2008 Jeep Grand Cherokee - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit

Diode kit allows you to use your Jeep Grand Cherokee's tail lights and wiring system while preventing feedback from your RV. Wires 2-wire and 3-wire systems to operate as a combined lighting systems. Includes 7-wire to 6-wire Flexo-Coil electrical cord.


Features:

  • Lets you wire your vehicle to accept your RV's tail, brake, and turn signal lights for flat towing
  • Wires towed car as combined system so that brake and turn signals travel along same wire
  • Prevents electrical feedback and the damage it can cause to your vehicle's electrical components
  • Diodes powder coated aluminum case is corrosion resistant and provides protection from the elements
  • Brake light relay (RM-88400 - sold separately) may be required if used with supplemental braking system
  • Flexo-Coil cord is resitant to water, oil, chemicals, and has silicone-injected plugs to prevent corrosion
  • Center pin on 6-Way plug wired to 12V power, there are two industry standards
  • Includes: 4 Hy-Power diodes; 30' long, 4-wire harness; wire connectors; cable ties; 1 ring terminal; 3' long plastic loom, 8 ft coiled cord, vehicle mounting bracket, and socket

  • Diode Max amperage: 85 amps
  • Diode Max voltage: 24 volts
  • Coiled cord max length: 8'
  • Coiled cord retracted length: 15"


Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. A wiring converter (118158 - sold separately) and 2 additional diodes (RM-792) will be needed if you want to retain separate turn and brake signals.


Separate vs. Combined Lighting Systems

Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system". When you hook up for flat towing using this kit, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.

Do You Need a Brake Light Relay?

Because this kit wires your vehicle as a combined system, 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.

Video Transcript for Roadmaster Diode 7 to 6 Wire Coil Kit Installation - 2012 Jeep Grand Cherokee

Today, on our 2012 Jeep Grand Cherokee, we are going to be showing you how to install the Roadmaster 7-wire to 6-wire Flexo-Coil Diode Wiring Kit, part #RM-15267. Here is what our RM-15267 kit is going to look like. What we are going to have is a good 30 foot length of wire. This allows us to get from the front of the vehicle where we are going to be mounting our 6 pull plug right back to the vehicle's taillights where we want to send that signal. We've got diodes that are going to present back-feed from the car to the motorhome or from the motorhome to the car so it's a really nice, very well-protected system. Then, we've got the umbilical.

That is going to plug right into our 6 pull on the front of our vehicle and it will go right up to the 7 pull plug on the back of our coach or our motorhome. We've got a small piece of wire loom that is going to be included in there. We've got a bracket that will allow us to mount our 6 pull. Most times, that is going to mount perfectly on base plates itself with one of our short brackets or one of our long brackets, but the base plate we are working with today, it already had one provided to attach so we are going to be using that. It is also going to give us a set of instructions and some zip ties and for anchoring out our ground wire, a small ring terminal. The first thing we want to do is remove the 4 push pin fasteners along the bottom side of our fascia here. Use a screwdriver or trim panel removal tool if you've got one.

Just kind of want to work the center out. Now, on each side, we are going to have this little knob. It's going to be right behind the fascia here, just in front of the tire. We want to rotate that about 90 degrees, we will be able to pull that out and that is going to free that bottom up. We are going to do that on both sides. Now, we will pull out the rivets that are located here and here.

Now, to do this, we can either drill it out. We've got oversized tires here so I can't get my drill bit in here. Use a utility knife to cut it off. I am worried a little bit about scratching this trim piece here with the razor knife so what I am going to do is use a pair of side cutters. I am going to stick my hand up in there right behind it and I am just going to clip it off.

