How to Install the Roadmaster FuseMaster Fuse Bypass Switch on a 2019 Buick Envision


Instructor Hey everybody, how's it going Today we're gonna be going over and showing you how to install the Roadmaster Fuse Master bypass here on a 2019 Buick envision. So a fuse bypass is gonna be installed in individual circuits there in the fuse box of our vehicle. And it's gonna cut power to those circuits at the flick of a switch. And the reason we need this we're flat towing our vehicle because according to the owner's manual, we have to disconnect two fuses, while the vehicles in tow. That's gonna be fuse number 29 and fuse number 32. Now there's two fuses control, the body control module and those activate the lights, the locks, all the electronics in your vehicle.

And the reason we need to disconnect those while we're towing our vehicle, is that those are gonna draw power from the battery. It could potentially lead to a dead battery when we arrive at our location and get ready to start our vehicle and take off. That's certainly not something we want. Now I will say, this actual kit here, isn't a requirement. You can actually just open the glove box here, or our fuse box is located and manually pull out those fuse and re-insert them each time.

Let's face it that's a chore. We don't have to worry about losing those fuses. And it's just an extra step before we can hit the road, not something we want to do. If we can do all that at the flick of a switch, that's definitely gonna be something we're gonna be interested in. So let's go ahead and show you that now.

So the circuits that we need to cut power to are in the instrument panel fuse box, and that's gonna be on the passenger side, in your glove compartment. So open the glove box here and in this area here, you're gonna have a cover here. It's got a lightning bolt that's gonna signify that this is a fuse panel. So we'll pull that off in there, we can see our fuses. We look over to the right here.

You can see a couple of wires. Those are actually to our fuse master. So you can see here, we have a wire to each of the prongs here for each fuse. There's our 32, there's our 29. And then we have the wires tucked down there, ran to our switch. So here's our switch, this is the only thing we need to pay attention to when we get into our vehicle, when we're ready to either tow or take off down the road. And as you can see here, the positions are conveniently labeled. We have the white dot up in the drive load. So this is what we're just driving our vehicle around town. And then we have our tow mode here that we simply just press that. And that's gonna be what we're towing our vehicle behind our motor home. So in regards to installation, this one is very simple. It's definitely something you guys can do at home by yourself. We only have to drill one hole into the vehicle. The rest of it is gonna be completely plug and play. So let's go ahead and walk you through how to do that now. So to start our installation today, we need to locate the instrument panel fuse block, which for this vehicle here is gonna be inside the glove compartment on the passenger side. So we're gonna simply open up our glove box here. And then down in here, we're gonna have a cover here. That's gonna reveal, reveal the fuses, once we remove it, just like that. Now, if you actually look on the back of the fuse box lid, there's gonna be a fuse diagram, which remind me to turn it, to hold it correctly, to match up with the fuse orientation. But then we're just gonna simply find the 29 and 32 fuse slots, which are gonna be on this side here just a couple up and then a couple up more there. We need to remove the tenant fuses. If you have a pair of needle-nose pliers, there should be a fuse holder, somewhere in the vehicles, name fuse box under the hood. If you'd hold a remover, but if not, needle nose works great just to get those two micro fuses out. Now, once we have those out, we're actually gonna be taking our harness here, bypass harness. And there's gonna be a nice little space underneath the dash here. You can sort of see my fingers through there now. So you're gonna remove the switch from the harness, and then you're going to feed the wires up in through that little passage out the bottom. And they can actually slide behind this panel here in between the fuse box. So you're gonna be routing the side up here with the pins that go to the fuse terminals. So the instructions tell you to not insert the fuses to the end, but the way that we have our harness routed, the fuses are gonna be in there, by the time we get the switch mounted. When we get our pins in the terminals. Therefore we're not gonna have access to do that. So you can go ahead and insert your fuses now, you just need to be careful that the terminals on the two wires aren't touching, But now that we have the four wires here that go from the harness, they're gonna be plugging into the fuse box. We have two black and then two red. Normally you'd want to be careful about what you're, which fuses and wires you're attaching to which circuits there, because you would need to then insert the corresponding fuse into that wire that matches up with that. But in this case, they're both 10 amps, so you really don't have to worry about that. Just make sure you have two black pins going to one of the fuses and then two red pins going to the other. And again, the terminals we need are 29 and 32. So if we use that same set of needle noses, we use to remove the fuses, you can easily pin those into the terminals, that makes it a lot easier, but it's really not that hard. For this particular application, we use the two black wires, the two black pins going to the top, number 32 fuse, and then the two red ones going to the bottom, which is the 29th. So now we're gonna actually install the switch here. So this is a button we press when we want to drive, or we're ready to tow our vehicle, that's gonna cut power to the fuses. So for starters, you're gonna take a seven millimeter socket, there's gonna be one screw right up here, you'll simply remove that. And that's gonna give you a little bit more room to work cause you can kind of bend this panel down. But we're not gonna be removing it completely, nor are we gonna be removing any other screws. Once we have this panel down, we're gonna take a three quarter inch drill bit. Chances are, you're not gonna have a single three quarter inch drill bit. So step drill bits work really good for this. We're just gonna drill a hole in this panel here. So once we get that hole drilled, we're gonna take our wiring harness, which we can actually see it here. It should be hanging down in this area anyway. So it shouldn't be too hard to locate. So on the back of your switch here, you're gonna get a little, I'm trying to think a jam nut. So a jam net with some teeth on it, that's actually gonna help secure the switch to this panel. So you're gonna stick that jam nut over your wires. And then you're gonna feed your wires out through this hole in this panel here. And then we can attach them to the back of the switch. Now, again, I said earlier, we needed to be careful if we are using different amp fuses, because the pins in those locations of the wires need to correspond to the fuses. But this is just two 10 amp fuses. So it's not gonna be a big deal. Just make sure you match the color side to side. In other words, I want two black pins on this side and two red pins on this side, they do come pre attached, but we have to remove them in order to install the switch. And again, needle nose pliers are gonna be your friend when you're working with those terminals. But now we're just gonna pretty much pull the wires through that hole there we made. And then we're just gonna use the needle nose to press them onto the back of the switch. I'm going to press the switch into the panel there through the hole we drilled. And I'm gonna reach back there when pulling the panel down. And I'm gonna use that jam nut to secure the switch to our panel. And now all that's left to do is to pretty much re secure the panel here with that screw and install our stickers. And then we can test the system out. So this is a pretty easy to system to test right now, we're in drive. So this is everything gonna have power. But if we go to tow mode, turn that off. We should see the lights kick off. So that's one indication. Another indication is go ahead and try to use your door locks on the door. They shouldn't work at all. Shouldn't have power to any of that stuff. But if we go ahead and hit drive again, it takes a little while for the system to boot up, but you should see your lights come back on and you should have power to the door locks once again. Look I can hear the door locks actuating, so I know everything was hooked up and it's working correctly. And that's gonna do it today for our look at installation of the Roadmaster FuseMaster bypass here on our 2019 Buick envision..
