitable grounding location, and you can use the included grounding screw to achieve that. And it also comes with a lot of zip ties, you can use these zip ties to secure any excess or slack in your wiring at the rear, and as it runs to the front of the vehicle. Also comes with some cable tie holders and some more hardware to get the bracket installed at the front of the vehicle.

It also comes with a dust cap. This could be applied to cover up the four-way flat connector. That way when your plug's not being used, it's safe and protected.Now this unit, once it's fully installed, it uses your existing taillights from the vehicle, so it uses your vehicle's existing taillights, turn signals, and brake lights, which eliminates the need to purchase additional lighting. The vehicle's lights operate in conjunction with your RV's lights, and they function just like a standard trailer when it's being towed behind the vehicle. It does feature integrated block diodes that isolate sensitive vehicle electronics from the RV's signals.

It comes with everything needed for the installation, so you're going to get detailed installation instructions. You're going to get the harness, you're going to get the four-flat extension, mounting bracket, zip ties, dust cap, and the necessary hardware to get the unit installed.That's going to do it for today's look at the Curt Towed Vehicle RV Harness.

2013 Fiat 500

The cord to the front of the vehicle could be about a foot longer other than that I am very pleased with the package. 640648

- C58911

Plug and play is wonderful. Easy to run wire up to the front. 478835

- C58911

All and all the harness is very good, it took about three hours to install. Everything plugged together fine, the only draw back was the wire lead for the car tail lights could have been a couple inches longer. Going to tow car behind a motorhome and the extra lights will help other people see it. 454567

  • What is the Best Way to Tow a 2012 Fiat 500 Behind a Motorhome
  • According to the owner's manual for a 2012 Fiat 500 with a manual transmission (excluding 500c and 500 Abarth), the vehicle can be flat towed with all four wheels down and dolly towed with either the front two or rear two wheels off of the ground. In regards to which is better between flat-tow and dolly tow, they both have their benefits. If you have a leased vehicle or don't want to make any modifications as you plan to exchange it, dolly tow would be your best option but if you plan to...

  • How to Flat-Tow a 2015 Fiat 500
  • In order to flat-tow a 2015 Fiat 500 with all four wheels on the ground behind a motorhome you are going to need a tow bar, base plate kit, safety cables, tail light wiring harness, supplemental braking system, and possibly a high-low adapter. There may also be a few other smaller components that are needed depending on the options the vehicle is equipped with. For a tow bar, I recommend the Roadmaster Nighthawk All Terrain Tow Bar part # RM-676. The Nighthawk is one of the best tow...

  • Recommended Base Plates to Use with Blue Ox Aventa Tow Bar on 2017 Fiat 500
  • You can definitely continue to use your existing Blue Ox Aventa LX Tow Bar with your 2017 Fiat 500. You will just need a compatible base plate kit for the vehicle. If your Fiat is the Lounge or Pop model I recommend the Blue Ox Base Plate Kit # BX2801. If you have the Abarth model I recommend the Blue Ox # BX2805. Both kits are compatible and will work great with your Aventa LX Tow Bar. If you don't have them already, you will also need a lighting solution and a supplemental braking...

  • Recommended Supplemental Braking System to Flat Tow a 2019 Fiat 500
  • The supplemental braking system I recommend for a 2019 Fiat 500 is the Stay-IN-Play DUO Supplemental Braking System part # SM99251 if the coach has hydraulic brakes or the Air Force One Supplemental Braking System part # SM99243 if the coach has air brakes. The Stay-IN-Play and Air Force One are two of my favorites because they are generally easier to install than most other permanent options. If you will not be installing the system yourself then the easier install means you could potentially...

  • 4-Way Trailer Wiring Harness to Fit a 2015 Chrysler Town and Country
  • To tow a trailer with your 2015 Chrysler Town and Country I recommend the Tekonsha # 118534. It's a 4-way wiring connector to power the trailer's lights and it plugs in behind the van's tail lights. You also need to run a hot wire from the harness to the van's battery and insert the included fuse. I've linked the install details and a video from when we installed it.
