2009 Jeep Compass - Roadmaster Universal Hy-Power Diode Wiring Kit

  • Diode Kit
  • Splices into Vehicle Wiring
  • Roadmaster
  • Tail Light Mount

Features:

  • Connects your RV's tail, brake and turn signal lights to your towed car's lighting system
  • Works with 2-wire and 3-wire lighting systems
    • 2-Wire systems (aka combined) have the stop and turn signal sent along the same wire
    • 3-Wire systems (aka separated) have the stop and turn signals sent along different wires (typically indicated by amber turn signals)
  • Prevents electrical feedback and the damage it can cause to your vehicle's electrical components
  • Kit includes:
    • (4) Hy-Power diodes
    • Molded 4-wire electrical cords - 30' long
    • Power cord - 6' long
    • 4-Way flat wire connectors for both the vehicle and RV

    • Ring terminal
    • Plastic loom - 3' long


Specs:

  • Max amperage: 85 amps
  • Max voltage: 24 volts


Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn lights. Wiring converter kit (154-792-118158) can be purchased instead if you want to retain separate turn and brake signals.

Work as discribed. The first time for me to use the universal kit and was a little worried about the outcome but I followed the instructions and it works great. The hardest part was routing the wire around the front end area. Wire was just enough, I recommend starting at the front end and route the wire on the passenger side. This is the side of the motorhomes 7 pin plug. Remember to stay away from the exhaust (on most trucks as mine is a Chevy 1500). Product was received within 3 days of purchase which works for me. I give Etrailer 2 thumps up for great service once again. 511182

2009 Smart fortwo

I installed the wiring harness yesterday and it took about 4 hours. Thats actually 4 hours of work, in reality it was more like 6 hours but most of the time was trying to figure out how to route the wiring which is not the fault of the harness. Everything worked as advertised with no gotchya's or any issues which was really surprising. I installed it on a 2009 Smart fortwo Passion which I am towing behind my motorhome. My advice for anyone using this is take your time, read the directions carefully before you start and follow them step by step and you should have no issues. 281855

Weve put about 15,000 miles on the MHcar since installing the wiring harness and have no issues what so ever which when towing is a very welcome relief. I am very happy with your product and would highly recommend it.

This isn't the first time I've installed a wiring harness and this one was a nice one (I thought). But I am having problems with the right light (both brake and running light). I've tried calling and talking to your customer support with no answer! I've found if I turn on my lights, at least the running lights all work (but not the brake light or turn signal). I'm thinking it's a grounding problem, but haven't been able to fix it so may have to try someone else's wiring harness. 608773

  • Wiring Diagrams for 4-Diode Flat Towing Tow Bar Wiring Kit RM-154
    I believe you are talking about the diagrams that are lower on the product page, below the description and specs, for # RM-154. There are 4 of these diagrams. I have included a picture that shows them all for you. Please note that the diode kit is not recommended if your 2015 Ford Edge has LED tail lights. I have included a link to a video showing an example installation for you. If your Edge has LED lights I recommend EZ mount light kit # EZT20B which will bypass the factory wiring...

  • Can an AWD 2015 Ford Edge be Flat Towed Behind a Motorhome
    I did some research on your 2015 Ford Edge and it looks like as long as you have a V6 engine in your AWD Edge you can flat tow it without any speed or distance restrictions. Ford does recommend starting the car and letting it idle for at least 5 minutes for every 6 hours of flat towing though. You will need to consult the owners manual for full procedures. For a base plate kit you will need the part # RM-524444-5. In addition to the base plates, you will also need a compatible tow...

  • Wiring Harness For Lighting When Flat Towing 2015 Ram 1500 with Motorhome
    For lighting you can use the bulb and socket kit, # RM-154, and not have to worry about cutting and splicing into the vehicle wiring. This Diode Kit allows you to use your vehicle's tail lights and wiring system while preventing feedback from your motorhome. A 4-Pole flat loop is included to connect your motorhome to the Ram. I have included an installation video of this diode kit for you to check out. The Ram is a 2013 but the installation will be similar.

