  • Disconnecting Battery in 2015 Chevy Colorado When Flat Towing
  • The main reason that the battery must be disconnected when flat towing is to prevent the battery from draining. When flat towing your 2015 Chevy Colorado, the key must be left in the (II) position. This would leave some of the electrical components on and drain the battery. To eliminate the hassle of having to disconnect your battery each time you want to flat tow, I recommend installing the Roadmaster Automatic Battery Disconnect, part # RM-766. The automatic battery disconnect is activated...

  • Do You Need a Fuse for the 41-1/2" MaxxTow Off-Road Light Bar
  • The MaxxTow Off-Road Light Bar part # MT80634 comes with a wiring harness that has a built-in relay so you don't need to worry about any additional fuses or breakers, just hook the pre-attached ring terminals to the battery. That said, the light bar will pull around 20 amps at full power.

  • Installing Brake Controller in 2001 Monaco Dynasty
  • Yes, the answer page I wrote for installing a brake controller in a 2008 Monaco will be exact same as your 2001 Dynasty: The blue wire goes to the brake output circuit of the 7-way on your motorhome, the white wire goes to the ground of your battery, the black wire will run to the positive post of your MH battery through a 20 amp circuit breaker like part # PK54220, and the red wire goes to the cold side of your stop light switch on the brake pedal, in your case it should be the wire number...

  • Could Single Park Light Diode #RM-690 Be Used On Other Taillight Circuits Besides Running Lights
  • You would be able to install the Diode part # RM-690 on any circuit you wanted to protect. We have some people who use them to prevent backfeeding while charging the battery or for TrailerMate wiring kits we have found that you do need to install a diode on all three circuits if using an Invisibrake. You are also correct that installing these on the motorhome side of the wiring would allow you to only have to install the diodes once and not on every single vehicle you flat tow.

  • How to Find Cold Side of Stop Light Switch for Brake Controller Installation
  • I can tell you exactly how to find the cold side of the stop light switch that will attach the red wire of your brake controller, though as of this writing (May 2019) we have not yet had a chance to wire a controller to a 2019 Jeep Wrangler. What you need to to is locate the wires connected to to the brake switch at the top of your brake pedal. Then use Circuit Tester # PTW2979 and find the wire that is active only when you press on the brake pedal; that will be the wire you will splice...

  • Is A Battery Disconnect Needed for a 2015 Jeep Wrangler To Prevent Dead Battery
  • There isn't a battery disconnect required for the 2015 Jeep Wrangler. If it was required, it would state this in the owner's manual. In regards to the key position this would be listed in the flat-tow setup procedure for your vehicle which is in the owner's manual. I would not have any additional information outside of this. That said, the battery going dead is an easy fix as all you need to do is install a charge line between the motorhome and toad using the Roadmaster Battery Charge Line...

  • The Roadmaster Adapter for Jeep D-Ring Bumper Mounts # RM-035 will install on the ends of your Roadmaster Falcon 2 Tow Bar # RM-520 arms in place of the existing black quick-disconnects.

  • Which Setting for Brake Buddy Classic 3 When Used in 2017 Jeep Wrangler
  • I was able to confirm with my contact over at Hopkins, who manufacture the Brake Buddy Classic 3 # HM39494 that you will want to use the standard setting with your 2017 Jeep Wrangler. You would only want to use the "hybrid" setting with an actual hybrid vehicle since the amount of brake pressure required in those braking systems is minimal compared to regular vehicles, even with assisted braking systems. I've linked an installation video of this system on a similar Jeep JK for you to...

  • How Does The Hopkins Custom Tail Light Wiring Kit Get Installed On A 2017 Jeep Wrangler?
  • To install the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 on your 2017 Jeep Wrangler, you'll plug the female end of the harness into the existing male connector from your taillight, and then the other male end of # HM56200 will get plugged into the taillight. So since you have a 4-way that uses the same plug, then it does not matter which one goes first or second. I have included an installation video on a 2018 Jeep Wrangler for you to check out as well.

  • Do I Need a Hitch Extender with the Kuat Transfer V2 on My 2021 Jeep Wrangler with Spare Tire?
  • There is definitely a way to find out! Since the Kuat Transfer V2 # KU84FR has a 6-1/2" length from the center of the shank's pinhole to the closest part of the rack, I recommend making a measurement on your 2021 Jeep Wrangler. You need to measure the center of the hitch's pinhole to the outside surface of your spare tire. If that length is less than 6-1/2", you do not need a hitch extender. I went ahead and attached a photo that shows how to do this measurement. If you find that you need...

  • What Is The Needed PSI For Roadmaster InvisiBrake Supplemental Braking System & Jeep Wrangler
  • The Roadmaster InvisiBrake Supplemental Braking System, # RM-8700 has been pre-set at the factory at a level appropriate for "most" towed vehicles; there may be no adjustment necessary but this must be evaluated. The correct pressure is dependent upon whether the brake pedal clamp is positioned as low as possible on the brake pedal arm; and the number of curves in the cable between the cable anchor bracket and the air cylinder. The higher the clamp is positioned on the brake pedal arm,...
