Video Transcript for Roadmaster Tow Bar Wiring Kit Installation - 2008 Dodge Ram

Today on our 2008 Dodge Ram 1500 Pickup well be installing the Roadmaster Universal Power Diode Wiring Kit, part number rm-154. To begin our install well start at the front of the vehicle where well take a 4-pole connector and secure it to the baseplate. To secure it to the baseplate well use some black zip ties. Then as we route the wiring to the back of the vehicle, well use the black zip ties to secure it as necessary. Keep in mind when routing your wires youll want to stay away from moving components such as steering or suspension, or excessive heat such as the exhaust. With this application well also be able to route the wire into the frame channel to the back of the vehicle where it will assist in helping protect the wire.

To help us get the wire in place through the frame channel, well use a pull wire, or in this case a piece of air tubing. Well feed it through the frame channel, through the access hole here, and out the end of the frame, and then attach our 4-pole wire to the pull wire using some black electrical tape. Now we can go ahead and pull it out the end of the frame. Next were going to go ahead and cut off the other end of our 4-pole wire as it will not be necessary. Then well take the white wire and strip it off the 4-pole wire.

Now well go ahead and cut to length, strip it back, and secure our ring terminal. Well then take a self-tapping screw and secure the ground wire to the vehicle frame. Next, well go ahead and pull off the green wire from the yellow and brown wire. With the green wires pulled back, well take the yellow and brown wire and feed it up behind the drivers side taillight assembly. Next well go ahead and remove the drivers side taillight assembly by removing the two torx bit fasteners.

Then well carefully pull out on the taillight assembly being careful not to break the alignment tab underneath. It may be necessary to use a flat-bladed screwdriver or a plastic trim panel tool to separate the alignment tabs and the plastic fasteners underneath. Well repeat this for the passenger side taillight. Next well need to locate the running, turn, and brake signal circuits here for the drivers side. Note this is a combined system where all three signals will use the same bulb.

Well go ahead and connect them. To gain access to the wiring well go ahead and remove some of the wire loom and black electrical tape. Using a test light well see that the running light circuit is the manufacturers white wire with the yellow tracer, and our turn and brake signal circuit will be a white wire with a green tracer. Now with our taillight removed well go ahead and pull the wiring up that we fed through earlier and cut off any excess. Then well pull apart the wires and strip them back. Next well take the excess brown wire and strip it back as well and route it to the end and back down the taillight assembly. This will be eventually routed to the passenger side along with the green wire. Next well need to install the diodes in line with the manufacturers wiring as well as connect our 4-pole harness to the diode. This will use the diode with the yellow push pin connector from the in side of the diode. Well remove it and crimp it into our two brown wires from the 4-pole. At this time well cut our manufacturers running light wire and strip it back on both ends. Now we can take the blue push pin connector from the diode and crimp them down. Then we can go ahead and connect the diode. The out arrow will point to the socket side of the manufacturers wiring, and the other side will then make our diode plug in line with our manufacturers wiring. Next well add the yellow connector hooking in our new 4-pole harness. Now well go ahead and repeat the same process with our turn signal circuit here on the drivers side. Well cut the manufacturers wire in half and strip back both ends. Well secure our yellow wire and the manufacturers wiring with the blue push pin fasteners from the diode. Again, the out arrow will point towards the taillight socket. Now with all our connections made here on the drivers side, Im going to go ahead and use some black electrical tape to wrap up the wires, clean up our install look, and help keep out any dust, dirt, debris, or moisture. Next well take the brown wire that we just fed back underneath the vehicle, pick up the green wire that we left from our 4-pole harness, route them over to the passenger side and up behind the passenger side taillight assembly. Here we can go ahead and secure them with a zip tie, and then make the connections just as we did on the drivers side. Here on the passenger side, our running circuit is a white wire with a gray tracer, and the turn signal and braking circuit will be a white wire with a yellow tracer. Well go ahead and make our connectors to the diode for that. Now we can move to the right turn signal and repeat the same process. Once again, once we make our connections well go ahead and wrap it up with some black electrical tape. Now we can go ahead and reinstall the taillight assemblies. Now with everything reinstalled, this will complete the installation of the Roadmaster Universal Power Diode Wiring Kit, part number rm-154 on our 2008 Dodge Ram Pickup.