  • Recommended Flat Towing Wiring Harness for 2000 Jeep Wrangler Towed Behind Motorhome
    I'd recommend the Hopkins flat towing wiring harness, part # HM56202. The harness is a plug and play installation, with no cutting or splicing required. You'd simply locate the point behind the taillight assemblies where the factory plug connects to the taillight. You'd unplug that connection, and plug the Hopkins harness inline at that connection. The connectors with the yellow wire plug inline on the driver's side, and the connectors with the green wire plugs inline on the passenger side....

  • Parts Recommendation for Flat Towing a 2014 Fiat 500L
    I pulled up a copy of the owners manual for a 2014 Fiat 500L and found that the manual transmission vehicles are okay to flat tow as long as you put the vehicle in neutral. You need to check your owners manual to double check this. The first component you will need to flat tow your vehicle is a base plate kit. For that I would recommend the Roadmaster Base Plates # RM-522014-5. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental...

There are 5 major components needed to flat tow a vehicle: base plates, tow bar, safety cables, lighting, and supplemental braking.

There are other items needed to flat tow your Jeep: base plates, tow bar, safety cables, lighting, and supplemental braking. For base plates I recommend the Roadmaster XL base plates # 1439-1.

  • Parts Needed to Flat Tow a 2012 Fiat 500 Lounge Behind a Motor Home
    The bulb and socket kit # RM-155 is one of the recommended tow bar wiring harnesses for your 2012 Fiat 500. But the only way to know for sure if there is space is to drill a tiny hole in the back of the tail light assembly and then use a depth gauge (straightened coat hanger) , push it in the hole until it stops, mark the depth on the hanger, then measure that distance. You will need at least 2-1/4 inches. In addition to the wiring you will need base plates, a tow bar, safety cables,...

  • How to Wire a 2015 Ford Edge SEL to be Dinghy Towed
    Dinghy wiring the 2015 Ford Edge SEL model is quite a bit different than normal diode wiring because Ford combined the stop, turn and taillight signal on the same wire that goes to the rear facing LEDs in the taillight. To make the # RM-154 kit diodes work properly you will need 2 resistors rated for 50 ohms and 10 watts for LED tail lights or 2 rated for 5 ohms and 10 watts for incandescent tail lights, available from a local electronics supply store. You will also need to wire the...

  • Recommendation for Flat Towing a 2012 Chevrolet Equinox Behind a RV
    I checked the Owner's Manual for a 2012 Chevrolet Equinox AWD and it states that this model vehicle can be both flat towed or trailer towed behind a RV. If you choose to flat tow, then there are many components that are needed to safely flat tow vehicle behind your RV. You will need base plates, tow bar set-up, safety chains, a lighting solution and a supplemental braking system. Some applications also may need a high-low adapter to make sure the tow bars are level when towing. For...

  • Flat Tow Wiring Recommendation for a 2015 Jeep Cherokee
    First thing you want to do is test your 7-pin with a circuit tester like part # PTW2993 to determine if it has separate or combined trailer wiring. Most likely if you have a standard 7-way at the rear of your RV it has combined circuits so that it would be compatible with most trailers. Use the chart I attached to compare what you have to what the standard wiring patterns are. For a diode tow bar wiring kit you would want the # RM-154 and then the 7-way to 4-way adapter part # PK12716. If...

  • Installation Instructions for Installing a Diode Kit for Tow Bar Wiring
    Sounds like you are trying to use a diode kit like the Roadmaster Diode kit part # RM-154 to install tow bar wiring on a vehicle with separate function taillights. Running the wiring kit to the front turn signal of the tow vehicle wouldn't work because it would only cause the front blinkers to illuminate. This would be pointless since it's the back lights you want to illuminate. The diodes of this kit prevent backfeeding, so the front lights would illuminate but not the back. To see...

The next two options are more permanent for frequent flat towing. The first option is a diode kit, # 154-792-118158.

If your new lights have this issue, then I recommend getting the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 # P230004A-2 which will solve that issue.
