Video Transcript for Demco SBS Towed Vehicle Battery Charge Wire Kit Installation - 2021 Jeep Gladiator

Hey, everyone, Shane here with etrailer.com. Today I have a 2021 Jeep Gladiator, I'm going to walk you through how to install a charge line kit for Demco's supplemental breaking system. The charge line kit is not a part that is necessary when flat towing a vehicle. However, I always recommend it because your braking system is tied to the battery, if your vehicle is shut off you have no way of charging your battery, but the braking system when it activates the brakes or applies the brakes, it's pulling some power from the battery. With the charge line kit, it's going to run from the battery up to the six pole plug on the front of the vehicle so that when you're running the motor home and it's attached to the vehicle, the alternator on the motor home is going to trickle charge your battery while it's being towed. So as the power is being pulled from the braking system, or pulling the power from the battery to activate the braking system, the motor home is charging the battery that way when you get to wherever you're going, your battery is going to be charged and ready to go.

You don't have to rely on somebody else to jump-start you, you're not going to be surprised when you get there. You don't have to go and try and find jumper cables 'cause it can be a little bit embarrassing. As far as the installation process, it's very simple, a single red wire, one end is going to have a fuse holder with a ring terminal, the other end is going to be bare which connects to six pole plug on the front of the vehicle. To start your installation, we're going to take the fuse in the ring terminal side, and we're going to lay it up by the battery. We're going to take the bare end and we're going to route it down to the front of the vehicle.

How I routed it was behind these cables, factory lines, behind our breather box, right down behind the front grill, across the back, you want to make sure you're staying away from anything hot or moving once you get down there, go over the frame rail, get them across, and then right here on our six pole plug, you're simply going to take that wire and you're going to put it on the center pin, or the auxiliary pin. Now, when you make this connection, don't have it connected to the battery and don't have the fuse in the holder. Once you make this connection, make sure the fuse isn't in the holder, connect the ring terminal to the battery, and then insert the fuse, other than that, that's all there is to it. So now what we're going to do is run a test and make sure we're getting power through our wire. Now, we won't be able to test it at six pole plug because with the Demco charge line kit, it's going to have a diode in there, and what the diode does is it only allows power to come from the motor home to the battery.

It's not going to allow any backfeed from the battery or from the line to the motor home, so if the vehicle is still connected and when the vehicles are shut off, it's not going to drain the power on the motor home, or the battery on the motor home. So what we'll do is we have our fuse inserted. That's telling us we have power in our line connected the positive side of the battery. That's going to do it for look the at and installation on the charge line kit for Demco's supplemental breaking system on a 2021 Jeep Gladiator..

Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems - DM66VR

Average Customer Rating:  4.9 out of 5 stars   (44 Customer Reviews)

Maintain the battery charge on your towed vehicle while it is being flat towed with this charge wire. Works with Demco supplemental braking systems.

by:

Really good tow bar. It has pulled my Jeep Cherokee for over 7,000 miles this year with no issues. Only problem was when I had to do a u-turn with minimal turning room and one of the storage pins on top of the tow bar got bent.




by:

I received my battery charge wire kit and installed it in less than 30 minutes. I installed it after a 2 day trip towing my Jeep and found that the battery was dead. That was due to the installer not recommending it. I now have peace of mind. The price for the kit is great considering that looking around most were considerably more.




by:

This did the job of what it was supposed to do after a different version of a towed vehicle charger didn't work at all. We had only ever towed a car for less than 3 hours or so. Imagine my surprise when the first time we towed further than that, we arrived to our site with a dead battery. I was able to determine that the other version didn't have continuity (in either direction) across the fuse. Installing this one kept the vehicle's battery fully charged...it worked like it should. The only reason for not giving 5 stars is that it seems a bit expensive for a fuse holder and a diode....but maybe that's what an actual functional diode costs.




by:

Works as described. A little expensive for a little wire, diode and connectors. However, easy to install and keeps my toad battery charged.




by:

This item serves a purpose that normally is not noticed, it keeps your towed vehicle's battery charged while being towed. It is a very acceptable small price to pay for the certainty that you will have a good charge in your towed vehicle. And it is not difficult to install.




by:

I assume it works like intended. I pull for up to 10 hrs in a day and have never had a battery issue.




by:

2013 Jeep Wrangler. Kit had everything i needed and wire was long enough. Easy installation.

Still going strong

Works great after the first year. Initially, I wasn’t going to install a battery charge line, but with my built in braking system and driving from Michigan to Alabama, I decided to do it. Glad that I spent the time up front to install it. Having a charged battery upon arrival and having the battery properly powering my dingy tow Jeep braking system is one less thing to worry about when I RV.




by:

Works great at keeping our towed vehicle battery charged.




by:

Super easy to install and did the trick. Glad I purchased this for my Jeep.




by:

Timely delivery. Works perfectly!




by:

Got it today just what I needed. Thanks for the good service.




by:

Perfect solution. Thanks.




by:

Works as designed.




by:

Product looks like it should work. Haven’t tested it. But $20 for a wire diode and a fuse seems expensive.