Although I am commenting on this product, I actually would like to comment on the following products. I purchased a brake system, tow bar, base plates and wire harness from etrailer. All of my orders were filled in a timely manner. When I reached out for technical assistance, the advisors were readily accessible. All of the products were installed by me. All of the products were very easy to install by using the video and instructions. 337853

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


Comments

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.

I used this for a Jeep Wrangler, probably one of the easier applications. etrailer cautions us to ensure the ground is proper, and I can confirm this. While I found the proper wires using voltage, the gound I used had too much resistance to allow for proper functioning. It took several hours to track it down. But no doubt, when the electical system gives what appears to be impossible data, it is always the ground. I hooked to the proper ground and it works like a charm. I do recommend using heat shrink tubing on the spade connectors. Also I mounted the four flat connector to the bumper. Curt brackets do not fit the connectors in this package without serious modifications. 192669

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

A bit disappointed to be truthful. This is a generic wiring kit with diodes and wire, not Jeep specific. I am totally qualified to install and did without any problems, pretty much had to figure out the color codes myself for the JEEP lights. The real issue is the lack of any wiring for the license plate lights, required in California and pretty sure nationwide. This is a challenge that is not addressed in the kit. I had to pull access panels off, find and trace the wires, install my own diodes and wire as none are provided for this light in the kit. The basic kit is nice but the lack of provisions for the license plate light are a real drawback and not easily solved. 584025

Great experience, quick shipping, excellent video and instructional references to go along with the products. I did the installation of the product myself and without the text and instructional video's there is no way I would have been 100% successful. These are the extra value add things that make the difference when shopping with etrailer, I will be a return customer. I am using this product with my 2016 Jeep Wrangler towed by a 2014 Fleetwood Bounder motorhome. 339287

Installation was relatively straightforward, and the necessary parts were included in the kit. The installation is not technically difficult, but gaining access to some the wiring was somewhat irritating because of the assembly techniques used in modern vehicles. Be prepared for somewhat tedious digging around to get to the wires, and pull enough slack to work with them. Once again, a few extra plastic automotive fasteners and automotive cable fasteners came in handy. They're available at a decent hardware store or Home Depot-like store. 63823

This wiring kit worked marvelously. I'm pretty handy but electrical things can still be a bit scary for me. I got a little help from the good etrailer people, watched a bunch of videos and finally looked at the wiring diagram sent with the kit. Wiring diagrams are not always as straight forward as I would like but this kit has a very good one. I have bought a handful of products from etrailer and consider them to be a cut above.

Comments

The vehicle that I installed the wiring kit in met a tragic death last summer. The new tow vehicle also needed the same wiring kit. The kit is very complete and the instructions are great. Now, think about this........etrailer contacts customers a year later to follow up on their products. Makes you think they actually care about their customers and the products they buy. Almost unheard of in our times.

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

Wired a Chevy Colorado for towing behind a Motorhome. Was using wireless tow lights. Was always a challenge to place the lights on the rear bumper. Plus used untold quantities of batteries. Now just plug & go. Wiring the harness kit was real easy. Just follow step by step instructions. Only deviation was the clips with the kit crimp onto the wires I soldiered after one came lose. After that have had no problems with all the lights working on the vehicle being towed. Should have done this years ago. 485974

I recommend installing this base plate using Loctite threadlocker # LT37420 to keep your hardware from vibrating loose over time.

If you are using a magnetic tow light set-up, such as # TL21RK, you need nothing else to install the Patriot. If you are using another type of tow bar wiring kit, such as a diode kit like Roadmaster # RM-154 or the Hopkins Tail Light Wiring...

  • Flat Towing Lighting Harness Recommendation for 2015 Ford F-150
  • The wiring is different on vehicles that have trailer wiring and ones that do not come with it at all. We see this on other vehicles that will have connections made under the hood and pre-wiring ran to back of some vehicles and on others all of that isn't there at all. In your situation there is a different style of connector than what the part # HM56009 is compatible with. Your truck has a standard round connector since you have the tow package with a factory 7-way. For lighting you...

  • Flat towing a vehicle behind an RV requires a few items, including base plates, a tow bar and a braking system among others.