We should just be able to wiggle that there and get it separated and then just pop it out. Now, on our upper rivet here, we are going to have just enough room to get the drill bit in there and we just want to hollow out the center. Then we can use our screwdriver and pop it out. Then, lastly, we will come just behind the bolt we removed and take out the push pin fastener. This is just like the ones we had on the bottom side of the fascia there. They're backed out. Now, we can head over to the driver's side and we will repeat that exact same process. Now that we've got those fasteners removed, we can pull out, right above the little gap on that panel that goes around the wheel well, it is a little trim panel, it is going to have just little pressure clips. You see we will be able to pop that out, that is going to allow us to get a little bit of room in behind there. We will have it pulled out like that and then we can start working out on our fascia corners on each side here. We are going to remove it right along that line. Now, what we will do is reach in behind that matte black trim or whatever color it happens to be on your car and we want to separate the plastic front fascia cover from the fender itself. We will do that just by pulling out. Now, as we pull this down, you'll notice our fog lights are right here so we are going to reach in behind there and disconnect each of the clips. Now, to separate our plugin here on the back of our fog light, we will press in that tab and just kind of wiggle it, that tab right there is what we press. Now, if we are running our wire to the front, we will take it, we are going to run it right over the heat shield on the passenger side of the vehicle, that will keep it protected from the exhaust there. We will pull it on through and then we will go right up over our frame rail there in the subframe rail here at the front, make sure we get out all of our slack there. We will just keep running it up forward. Now, from there, I am going to run it right up just below the coolant tank reservoir. We can run it right over the same direction, our breakaway switch or airline or anything else to be mounted. Now, we can bring it on over where we will be mounting our 6 pull plug. Then, we just want to go through and secure it off in a couple different spots to make sure it is anchored and it is not going to touch anything sharp, hot, or anything that might cause damage. Now, we will also be able to do a couple around this rounded frame tube here. It is going to offer us a really good anchor location. We will have to use some longer zip ties than what came in the kit so you might want to think about having a couple of those on hand. Now the rest of this, we will just let that hang out until we need it to go to the back of the car. Now, lets just separate out our wires a little bit here. We want to strip the end of each one back and if you have decided you are also going to have a charge wire, we will strip it back, twist the ends up, put together either the 4 or 5 wires, depending on your set up. Gather it up, pass it though the rubber boot, slide that up out of the way, and we will bring in the back of our plug. As you can see, we are going to have 6 connection wires here. The center one is going to be our auxiliary, that is the one we are going to mount our charge wire too. Let's go ahead and get that one in place. It goes right in the middle. Slide it in, use a little Phillips screwdriver, we want to tighten that screw down. Now, if we are going to be looking at the top of the plug with that being the flat spot there, that is the top right here. We come to about the 10 o'clock position, that is going to be our ground so that will have the white wire put in. Just to the right of that, is going to be for our trailer marker, that is going to be our brown wire. We are going to skip the next one. That is for our stop. Once we get past the stop, the next one is going to be for our green wire, that is for our right turn. The last one, that will be for our yellow wire. That is for our left turn. Now, we will take a quarter inch bolt and the flat washer. We are going to place that right through. We are going to put a locking flange nut on the backside. If you are using just a standard hex nut, you probably want to put a lock washer on that backside. Now, we are going to take a little bit of black tape and just kind of wrap all our wires up on there on the backside. This part, for a little while, back here, will be visible, behind our fascia. So, it is nice to get it all, at least the same color, get it all wrapped up in electrical tape so you won't have to look at it. We will slide our protective boot back down and place it right over the back. Let's get our bolts lightened up. Now, we will pull the slack out of the wiring there and make sure it is free of any obstruction. A couple more zip ties will help keep everything nice and tidy. Now, we need to get in behind each of our taillights here and we are going to figure out which wire controls what signal. Let's take out our pushpin fasteners on each side here. You are going to see these every time you open that back door so you want to be a little careful with these, you don't want to scratch them up too bad or anything. Pull rearward gently here and get our