Video Transcript for Review of Demco Tow Bar Braking Systems Parts - Second Vehicle Kit - SM6270

Hey everyone. I'm Ellen here at etrailer.com, and today we're taking a look at the re-install kit for your Stay-N-Play duo supplemental braking system. So if you happen to be changing to a different vehicle to tow with, or maybe you're getting an additional vehicle for your Armada while you're out on the road, you want to have multiple vehicles to tow with, but you still want to be able to utilize your Stay-N-Play system, this is going to be the kit for you. It's going to give you all the pieces that would have been consumed in the install for your first one, or that might be worn, so you want to have a new fresh one for your new vehicle, like your breakaway switch that is going to come with the kit. This is going to be that component that brings our vehicle to a stop in the event of an accidental disconnect. It'd pull that cable, pull out the plunger and apply the brakes in our towed.

The wiring coming off the back there will also have our indicator light. That mounts to the back of your rear view mirror, or somewhere on your dash so that you can have a visible indicator that the brakes are being applied in your towed vehicle. We also have a length of quarter inch air tubing. That goes from your control box to your actuator.We'll also have some new clamps, the check valve T, and unions for our vacuum line. There should have been a lot of vacuum line in your original kit, so hopefully you still have that to work with, and be able to connect into your new brakes on the new vacuum line on your new vehicle because this does not come with any vacuum line.

It is sold separately as a replacement part if you do happen to need some, or you can also fix them up at your local hardware store. But again in that original camp they usually provide you with more than enough vacuum hose to get that whole thing installed.We'll also get some ground wires and just lines of white wire, a fuse holder with 20 amp fuse, some ring terminals, butt connectors, that little T, or tri-butt connector. These are going to be two single diodes; they include these in case your braking, or your wiring isn't protected by a diode, so that would be your tow bar wiring. Most kits these days are going to have a diode already in place. We always suggest you get a diode system for that tow bar wiring, but if you happen to have a situation where there is no diode, these are diodes to put in that connection.

There are instructions on how to do that in your original kit. So, like I said, it's more than likely your vehicle will already have the diode wiring. If you have the tow bar wiring kit. A lot of those are available here at etrailer.com so definitely check them out if you don't already have it for your vehicle.Some zip ties here we can tidy it up, and some quick splice connectors. We'll also have two self-tapping screws to bolt down this little bracket.

This is for your cable anchor coming off of your brake actuator. So it provides a more stable point to mount that if the firewalls too thin, or if you have kind of a funky angle, it can help to make that a little bit easier, and you will need to use that self-tapping screw to anchor that down from the original. This hardware is going to be for our breakaway switch, so hopefully that kind of recovers everything here on what it is and where it's going to go. So the things that you'll need to reuse from your original kit will be the actuator, the control unit, the G-Force unit, and any indicator that you might've had in your RV.So that's pretty much all you'll need to transfer from one to the other. You'll also need the cable going between your safety chain loops and the front of your breakaway switch, and also the wiring connection from your towed vehicle to your RV. That's usually sold separately anyway. So, all those things are what will be reusable for this kit. Again, this comes with everything you see laid on the table. The part number that this works with is going to be SM99251. The Stay-N-Play duo system. This is made in the U.S.A. That's going to do it for this video. I hope this has been helpful in deciding if it's going to be the right kit for you. If not, let us know, and we'll hopefully answer any questions that you might have. Thanks for watching.

Excellent product and customer service, the last kit was purchased close to 35 years ago when we first began flat towing. Was still working fine. The reason for purchasing the new reinstall kit was to set up my new Jeep Wrangler.

All the components were included making it a breeze to reinstall braking system in my Colorado pickup

  • Recommended Flat Tow Setup for a 2014 Chevy Captiva Sport
    I can definitely help you out with parts to flat tow your 2014 Chevy Captiva Sport. I really like the Demco setup you were looking at because Demco offers a few kits that include just about everything that you need, plus they have very nice tow bars that will last you a long time which you can use on future vehicles you choose to flat tow. For a base plate kit use part # DM9518218 and the the Demco tow bar I recommend is the Dominator # DM9511008 because it has a 7,500 lb weight capacity...

  • Parts Needed to Flat Tow 2009 Honda Fit
    Since you have the SMI DUO # SM99251 currently all you need to install it in your 2009 Honda Fit is the part # SM6270 and you'd be set. For a base plate kit the Blue Ox part # BX2253 would be what you'd want with the Avail tow bar part # BX7420. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle....
