  • Is a Battery Charger Needed with the Stay-in Play Duo Supplemental Braking System?
  • On your 2018 Jeep Wrangler, I am thrilled with the parts you ordered. The Mighty Cord Trailer Connector Adapter - 4-Way Flat to 6-Way Round - 12" Harness # A10-6034VP will give you the 12V charge line from your 7-way on your motorhome to give a maintenance charge to your Jeep battery. Although a charge line isn't required, the SMI Stay-IN-Play DUO Supplemental Braking System # SM99251 does use that vehicle battery, so I do recommend connecting it. You can simply connect the 12V wire...

  • Supplemental Braking System Recommendation to Flat Tow a 2012 Fiat 500 Behind an RV
  • In the world of supplemental braking systems the discontinued AutoStop BX8893 is one of the more difficult installations. While it seems like a simple set up the reality is that routing the cable to the brake pedal can be complicated. Also if the breakaway system is used BRK3050 and gets tripped the system has to be sent back to the manufacturer to reset it. In short I would advise against this system and go with a less complicated braking system. One of the preferred systems for our...

  • Should SMI Stay-IN-Play DUO # SM99251 be Replaced with SMI Air Force One # SM99243 for New RV
  • Both the SMI Stay-IN-Play DUO # SM99251 and the SMI Air Force One # SM99243 are great supplemental braking systems that are very popular and have received many 5 star reviews from our customers. The only real difference between these systems is that the Stay-IN-Play DUO is activated by electrical and inertia sensors whereas the Air Force One is activated solely by the air braking system on your RV. The DUO will work on you deisel with air brakes but you'll likely experience false...

  • Wiring Instructions for SMI Stay-IN-Play DUO on 2008 Jeep Liberty
  • The SMI Stay-IN-Play DUO Supplemental Braking System # SM99251 referenced in your question does not require separate brake and turn signals to operate properly. However, if you want to use the separate turn signals on your 2008 Jeep Liberty, then I recommend installing the Roadmaster 6-Diode Universal Wiring Kit # 154-792-118158 to connect the Jeep's lighting system to your RV's. To let the Jeep's system operate the brake lights, the red wire coming from the converter on this wiring kit...

  • Recommended Permanently Installed Supplemental Braking System to Flat Tow a 2018 Ford Focus
  • On your 2018 Ford Focus I recommend the Stay-IN-Play DUO, part # SM99251, for a supplemental braking system. Mainly because no only does it work well (as does the InvisiBrake) it's a little easier to install. Our installers prefer it to any other permanently installed system. I've linked a video of when we installed it into a 2015 Focus for you. You're also going to need a Brake-Lite Relay, part # RM-88400, to keep the lights of the Focus from overriding the lights of the RV. The...

  • Parts Needed to Move SMI Air Force One to a 2018 Jeep JL Wrangler Unlimited
  • In addition to the Replacement Towed Vehicle Installation Kit # SM99226 you will also need brake light relay # RM-88400. The # RM-88400 relay is required to prevent the towed vehicle's brake signal from overriding the turn signal from the RV when applying the brakes during a turn but is not required if using magnetic tow lights such as # C-ATL20A. I have linked a video on the relay for you but it is on a JK model so it won't be exactly the same on your new 2018 Jeep JL Wrangler Unlimited....

  • Recommendations for Flat Towing a 2017 Jeep Wrangler with a Barricade HD Bumper
  • From the research I did online it looks like your Smittybilt tow bar is compatible with the D-Rings on your 2017 Jeep Wrangler Sport with the Barricade HD Bumper. If your Smittybilt tow bar is not compatible with the D-Rings then you can use the Roadmaster D-Ring Adapter # RM-035 for Off-Road bumper - with 3/4 inch D-Ring bumper mounts or D-Ring Adapter # RM-035-1 for Off-Road bumper - with 1 inch D-Ring bumper mounts along with a Roadmaster Tow Bar like the Falcon All Terrain # RM-522...

  • Does SMI Delta Force Portable Supplemental Braking System Apply Brakes Use Vehicle's Vaccum Assist
  • The SMI Delta Force # SM99242 does not use vacuum pressure like the SMI Stay-IN-Play DUO # SM99251. The Stay-IN-Play DUO ties into your vehicle's vacuum line and uses it to assist in braking. Since the Delta Force does not it applies more pressure to the pedal (As do many other braking systems) to get the same amount of braking force necessary to slow the vehicle.

  • Can SMI Stay-IN-Play DUO SM99251 be Installed in Engine Compartment in 2016 Jeep Wrangler Unlimited
  • There isn't a specific place that the SMI Stay-IN-Play DUO # SM99251 has to be installed on a 2016 Jeep Wrangler Unlimited. Under the seat is the easiest place to install it but if there is something in the way such as an under seat storage box then it can be installed elsewhere. If you wanted to install it in the engine compartment and there is space then you can certainly put it there. Also the # RM-88400 relay is required to prevent the towed vehicle's brake signal from overriding...

  • Replacement Air Jumper Quick Disconnect for SMI Air Force One Supplemental Braking System
  • Actually, you need the Replacement Female Quick Disconnect for SMI Air Force One # SM99613. Installation is fairly straightforward, especially if the base is still intact enough to reuse and you only need to quick-disconnect end. If any of the rest of the line is damaged and you need the entire line the part is # SM99666. It appears the line going into the male end (part # SM99614) is kinked.

  • Best Supplemental Braking System for a 1984 Jeep CJ-7
  • The best supplemental braking system for your 1984 Jeep CJ-7 is going to be the SMI Stay-IN-Play DUO Supplemental Braking System part # SM99251. The Stay-IN-Play DUO is a proportional system which means it will activate the brakes in your toad at the same time and with the same intensity as those in your motor home. The SMI brand has been around for quite awhile and they have fine tuned the Stay-IN-Play DUO over the years to be one of the best, if not the best supplemental braking systems...

  • It is recommended to install the Stop Light Switch Kit # RM-751439 on your 2017 Chevrolet Equinox to ensure that the LED notification works properly for the SMI Stay-IN-Play DUO # SM99251. If you can find a wire that is solely dedicated to the brake light then you can use the method that comes in the instructions for the DUO but we have found that it is difficult to locate this wire. You will need to remove some fuses to flat tow your Equinox as well. I recommend installing a Roadmaster...