housing separated from the body of the vehicle. Here, we will see on the backside, we are going to have 2 connectors. You've got one here at the top and one here at the bottom. Go ahead and pull the red tab back on the upper connector and we will get it separated. Then, on the smaller grey connector, there will be a black tab and pull out on that. We can separate that one as well. I am going to set these aside somewhere safe. Without doing any damage to the wires underneath, lets pull back the sheeting that kind of covers those wires up. It is going to expose them so we can get in and test them out. Lets get rid of that. See, we will have 3 wires on this plug. We will separate this one where it will have 2. Now, what we want to do is test out each of our wires. We can see where they run in. We've got a black or a white with orange, a white with yellow, then we've got a black and a white with green. So, we've got the running lights on in the vehicle now. We test in there, there we go. Now, go ahead and turn the running lights off. There they go off and you can see that one shuts off and back on. Perfect. So, we are going to know for our running light circuit, we want that white and orange wire. Lets write that down. Now, we will have them apply the brakes. Okay, let off and back on. You can see with our brakes applied, that is going to be the white wire with the yellow stripe. Finally, we will have him turn on our right turn signal. Alright, so this is what they call the combined system since we are getting both our blinker and our brake light that comes from that yellow and white wire. We will be able to use the signal diode to work both the brake and the turn signal right through there. We won't have to worry about our grey plug. We will be plugging that right back in. We will go over and run that same test on the driver's side, get that written down, and then we will be ready to move on. Now, we will have him turn our headlights on and we can test our plug over here. Should be the same sequence and off and back on. Yeah, you can see here, this time the white wire with the brown stripe is going to be for our running lights, that is the one in the middle. The one on the outside should be for our blinker and brake. Let's go ahead and step on the brake. Alright, that is working fine; off and left blinker. Alright, that is what we are looking for. So, this is going to be a solid white wire that is going to take care of our brake signal and our blinker. The white and brown, that is going to be for our marker lights. Now, while we are up here, something that can really help out in getting our wires up here where we need to work on them, just take like an airline tubing or a piece of wire, anything really. We are just going to poke it down from the top down there to the bottom. Just want to make sure it is a little bit stiff and what that is going to do, is if we just reach in down here, we will be able to find an attachment point so we can connect our wire here and then pull it right on up through where we need it to work on. Do the same thing for both sides here. Right here is where that bundle of wire was, this is where we started running it towards the front of the vehicle. What we've done now is run it back behind the heat shield, all the way around, then we come right across this channel and we have gone up over the fuel tank there to keep it nice and safe. Once it comes out from behind our field tank, using a couple of zip ties to keep it up and away from any kind of moving parts or any kind of moving objects, we bring it right back down, kind of behind the center differential here and this is kind of where we separate things out. Our green and our brown wire, these are going to run up behind our passenger side taillights so we fold those separate here. The yellow wire, we run across, again using zip ties to give it support, to our driver's side. Then, our white wire, our ground wire, we are going to terminate that pretty close here, just add in a ring terminal and get that secured to the body of the vehicle to ground it out. We are just going to run our wiring up over our exhaust there. Now, we can connect our green wire and blue wire. What that's going to allow us to do is to pull this up. As we pull it up, we can work it up over that hump and use a little bit of electrical tape to secure it off there. Now, we can pull our wires on up from the bottom and remember to guide them over the exhaust like we had discussed. What we are going to do is just use a zip tie to help combine our factory and our wires from down below, that is going to keep any slack from being pulled down. Now, we can connect our brown wire in to our orange and white wire here. Lets figure out exactly where we want to put the diode. So, lets cut our factory wire and also cut our brown wire off. Now, we will hang on to our piece of brown wire. We don't want it to go anywhere. Now, we are going to strip all 4 ends back. Now, for our trailer marker lights or our running lights circuit which is gong to be the brown wire, we are going to use the diode that has the yellow spade connector on it. This is going to be used to combine the brown wire that comes from our plug in the front and the brown wire that we just trimmed off. So, we will twist those together, add