Video Transcript for Roadmaster 12 Volt Outlet Kit Installation - 2018 Jeep JL Wrangler Unlimited

Today on our 2018 Jeep Wrangler JL Unlimited, we're going to be taking a look at and showing you how to install the Road Master 12 volt outlet kit, part number RN-9332.So here's what our 12 volt outlet kit is going to look like once we have it installed. We decided to tuck ours away underneath the dash, that way it's out of the way, but still accessible when we want to plug something in. This is going to provide us with 12 volts of power, whether the key is on or off. Which is going to be great for powering a portable braking system, whenever we flat tow our Jeep.Now we do have a 12 volt built into the dash, however, this is only going to get power when the key is in the run position, which isn't really going to help out a lot when we're powering our portable braking system, because the key is going to be off in our Jeep.Our kit is going to come with five feet of wires, so we can route it from the inside all the way to the battery. But keep in mind, it's probably a good idea to pick up some extra wire, plug connectors and ring terminals, because we we're just a little bit short on reaching the negative terminal on our battery.The instillation is going to be extremely straight forward. We're just going to have two wires to hook up and one bracket to mount.

Let's go ahead and show you how to do that, now. Keep in mind, this is only one component of our flat tow set-up.To begin instillation, we're going to need to find a spot to mount the bracket that's going to hold our 12 volt outlet. Now, we're going to be mounting ours on the drivers side, but for it to be out of the way and still accessible, we're going to mount it underneath the dash, right along the edge here on this metal bracket.Our kit is going to come with a couple self dabbing screws. So we can just go through the bracket and into the metal. Just keep in mind that you want the prongs to be sticking out so that can hold the socket, so it's facing towards you.

Now we're going to grab a three eights nut driver, and we'll just find a nice spot on the bracket, and we'll drill right into it.So we can grab our outlet now and on one end we'll have the outlet, and the other, we're going to have a spade terminal and a ring terminal. We're going to want to pass our wires with the terminals on, through our bracket, and for now, we're just going to pull all that excess out, so that the outlet can be held in place. And those little prongs that are on the bracket, they're just going to pull the outlet around, so it will be nice and sturdy.Now we're going to need to get our wires to our battery. If we look up on the fire wall, here, we'll find a plastic plug that we're going to need to drill a hole through that plug. Now it may be easier to move it to the outside or maybe easier for you to do it from the inside, you just want to make sure there's nothing on the other side that may cause any damage if you do use a drill, but you could use a knife or whatever you need to, so that we can pass our wires through.Now on the outside underneath our hood, our grommet is going to be just to the outside or towards the drivers side fender of our brake booster, here.

We see that plastic plug right against the fire wall. To give myself more room, I took a trim panel tool and popped that cover out so now that we've drilled the hole through our grommet, I'm going to go ahead and put it back in place. You just want to make sure you don't drop it, it is kind of a tight spot in here. We don't want to have to go fishing underneath our jeep.Now we're going to move back inside, and we're going to push the ring terminal and the spade terminal with the wire through our grommet so we can get access to it underneath the hood. We push everything through a little bit, grab our wire, we'll pull all that excess slack out.

It's a good idea to go back inside and make sure it didn't get caught on anything. With all the slack underneath the hood now, we're going to route it along the fire wall, make sure we secure it with some zip ties, so we can get to the battery on the passenger side.Now that we have our wires over to the passenger side, close to the battery, we're going to start with our power wire. That's going to be the one that has that inline fuse holder and that female spade terminal on it. Now we're going to be connecting directly to the battery instead of using the fuse tab and this female spade. So, I'm going to cut the spade terminal off, and we're going to strip back the end of our wire. I'm going to take a ring terminal and you can find these available here at eTrailor.com. Slide it over the end of my wire and crimp it in place. We'll have the solid point that we can connect directly to the positive post on our battery.Now on the top here, we're going to have several different posts, so we'll find the open one, take a 12 millimeter socket, and we're going to remove the nut. Then we're going to take our ring terminal and just slide it over the post and if you want, to make sure everything's going to be nice and neat, pass it under the cover, and then we can replace the nut.We're going to have one more connection, that's going to be our ground. But as you can see, it's not going to reach and depending on how you route it, you might be able to stretch it over, but I'd rather just cut this end off with our ring terminal, we'll add in a little bit of extra wire. Strip back the end, I'm gonna grab a buck connector, crimp it on place, and we can take our extra piece of wire, strip back the end of that, with the other end into our buck connector, and crimp it down. We need to estimate about how much of that extra wire we need, it's always a good idea to give yourself a little bit extra, just kind of follow the path of the negative battery cable, and cut our wire, we'll strip it back and I'm going to add the same size ring terminal to the end.This buck connector is a heat shrink buck connector, so I'm going to take a heat gun and shrink it down. Just keep in mind if you are using an open flame like a torch or a lighter, you need to be extra careful not to burn or char the connector or the wires themselves.So we can grab a 10 millimeter socket, and we're going to take the nut off of the negative post on our battery. I'll slide our ring terminal over and replace the nut. We can just tidy up all our wires, zip tie them with the existing wires, that way if they're ever doing any maintenance on the battery, this will come off with the battery cables.That'll finish up your look at the Road Master 12 volt Outlet kit, part number RM-9332, on our 2018 Jeep wRangler Unlimited.

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

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

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 735184

Have started installing them and they work well . My only complaint is the ground connector could have a little larger hole. 673900

Great, friendly service! Prompt service. Excellent price. Price matched on one item. Every item included in my rather large order. Will definitely use etrailer again. Appreciate pictures and information on each item. 596753

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

Simple and effective. 578649

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

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

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

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 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