  • Recommended Parts to Flat Tow a 2018 Ford C-Max Hybrid
  • There are a number of parts you're going to need in order to flat tow your 2018 Ford C-Max Hybrid, starting with compatible base plates. I recommend the Roadmaster EZ2 Base Plate Kit # 524432-1. For a tow bar I recommend going with the Roadmaster Falcon 2 Tow Bar # RM-520 because of how easy the tow bar is to connect to the base plates as well as its long arms, which make it easier to maneuver when towing; you will also need safety chains # RM-643.

  • What is the Difference Between the EZ4 and EZ5 Base Plate Kits for a 2014 Jeep Wrangler Unlimited
  • Since both the EZ4 # RM-521448-4 and EZ5 # RM-521448-5 base plate kits fit your 2014 Jeep Wrangler Unlimited and have removable draw bars there really doesn't seem to be much of a difference at first glance. However, there are some significant differences that are important to take note of. The EZ5 kit is easier to connect your Falcon tow bar to but does not allow the use of the anchor brackets for sterling cables. Sterling cable anchors will have to be attached to the frame or welded...

  • There are a number of parts needed for you to flat tow a 2015-2018 Chevy Silverado 2500, starting with compatible base plates. The correct fit will depend on if you have tow hooks or not. If your Silverado DOES have tow hooks, you need the Roadmaster MX Base Plate Kit # 3167-3 along with the Roadmaster Nighthawk Tow Bar # RM-676, which I like because of how easy it is to connect to the base plates and the fact it comes with integrated safety cables and LED lights. With this set up...

  • Yes, you can flat tow your 2017 Chevy Colorado so long as it has a Four-Wheel Drive Low setting. There are a number of things you will need to flat tow, starting with base plates. If your Colorado does not have Adaptive Cruise Control, I recommend going with the Roadmaster EZ5 Base Plate Kit # RM-523182-5. If you do have Adaptive Cruise Control or your Colorado is a Z71 Trail Boss or ZR2 model you would need to go with the Blue Ox Base Plate Kit # BX1721. For a tow bar, a great option...

  • Recommendation on Flat Towing Wiring for a 2017 GMC Canyon
  • For your 2017 GMC Canyon, I recommend the Roadmaster Universal Hy-Power Diode Wiring Kit, # RM-154. The kit will work on both 2 and 3-wire lighting systems. The kit includes the 4-pole flat plug, so connecting to your 7 pin to 4 flat cable will not be an issue. As for a battery disconnect, I recommend the Roadmaster Automatic Battery Disconnect, # RM-766. The Roadmaster battery is switch operated allowing for easy engaging on the battery disconnect. The switch can be installed in...

  • Can 2016 Ram 1500 Automatic be Flat Towed Behind an RV and What Parts are Needed to Do So
  • The 2016 Ram 1500 can be flat towed with all 4 wheels on the ground only if it is a 4x4. If you have a 2-wheel drive Ram then it can be towed using a tow dolly with the REAR wheels off the ground. This is in the recreational towing section of the owner's manual, page 711. If you do have a 4x4 then for base plates I recommend # RM-52289-4. And for a compatible tow bar I recommend the 10,000 pound capacity Blackhawk All-Terrain tow bar # RM-422. And for 10,000 pound safety cables I recommend...

  • Can a 2017 Ford Fiesta be Flat Towed With 200 Miles on it and Recommended Parts Needed to Flat Tow
  • I checked an online version of the owner's manual about flat towing for your 2017 Ford Fiesta and although I didn't find anything in there about a mileage requirement before flat towing, it is good practice to get at least 500 miles on a new vehicle before doing anything to or with it. This gives the vehicle a chance to break-in. The manual does say to put about 300 miles on new tires so I recommend going on a little road trip before flat towing your Fiesta. To flat tow your Fiesta you...

  • The Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 is a 4-wire kit that gives you a 4-flat at the front of your 2017 Jeep Wrangler so what you can do is use cut off that 4-way and wire it into the Roadmaster 7-Wire to 6-Wire Straight Cord Kit # RM-98146-7; you are correct a straight wire is a better option than coiled for an all-terrain tow bar like your Falcon # RM-522.

  • Flat Towing Parts for a 2017 Buick Enclave
  • First, let's quickly clear up the warranty issue. According to the Magnuson-Moss Warranty Act, a warranty cannot be voided due to the use of aftermarket accessories, so you will be perfectly fine with whatever wiring kit you desire. As for the base plate, the only Blue Ox which is a confirmed fit for a 2017 Buick Enclave is # BX1708.