that large spade connector, and we can get it crimped down. With that connected properly, we will take our 2 remaining spade connectors off there and we will crimp that onto each side of that factory wire. What we are going to have is 2 inputs, so we will have our running lights coming from the RV and our running lights coming from the car. Those will get plugged in and then we are going to have a single output that needs to be plugged in to the side that our plug is on. Now, we need a little bit of rubbing alcohol and a shop towel. We are going to be using this flat area right here to mount our diodes to so lets get that cleaned up well. We can peel that cover off of our adhesive and just put it right down there. The next wire we are going to deal with is going to be our white and our yellow. Lets get that sized up. We are going to be connecting our green wire to that one. Lets get them stripped back and we will add our diode in place. This time, though, we are not going to be doubling up our green wire. Add a spade connector to each of those. Now, we have got our input from our motorhome, input from our factory wiring, out to the the plug that will go to our light. We are almost ready to put our taillight back into position, but what we want to do, is take the tag end of that brown wire and we are going to pass that right back down where we can grab it from the underside of the vehicle. This needs to go over to our driver's side. It is going to send the signal over there, acts as a jumper wire so it brings a signal in from our front plug and its going to allow that to go over to the other side of the vehicle. Now, we will just slide our connections together here. Remember those locking tabs, we want to push in. We will put it right in place. We will just give it a firm push to get it popped back into position and we will use our 2 push pin fasteners, place them right back in, and push in the cord to hold it in position. Alright, nice and secure. With our driver's side situated, lets go ahead and get our ground wire attached while we are underneath here. I am just going to trim it off and run it right up here to the body and ground it out. You might want to hang on to that extra piece of white wire, depending on how you've routed your wire. You might need a little bit of extra to make the connection over there on the passenger side. What we are going to do is strip back the end of our wire there. We can use our provided ring terminal or if you've got a different setup, if you want to use a different style. We are going to use a little bit bigger self-tapping screws, so we are going to use a little bit bigger ring terminal. Slide that on, get it crimped into position. Use our self-tapping screws and start our hole. Once we have got that started, we will add our ring terminal to our screw and get it tightened down. Now, the brown wire that we have run down from behind the passenger side taillight, we are going to take over towards the driver's side. There is a good area right up here between the bumper and bumper supports that we can run it and we won't have to worry about it coming down. We will bring out yellow wire over. Just like we did on our passenger side, we will connect them to our pole wire and bring it on through. Now, our brown wire, that needs to go to our trailer marker light or our running light circuit, that is going to be the white wire with the brown. Just like we did before, just figure out where we are going to position it here. We will trim our factory wire like that and also cut back our brown wire. We will leave plenty extra here so there is room for it to stay behind the housing. We will strip the end of each of them back and add in our diode just like we did for our other side. Then, our white wire is the one that we are going to use for our turn signals. So, we will get our diode added in there as well. I am going to gather up any slack that I might have in that yellow and brown wire so that it doesn't hang down below the vehicle, zip tie it off just like we did on the other side there, tuck those down, make sure they are not going to get pinched here or here. We will just slide our connectors back together here and then get the taillight back in position and we will replace our fasteners. Alright, now we can test out the system and make sure it is working as it should. Now, we want to test out our wiring in 2 different ways. The first thing we are going to do is turn on the running lights in the Jeep. There, we want to see both lights come on on each side. We are doing it in the car itself to make sure everything is still working properly there. Do our left blinker, our right blinker, and our brakes. So, we know that is working fine. Now, we will completely shut off the vehicle itself and we will test it out by plugging it into either the motorhome, a tester, or any other vehicle for that matter that will have a 7 pull plug. I will do a test on our taillights to make sure they work. All right, now we can check our right blinker and our left blinker. Now, we will do our left brake light and our right brake light. All right, looks like everything is working as it should. That will complete our installation of the Roadmaster 7 wire to 6 wire diode kit, part #RM-15267 on our 2012 Jeep Grand Cherokee.