  • Does Demco Towed Vehicle Battery Charge Kit part # DM66VR Fit Only Demco Towing Setups
    You could use the Demco Towed Vehicle Battery Charge Kit part # DM66VR on your 2013 Jeep Wrangler regardless of what flat towing setup you have since it's design is universal.

  • Towed Vehicle Battery Charge Wire Kit
    Yes, you should be able to set up your Jeep Gladiator same/similar as Wrangler. Are you using the same supplemental braking system you had on previous towed Jeep? Was your previous Wrangler set up with something such as the Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems, # DM66VR?

  • Is There Voltage Drop Through the Diode of the Towed Vehicle Battery Charge Wire Kit DM66VR
    There isn't a significant voltage drop through the diode of the Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems # DM66VR that you referenced. The fuse and diode of this kit is rated for 10 amps so as long as the circuit stays under that it would work great.

  • Rating of Inline Diode on Demco DM66VR Towed Vehicle Charge Line Kit
    I spoke with my contacts in the tech services department at Demco, and was told that the inline diode used on the # DM66VR charge line kit has the same rating as the inline fuse, which is 10 amps. The diode acts as a check valve which only allows 12V power to travel from the motorhome to the towed vehicle, and will prevent backfeeding.

  • What Gauge Wire Is The Demco Battery Charge Wire Kit
    The Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems # DM66VR uses a 14 gauge wiring. The ground wiring should be 12 or 14 gauge. I attached a review video link below.

  • Will The Demco Battery Charge Kit # DM66VR Maintain Battery Voltage Without Overcharging?
    Yes, you can use the Towed Vehicle Battery Charge Wire Kit # DM66VR on your 2014 Honda CR-V. This will protect your battery from becoming damaged as it will connect to the charging circuit on your motorhome. It has a 10 amp fuse and diode that ensures it won't back feed into the motorhome as well. And it will not overcharge the battery as the charging system on your motorhome will only allow the same voltage that your battery gets from your alternator on your CR-V. Since your Demco Air...

  • Will Demco Stay-IN-Play DUO w/ Coachlink Monitor Braking System on 2021 Jeep Wrangler Unlimited
    Good questions, and the answer is yes, the Stay-N-Play DUO with the Coachlink will allow you to monitor the brakes on your 2021 Jeep Wrangler Unlimited as it is being flat towed, and you'll also need a brake light switch. As far as the best one, there is a switch from Roadmaster which is designed specifically for your Jeep, so here is exactly what you'll need: - Demco Stay-IN-Play DUO Supplemental Braking System with Wireless Coachlink Monitor # DM86VR - Roadmaster Stop Light Switch Kit...

  • How Does the Demco SBS Stay-IN-Play DUO Supplemental Braking System Get Power
    The Demco SBS Stay-IN-Play DUO Supplemental Braking System part # SM99251 will pull power directly from the towed vehicles battery therefore the Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems part # DM66VR is recommended.

  • Which Pin of Roadmaster 7-Way to 6-Way Diode Tow Bar Wiring Kit is 12 Volt Power
    The 6-way that is on the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 has it's center pin as the 12 volt power circuit. So when wiring up the 6-way female connector on your vehicle to charge it's battery you'd use the center pin for the # DM66VR and you'd be set.

  • Is Demco Charge Line Good Idea with Blue Ox Patriot on 2021 Jeep Wrangler
    Yeah it would be a smart idea to run the Demco Charge Line part # DM66VR to your 2021 Jeep Wrangler that is using the Blue Ox Patriot # BLU37TR that you mentioned as the Patriot will use the vehicle battery when towing but the charge line will keep it topped off. I attached an install video for the # DM66VR on a similar Jeep Gladiator for you to check out as well.

  • Parts Needed to Flat Tow a 2021 Jeep Cherokee
    For your 2021 Jeep Cherokee you will at minimum need base plates, a tow bar, safety cables, a wiring solution to display your indicator lights from the RV to the Jeep, and a braking solution/supplemental braking for the Jeep. I recommend the Demco Tabless Base Plate Kit, # DM9519307 that will match perfectly with the Demco Dominator Non-Binding Tow Bar, # DM9511008 you have been looking at. This also includes the needed safety cables. For the wiring, I suggest the Demco 4-Diode Universal...

  • Can 6-Way Be Added to Blue Ox Tow Bar Wiring Kit for Jeep Wrangler
    Yes, you can cut off the 4-way that comes on the Blue Ox Tow Bar Wiring Kit part # BLU79FR and use the connector from the Blue Ox 7-Wire to 6-Wire, Coiled Electrical Cord part # BX88206. If you need a charge line I like the Towed Vehicle Battery Charge Wire Kit part # DM66VR.
