Today on our 2013 Jeep Grand Cherokee we'll be installing the Roadmaster 12V Outlet Kit, part number RM-9332. Our 12V kit will ultimately get installed and secured to the battery. For this application, the battery is located under the passenger seat. If we lift up on the battery cover to get to the back half of the battery, we're going to go ahead and move the seat all the way forward and towards the dash. Release the cover and set it aside. You can see we've now exposed the battery. We're going to go ahead and open up the console, the lower portion of our console here. We can remove the rubber liner.
Next, on the passenger side front corner, we're going to drill a hole in the bottom of the console, just large enough that we can fit our wire and fuse holder through. Once we know that our fuse holder will fit through the hole, we know the rest of our wire will, and we can feed it down along the bottom edge of the console. Next I'm going to pull out on the bottom of the console, where it meets the carpeting. Locate the wire and pull it out. Now if you're unable to get it to feed out the bottom easily, what we can do is pop the console free here and locate the fastener that holds this side panel of the console. Were going to go ahead and remove this fastener and pop the side console free. Now with the top fastener out, I'm going to go ahead and pop the side-access panel free; we remove the bolt that's holding the panel in place.
Once we pull our wire out, we'll go ahead and route it underneath the carpeting, here we're it splits in the middle of the seat. Then we can route it into the battery tray. Now once we have our wire in place, we'll go ahead and put our console back together. Now our power supply would generally come from a fuse port and we'd use the fuse tap supplied with the install kit. However, since we're going directly to the battery, what we're going to do is just add a short piece of power wire that will fit directly into the other end of our fuse holder. Once we fit it in place, we'll crimp it down. The other end of our piece of wire, we're going to add a ring terminal that will fit over the positive battery post; crimp it down to secure it.
We can then go ahead and put the cap back on the inline fuse holder. We'll run the inline fuse holder to the power side; the other side is our ground wire to the negative battery post. Now to secure our ring terminals to the post, we're going to add 2 6-mm nuts. These nuts will allow us to put the ring terminal onto the post and secure the nut, holding the ring terminal in place. Let's go ahead and do the power side first. We'll put the ring terminal over the positive battery post and then install the nut.
Now with the ring terminal secured to the positive battery post, I'll move over here to the negative battery post and repeat the same process. With that secured, we can now go ahead and reinstall the battery cover. Now with our console trim panels back together, we need to put the bottom liner back in, which will cover up the hole we drilled in the bottom. With that, it now completes our direct battery feed 12v power supply. On applications where your vehicle is in tow mode, because it's being towed recreationally, you have a direct feed to the battery such as for reasons for using a braking system. There you have it for the install of our Roadmaster 12V Outlet Kit, part number RM-9332 on our 2013 Jeep Grand Cherokee. .

Ratings & Reviews
I'm installing this currently. It is very well made and installation is quite simple. This is a dash install for me as I'm using this to power my Furion monitor that sits on my dash.
They installed a bull oz towing system and it is fantastic. It was installed in a brand new Buick and would never know they did a thing. Everything is well installed and out of sight. Would use them to install anything on my cars
fairly easy install when you follow the video's
Works great
This 12 volt wiring kit was easy to install. I use it to provide power to my Roadmaster 9400 Even Brake supplemental braking system in a 2017 Chevrolet Equinox. It is quality product. The Video by etrailer.com provided a helpful addition to the instruction supplied with the kit.

Still performing great. Easy installation. I recommend this kit.
I watched the installation video before purchasing this Outlet Kit. My installation of it was into a 2010 Subaru Forester and was no different than the video. It went without any difficulty.
The only weak point to the kit in my opinion is the brass connection piece that attaches to the fuse. It fit over the fuse connection fin without any problem.
The shortfall comes when one connects the female positive connector to the exposed part of the brass connector. The positive connector is much wider than the brass connector which goes on the fuse, making the connection loose. I crimped the positive connector in order to keep it attached to the brass connector.
I ran the outlet wire under the door sill, in the wire trough there so the outlet would be in the rear seat area. I use the outlet to power my 12VDC car refrigerator.

It performs perfectly. I am extremely satisfied with the product.
Provided valuable consultation on device needed to resolve my needs.
Great device. Gives that much needed HOT accessory socket inside the car for the braking system and when not towing, other accessories that you want to dtay connected to the battery when the ignition is switched off. (inverter for a laptop or tablet charger for instance or even a small TV.) Could be a little less expensive but it IS a higher amperage socket than you can find at the local car parts store. Quick and easy install. Recommend wire loom around the wires to protect them from wear in the engine compartment

Awesome. Great power source for cell phone charging or an inverter for powering a laptop
Good instructions and easy to instal tnx to Lori AB for putting my order together
Working great
easy to set up and works great
Needed for towing for the lights and have had no issues at all using this for the last year
Pretty simple . Keeps battery charged.
lighter cylinder doesn't fit bracket. I bought this as a kit if it does't fit its not & should not be sold as a kit. Spent an hour filing bracket to fit cylinder. Not happy.
I had it professionally installed. It appears to be functioning fine. Our first trip is coming up Friday so I’ll give it a true test.
Worked great until it totaled the car. Installation was fairly simple. We used it for 5000 miles with no problems to power our Blue Ox brake.
Everything looks good thanks for your h elp.
Great videos to assist with installatio n.
Wrong fittings for battery hookup.
work perfect with my Blu Ox breaking sy stem
I ordered the item from Kelly P online; she was great then. I paid an additional fee to have the order delivered in 2-days. The shipment never arrived. I tried calling and emailing her but she wouldn’t reply. Fortunately i called the customer service line and was refunded the item and cost of the additional shipping.
I ran this to the hot wire coming out of the 7 wire plug for the coach, I had to add wire to reach the front of the car. It has power any time I’m hooked up to the coach, I use it for my portable blue ox braking system.
I would give it a 5 star, but had to alter the bracket so the outlet would fit it. Other than that it works great. I would suggest the bracket be redesigned so your customers dont have to alter items to make them fit.
Received the 12-volt outlet kit in quick time. It is a high-quality piece which is what I like to use. Need to do the installation next and I see no problems as I will do a direct to battery install. And the kit comes with plenty of wire to reach the battery.
The bracket that holds the receptacle is too loose. When inserting a plug into the receptacle it can/will pop out. Tried crimping it down, a little better. It’s under the dash and so a little electrical tape never hurt anyone.
Connecting to my Maverick via the default fuse method not an option. Iplanned to attach to the jump post anyways. Clip off the fuse tap and…the supplied ring terminal was tiny. Adding a few different sizes of ring terminals would be appreciated and increase build cost about 15¢.
Do you have a question about this 12V Power Accessory?