Overall this would be a five star review except for two issues. One being the wire provided was not 30 ft but was closer to 25 ft as I checked before using. I wired the same as the great etrailer video for my vehicle Cadillac SRX and ended up short. Fortunately I had additional wire and was able to complete the run. Secondly, the female spade connectors used on the diodes needed to be tightened as they were not very tight as provided by Roadmaster. These were all Roadmaster issues and of not fault of etrailer. Everything else looked of good quality. 428886

I found the installation video to be more helpful than the written instructions. The toughest part of the installation was routing the wires to the front of the Forester. The video was helpful in figuring out the best path for the wires. 460332

I like the coiled cable in RM-15267 At one time I owned an Airstream travel trailer that had a tow cable. The Airstream did not have a coiled cable and I had to tie it up with bungy cords to still allow flexibility while traveling. That lasted for one season and the bungy cords stretched out and the cable started touching the road, scraping off the insulation! The coiled cable in the RM-15267 prevents the cable from dragging on the road! 446459

Everything installed without any issues. I'm very particular so it took 2 days to complete everything. I'm sure a pro could do it much faster. Have towed the 4" lifted (and loaded) Jeep accross the Rockies about 6 times and everything is working perfectly!! Very happy camper!! 301003

The product is a good quality I installed this before. This time I needed 4-5 feet extra wire to route it properly. That's why I give it a 4 start. On the end its worked fine. 252634

The wiring kit included all the parts listed and the video was most helpful with the installation. The installation went fairly easy until I got to the portion of running the brown wire from one taillight to the other taillight. The brown wire was not long enough. I had to splice another piece of wire on to the brown wire to make it longer. etrailer should consider making the length of included wire approximately 3 feet longer. That would have helped a lot with the installation. Also include a longer piece of the split protective plastic. Other than those two issues, I am satisfied with the product. 459131

Towbar wiring system arrived within 4 days of placing my order. This 7 to 6 wire system is an upgrade to the simpler 4 wire plugs I've used in the past and will allow me to add on a battery charge line or brake system later on. The demonstration video was indispensable in hooking up the wiring and diodes. Though running and connecting the wiring does take longer than a 10 minute video. Now I can tow my 2016 Jeep Wrangler behind my RV. 444983

We have towed our Jeep almost 2,000 miles since installing the recommended parts from etrailer and it has worked perfectly on every connect and disconnect along the way. Tows beautifully, even at 70 mph. Excellent customer service and helpful videos from these folks. Would recommend to anyone needing help with parts and guidance in towing their toad to give them a call. 616795

Excellent company. Great communication, fast shipping and the products worked perfectly. I had some trouble installing this to my rear brakes, but that was my own fault. I didn't realize that the brake lights are grounded when they are mounted to the Jeep. So I kept testing the lights once they were hooked up, however they weren't mounted back on the Jeep. It wasn't until everything was mounted back on that it all worked without any issues. 305606

I ordered an entire setup to flat tow my Subaru with my RV. Having never done this before I was nervous about missing something I might need. etrailer made it very easy when I called them on the phone. I told them what I was trying to do and they made sure I had everything needed to complete the job. I was given a name and phone number to call the same person if I had any issues. When one of the boxes was opened it was missing two pins from the manufacturer. A quick phone call and they had them in the mail in a matter of hours. This kind of personalized service is missing in our ever changing world. It was a pleasant surprise to find it here. Great Job etrailer. I will favorably recommend to everyone. 493275

This product is incomplete. 4 feet more wire and five wires instead of 4 wires. The 4 wires are at least 4 feet short requiring you to purchase more from a local hardware store. This kit also does not combine the brake and turn signal requiring an additional wire. DO NOT be fooled by this kit. If you have a supplemental brake They want you to buy another kit that is impossible to install on the brake switch under the dash. I just added two relays at each taillight to keep the motorhome brake power from mixing with the Explorer power. Very simple and everything is easy to access. 519554

Very good product. Was fairly easy to install if you are a little mechanically inclined. Take your time and think it thru and it is not that hard to install. The wire was the perfect length. 574014

