Video Transcript for Roadmaster 12 Volt Outlet Kit Installation - 2016 Chevrolet Equinox

Today on our 2016 Chevrolet Equinox, we're going to be taking a look at and installing the Roadmaster 12 volt outlet kit for 20 amps, part number RM-9332. Here's what it looks like once it's installed. This will be a great additional outlet, should you need an outlet for a supplemental braking system that plugs into a 12 volt outlet or if you're going to put a spotlight, some kind of emergency light, or a cell phone. You can locate this anywhere this in your car you'd like, as long as it's on the inside of the vehicle and it's going to be good for up to a 20 amp drop. There's going to be a very simple install. You're going to have a ground wire and you're going to tap into a fuse that's hot on your vehicle at all times. This is going to give us constant power even when our battery's disconnected in tow mode so you want to make sure if you leave something plugged in there, it can run your battery low so keep an idea of what you've got to have plugged in there.

You don't want to run your battery dead. Let's go ahead and show you how to install it. Working on our outlet over here in the driver's side. We're just going to let it hang out the bottom so it can tie in through our supplemental braking system so they have 12 volts. We're going to take out this lower panel. I'm using a 7 millimeter socket.

It's going to be 2 screws. Just pull down, just set it aside. Now we have 1 more screw that's going to be this lower valance cover. There's a couple of clips we'll squeeze together and just push it down out of the way. That allow us access to get to where we're going to ground it, which is going to be on this factory grounding point.

Then we're going to run the other wire over into our fuse panel on the passenger side of our kick panel. In order to ground it over here, we're going to need to separate the 2 wires so we're just going to go ahead and pull them apart. The ground one we're going to leave on the side. For video purposes, I'm going to go ahead and remove this lower bolster panel here. Just so you can see exactly what we're doing. We're going to want our outlet to hang down in this area here.

We're going to take our power wire, that's going to be the one with the built in fuse holder. We're going to route it up the back side here. We're going to secure it to the backside here with some zip ties. We just want to keep this wire from dangling down to help keep it in place. Just make sure you keep it away from any of the sharp metal that goes in our dash, and we can turn off our excess. We're going to zip tie our plug to the wiring harness up here in the dash. We want to make sure we leave it just enough for it to hang out so we can use it. Then we'll trim off the excess there. I went ahead and took a piece of airline tubing using it as a fish wire, run it across the console, and we're going to feed across the side to our fuse box. I've gone ahead and loosened up our nut, I'm going to back it out. Our wire that came with it had a pretty good connector for a small wire, small screw. We're going to go a larger diameter ringwood connector that's going to fit over our factory stud. In the process, we can go ahead and shorten up our ground wire. Trim it back about a quarter inch. Slide it on the end. We'll inaudible 00:03:58 stud, being careful not to knock the wires that are already on there off and we'll reinstall the net. You want to make sure you keep this wire tucked up away from the mechanism for the emergency brake so it doesn't get tangled up. Then we'll just tighten this nut back down. You want to be careful in here because this is very sharp, the metal is. We can reassemble the lower part of our dash. We can place this back up into position. Now, it's got a bunch of snap tabs. We need to line those up first. We'll take our 7 millimeter head screws and we'll run them up. Now we can move over to the other side to tie it into our fuse panel. Then we're going to need to find a fuse that's hot with our key off. Right now our key is off so we're going to go ahead and use this 20 amp fuse right here in the middle. With our key off, I'm going to go ahead and remove this relay just so you can see what we're doing. You don't need to do that under normal circumstances. I'm going to take out this 20 inch fuse and we're going to put the supplied fuse cap. We're going to slide it on to one of the legs and we're going to pull it all the way down. You want to make sure it snaps around the back side of our fuse so it will sit in there flush. Now we want to test the socket that it came out of to find which side is hot all the time because one side is going to be hot all the time and one won't. We want to make sure we put the fuse tap to that side. Now with the fuse tap pointing towards the rear, we're going to reinstall our fuse. We'll double check. We have power. We'll take our inaudible 00:05:56 connector that's already on our new fuse holder. We're going to snap it into place and we'll bend it down, give us a little bit of excess. Now we can reinstall our relay and we can snap this cover back into place. We can test our outlet. Now our 12 volts is going to be at the very end where that rivet is so you want to make sure you've got a protected test light if you're going to deal with a test light, put it down the center. It's good. We've got 12 volts. That's going to do it for our look at and install of the Roadmaster 12 volt outlet kit for 20 amps, part number RM-9332 on our 2016 Chevrolet Equinox.

