Hopkins Flat Tow Wiring Harness - HM56005

  • Wiring Harness
  • Plugs into Vehicle Wiring
  • Tail Light Mount
  • Hopkins
  • Custom

Plug-and-play custom harness gets turn and brake signals on your towed car with no hardwiring or splicing, and no effect on your warranty. The built-in diodes protect your car from electrical feedback.


Features:

  • Allows your RV's tail, brake, and turn signals to display on your car's tail lights
  • Plugs right into car's connection points - no cutting or splicing
    • Custom designed for your vehicle
    • No effect on your warranty
  • Prevents feedback that can damage your vehicle's electrical components with diodes
  • Provides 4-way flat plug at front of towed car
    • Requires additional harness to connect to motorhome - sold separately
  • Includes wiring harness, mounting bracket, and installation hardware
  • 90-Day warranty


Notes:

  • A brake light relay (RM-88400 - sold separately) may be required if used with a flat tow brake system. (See below.)
  • A wiring converter (118158 - sold separately) and 2 additional diodes will be needed to retain separate turn and brake signals. (See below.)

Combined Lighting System vs Separate Lighting System

Combined vs Seperate Lighting System

A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)


A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.


To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.


Do I Need a Brake Light Relay?

If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

See what our Experts say about this Hopkins Flat Tow Wiring Harness

  • Preparing A 2006 Ford F-150 For Flat Towing Behind A RV Motorhome
    I recommend using the Roadmaster Direct-Connect Base Plate Kit # 495-3A for your 2006 Ford F-150. This fits all models with the exception being the STX, FX4 or Harley-Davidson models. With these mounts you will not need to use a crossbar and will be able to connect directly to the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar # RM-422. The tow bars have a rating of 10,000 lbs and are non binding tow bars that make disconnecting your vehicle easier. Channels are added to the tow...

  • Towed Vehicle Has No Brake Lights On After Replacing Damaged Connector On Motorhome
    The first thing I recommend is to use a circuit tester like part # PTW2993 and test all of the pins on the connector at the back of your motorhome. I do not think replacing the diode is going to be the issue, or you would have had issues with the turn signals as well. If you have the ground attached to a clean, bare metal surface and do not have a current showing on the brake circuit, the harness may need to be replaced. If you show current at the connector, the problem lies either...

  • Recommended Complete Flat Tow System For 2004 Ford F-150
    To use the factory plug ins of your 2004 Ford F-150 found behind the tail lights of your truck, I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56005. This will give you a 4-way flat connector at the front of your truck. For the rest of your flat towing system, I recommend the Roadmaster XL Base Plate Kit - Removable Arms # 495-3A which I suggest installing using Loctite Threadlocker # LT37420. For your tow bar, I recommend the Roadmaster BlackHawk 2 All...

  • Flat Towing Setup Recommendation for a 2014 Ford F-150 STX-4x4
    I checked with Roadmaster and the part # 495-1A that you referenced has been confirmed to fit your 2014 Ford F-150 STX so it would work well for you. The InvisiBrake part # RM-8700 that you referenced has also been confirmed to fit your vehicle. There is a Hopkins wiring harness that will fit your vehicle, but the # HM56005 that you referenced would not fit your truck. Instead you would want the # HM56000. The Falcon Tow Bar part # RM-522 that you already have would work great as well. For...

  • Parts Needed and Guidelines to Flat Tow 2002 Ford F-150 V6 4.2L 5-Speed Manual Transmission
    From my research, this is only true for RWD vehicles. So, as long as your 2002 Ford F-150 V6 4.2L 5-Speed Manual Transmission is a RWD, you can flat tow it as is, without any distance or speed restrictions and no other special instructions or additional parts are necessary. If you were unable to find this in your owner's manual, I highly suggest confirming the above information with a local Ford dealer. To flat tow your truck, you will need a set of base plates, a tow-bar, safety cables,...

  • Equipment and Modification Needed to Flat Tow 2000 Ford F150 Behind RV
    According to my research, your 2000 Ford F150 would require a driveshaft disconnect in order to be flat towed without damaging the transmission. Once a driveshaft disconnect has been installed, you'd need a base plate kit, a tow bar, safety cables, an electrical connection to power the vehicle's taillights and a supplemental braking system. I really like the Blue Ox base plate/towbar systems. They are very well thought out, and I find their base plates to be easier to use. For a base...

  • Can 2007 Ford F-150 Be Flat-Towed With Electric Winch Installed
    When installing base plates on your 2007 F-150 the base plates will be installed in the location where the tow hooks are and the tow hooks will be permanently removed. I was unable to determine how the Winch support you have on your truck is mounted but you can look at the attached installation instruction for the base plates to see if there will be an issue with both installed. The base plate kit I recommend for your F-150 is part # BX2169. For a tow bar I recommend the Blue Ox Avail,...