I bought and installed base plate and wiring on a 2018 Ford C-Max hybrid car. The wiring was a little complicated due to the hybrid setup on the car, however, everything worked out well. I have done this on several other cars I have towed behind my motorhomes. All products and help from etrailer.com was excellent. The video presentation was very helpful. 681636

Everything needed to add tail light, turn signal and brake light's to your towed vehicle is included in this kit. The bracket for the 6pin connector is also included which is great. My main recommendation is that before splicing wires is to make sure your RV or towing vehicle wiring is as described in the documentation. I made my own table of 7pin wiring from the RV to the 6pin connector which is part of this kit. While all the documentation and was correct in an installation a few years back I wasn't as lucky and spent later many hours troubleshooting my connections only to find out that the RV was not wired the way the documentation stated. Again, do yourself good and check the RV wiring with a buddy so you know how it is connected. One other thing. Make sure the 27ft 4 wire cable is long enough for your application. With our truck it was on the short side and I had to splice some of the unused white wire. Lastly, and this is not part of this kit, but the provided 6pin connector has the provision for it, is if your RV has the 12V line and you intend to use this line to charge your towed vehicle, then make sure your umbilical cord carries that wire to your 6pin connector on your towed vehicle. Utilize that pin to bring 12V to your battery with an adequate breaker in place (I used 15A) with a diode to prevent the current going to the RV. 643832

Do you have a question about this Tow Bar Wiring?


  • Flat Towing Wiring Kit for a 2018 Jeep JL Wrangler Unlimited
  • The Tekonsha T-One # 118786 that you referenced is for activating the light functions on a trailer when towing with your 2018 Jeep JL Wrangler Unlimited. It sounds like you are needing some wiring to flat tow your Jeep and for that you need some different parts. If you use the Hy-Power Diode Wiring Kit # RM-152 along with the Hopkins Mounting Bracket # HM48605 and the Pollak Heavy-Duty, 4-Pole, Round Pin Socket # PK11410 then you will essentially have the Flexo-Coil Wiring Kit # RM-15267...

  • Parts Needed to Flat Tow 2018 Jeep JL Wrangler Unlimited
  • For your 2018 Jeep JL Wrangler, I recommend the Roadmaster EZ5 Base Plate Kit # RM-521450-5. This base plate kit is confirmed to fit your Jeep with the factory bumper and will work perfectly with your existing Falcon 2 Tow Bar. When installing the base plates, you will likely need to trim some fascia to allow enough room for the receivers (see attached pictures). I have attached the complete installation instructions that you can also look through. In order to flat tow your Jeep...

  • Flat Tow Wiring for a 2017 Jeep Wrangler
  • The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, part # RM-15267, is the best option for you to use to flat tow your 2017 Jeep Wrangler. It will provide a 6-Way wiring harness to the front of your Wrangler that you can connect to the 7-Way on your RV with the included Flexo-Coil cord. If your Wrangler has separate lighting you will need to use a wiring converter, part # 118158, along with 2 additional diodes, part # RM-792, to keep your turn and brake signals separate. If...

  • Wiring to Flat Tow a 2019 Jeep Wrangler Behind a Motorhome
  • Magnetic tow lights, like part # TL21RK, do their job just fine, are less expensive, and don't require much to setup so they're not a bad option by any means. The only real drawbacks to them is that you need to set them up or take them off each time you change from towing to driving the Jeep. They also have a chance of scratching the Jeep's paint since they're being attached to its surface each time. We often recommend them if you're not going to be towing the vehicle very often or if...

  • Recommended Toad Towing System for 2018 Jeep Wrangler JL

If you desire more security I also would add the Blue Ox Base-Plate and Receiver Lock Kit - Qty 4 # BX88177 which will give you the hitch pins for your motorhome hitch as well as a high-low adapter and then the pins for your base plate connections. Then for your tow bar wiring I recommend the Roadmaster Diode...