Great product Fast delivery and very easy to install. Great installation videos also, step by step 313359

I didn’t end up using it because I wired the brake controller directly to 12 V in the engine compartment. (I didn’t return it because I opened the package and threw it away before I realized I didn’t need it) 474490

I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great! 450643

The product works well with one exception. It could not be installed as shown because the wires were too short. A new place was selected for installation. It looks good and does what I ordered it to do 353134

Installation on a 2013 Fiat 500 Sport was a snap. Took no longer than 10 minutes. Works like charm to power auxiliary braking system when towing behind a motor-coach. Great service and delivery. Well written instructions. 73279



- RM-9332
by:

Works as advertised. The only issue I have is, even if you're not using it, it still drawing power 0.66volts which is too much draining my battery. 239777



- RM-9332
by:

Would work ok the way the video showed using it, wadded up under the dash. I wanted to use the supplied bracket but couldn't figure out any way it could hold the outlet. Nothing in the instructions about using the bracket. Bought a different one that had a usable bracket. 361456



- RM-9332
by:

Works great for what I need. I plug in my Patriot tow brakes and it needs a hot 12V connection. The power outlet in the car is only hot when the key is on. Mounted this in my Honda CR-V and it tucks up nicely above the fuel door release. The only reason I did not rate it 5 stars is that occasionally I have trouble getting it to make contact -- I believe it is with the Patriot unit rather than this, but I rated them both down a star not know I g which is the culprit. 367767

Except for bracket holder which did not work very well and was not explained very well on how to use it. The product itself worked well operating my add on electrical defroster 441590

Product worked well except for bracket holder when plugging in the socket would move. Had to add a hose clamp to keep it in a useable postion

The electrical socket outside diameter is much larger than the hole in the bracket. It does not fit, not even close. So the electrical socket can’t be mounted in the provided bracket. It is junk. 582177

Very impressed with item. It has everything you need to add a 12 volt outlet that is on continuously. The fuse tap was easy to apply. Took about 20 minutes to install. 547168



- RM-9332
by:

I suppose this would serve its purpose of providing power from the battery if I was going to use it. It is to be mounted inside the vehicle, but it doesn't come with a cap or cover for the socket when it is not in use so it won't be installed and used at all. 522118

Everything arrived very promptly. There were no problems with the order. I have not put everything together. It will not be installed until Monday, Nov. 27. However, etrailer.com made ordering everything very easy, to match all the correct parts with my truck and motorhome with all the correct matching parts, which was quite daunting for me. When it is all installed I will give you a full review. Mark 452646

I installed this item on a Honda CRV 2014 so I could install the Patriot brake system. Installing the 12vt plug was the easiest part with the good instructions from etrailer. Hooking the hot wire to the fuse was the trickiest part. The product has worked as advertised and I have had no problems with it. 379361

Ask the Experts about this Roadmaster 12V Power Accessories
Do you have a question about this 12V Power Accessory?


  • Does Blue Ox Patriot Braking System Drain Vehicle Battery
  • The Blue Ox Patriot part # BRK2016 will be powered by the vehicle battery it is installed in so over time if the vehicle wasn't started periodically the battery would run down. To prevent battery draining on a towed vehicle we typically recommend the battery disconnect part # RM-766. This will disconnect the towed vehicle's battery while being flat towed and will charge the battery as well. This taps into the running light circuit (brown wire) of the 4-way you have on your vehicle...

  • Difference Between Roadmaster EZ4 and EZ5 Base Plates for 2017 Jeep Wrangler Unlimited
  • Both the Roadmaster EZ4 Base Plate Kit # RM-521448-4 and EZ5 Base Plate Kit # RM-521448-5 will fit on your 2017 Jeep Wrangler Unlimited. The primary difference between the two designs is the way they attach to the tow bar. The EZ5 does not use the quick-connect crossbar which provides a cleaner look, but prevents you from using some accessories that mount to the crossbar such as a Rock Guard like the Roadmaster # RM-4000. If you are at all interested in using a rock guard or protective...

This base plate kit is confirmed to fit your Jeep with the factory bumper and will work perfectly with your existing Falcon 2 Tow Bar. When installing the base plates, you will likely need to trim some fascia to allow enough room for the receivers (see attached pictures). I have attached the complete installation instructions that you can also look through. In order to flat tow your Jeep...

  • How to Power Blue Ox Patriot II Braking System with Vehicle that Requires Battery Disconnected
  • There are several vehicles that require you to disconnect the vehicle battery when flat towing. The solution then to power a braking system like the Blue Ox Patriot II # BRK2019 is to use an outlet kit like the part # RM-9332. This wire directly to the vehicle battery so that you can get power for the system directly while still allowing the vehicle battery to be disconnected.
