Hi there Coachmen owners, today in your 2020 Coachmen Mirada Select, we're going to be taking a look at and showing you how to install Roadmaster's charge line kit. This 12 volt charge line kit is going to provide you with the necessary wiring to have a charge line on your seven way connector. Your standard seven way is already going to have this here, but many of your motor homes don't come with a fully operational seven way connector. This is just the one circuit for the charge line circuit, which is necessary on some of your braking systems and also necessary if you want to charge the battery on your vehicle when you're flat towing it down the road. If you're going to haul any trailers with you as well, and you have batteries on those trailers, you'll want a charge line on there, especially if they have brakes. That'll keep the battery topped up on the trailer in the event that you do have a breakaway situation, that battery can be fully charged to apply the brakes.Our Mirada here didn't come from the factory with a fully functional seven way, so we had to add that additional wire for our Brake Buddy stealth braking system to work on our flat tow setup here.
It's an extremely straightforward installation, you're just running a wire from your battery back here. There's a circuit breaker that comes included with the kit to ensure that the wire remains circuit protected. But other than that, that is basically it. Follow along with me and we'll show you how to get her hooked up.We'll begin our installation by locating our batteries. They can be found underneath the steps, when you go to walk in your motor home.
We just lift up on the compartment door here and we've got our batteries here. Next we're going to want to mount our circuit breakers close to them as possible. So we just put it here on the back wall and use the included self-tapping screws to run it in. And you can use an eight millimeter socket with those self tapping screws. We then have two wires we need to run.
One is going to run right to the battery here. I recommend you wait to install this one until after you run the other one so that way the wire isn't live. You'll notice you'll have three different ring terminals here. These two on the circuit breaker are going to be the ones that have the smaller hole. The larger hole one is for the battery side.We're going to crimp on the small ones, so we can go ahead and connect them to the circuit breaker.
Just hold off on the battery side. And then the main portion of wire's what you're going to want to start with with this one so you know you've got enough length, so connect the ring terminal to it, attach it, and then begin running it towards the back towards your seven way connector. We just follow it right down the frame rail, zip tying it to any factory wiring on the way, because we know the factory wiring is already routed in a way where it's not going to get damaged, come close to anything excessively hot or any moving components.So we just follow this wire loom out and follow it all the way to the back to our seven way connector. This is going to hook to your charge line pin. Now the connector that was on our vehicle originally didn't have a charge line pin in it whatsoever, so we did have to replace the whole harness here that goes through the seven way connector in order to have all the pins that we need. On the connector we replaced it with, we used one here from Curt, and the black wire coming off of this connector is going to be your charge line wire. So you can see right here, we took the red wire that we had routed back from our circuit breaker, we used a heat shrink butt connector and crimped it onto the black wire. Just strip back your ends, crimp on your butt connector, and then use your heat gun to shrink it down.Now, if you are replacing this connector here with one from Curt, it's pretty straightforward. I highly recommend what you do is replace it one wire at a time because the wire colors are not likely going to match up with your motor home. Motor homes usually have their own proprietary wire color that just doesn't match up with our standard seven way. So all you would do then is just match up pin to pin. So if we're looking at this white wire here, this is the bottom pin here, so I would start with this bottom one, I would cut it, and then I would wire it to the wire on the connector for our new one that lines up in the same spot, and then just work my way around doing it one at a time to make sure that all the pins line up with the same holes once you've made your connections. And that completes our installation of Roadmaster's charge line kit on our 2020 Coachmen Mirada Select..

This charge line connects to the battery in your RV to allow up to 15 amps to be transferred to your towed vehicle's battery during towing. Requires RM-156-25 be installed in towed car.These were exactly what I needed. I changed tow vehicles to a Honda HRV (manual) and the only base plate available was the Roadmaster. These adapters took about 10 minutes to change my Blue Ox tow bar to accept the Roadmaster.
Works great and allows me to tow with vehicle stability turned on; no more death wobble! Installation instructions were clear and it fit perfectly.
This is also a part i ordered for my tow behind car in order to charge the battery while pulling the car with the A class motor home on a long trip. The item is just what was described on the internet site. I haven't installed this item yet but it seems to be easily done with the instructions provided. I have ordered from Etrailer many time before and have always recieved great help from customer service and their whole crew. I will continue to do business with them in the future.
Sincerely,
larry Brauer
Arrived early and installed easily however not enough protective sheathing provided to complete the job.
Roadmaster Battery Charge Line Kit for Motorhomes
Item # RM-156-75
Easy install, but suggest that the 12 gauge wire supplied was longer,or had a description as to the length on your website as it was too short for my 30ft MH. I had to purchase additional to complete the job. Otherwise, works like fine, and good price. Thanks, it should save my battery on my Equinox 2018 when towing.
Since I did not know exactly what I needed, customer service outlined the products and helped me select what I needed!
Nice kit as expected, Plenty of hardware and hook-up wire for our 2015 Dodge Dart. Would be nice to include $5 of snap on Red cover in the kit to help protect the hot leads.
This base plate was relatively easy to install (if you're handy and can follow written & video instructions), and is practically invisible when not being used for towing. Everyone at etrailer were helpful and knew exactly which parts were needed, even a year later when I asked about using the same base plate on a newer vehicle. The picture is just after install on my 2017 C-Max.
Work as advertised - no issues
Ordered 3 parts: RM-156-25; RM-156-75 and DW05745-10. All received very quickly, as is the case when I purchase from etrailer. More importantly, I get a 'live person' when I call for assistance and the service rep. is always knowledgable ( not an answering service that "will have someone call back". Time was spent with me answering all my questions and providing suggestions and opinions when I as for them, related to my project. Great company, great service - keep up the great work!
