Everything You Need to Know About Power Magic Pro

Hello, Alex from BlackboxMyCar.com here. Today, we are going to show you how to install a Power Magic Pro, or PMP into your car. Before we get into that though, I’d like to talk about the importance of hardwiring a Dash cam with a dedicated parking mode. Some Dash cam owners only want to record when they are driving, and some Dash cam owners want protection even if they aren’t in the car and when the car is turned off. Those who only want a Dash cam that’s on when the car is on as well can use the “Plug & Go” method, which means they simply plug the Dash cam into their car’s cigarette jack and leave it plugged in. These customers may think “My car has a cigarette jack that has a constant charge. I don’t need a Dash cam with a dedicated parking mode, or a hardwiring kit!” The thing is, when a dedicated parking mode system is paired with a hardwiring kit, it is one of the most effective and energy efficient ways to keep your car protected at all times.

What is PMP?

The Power Magic Pro, or PMP, is one of our most popular products for managing parking mode functions. A PMP is hardwired into the car to detect the voltage levels of your car’s battery. This is vital so that the Dash cam will know when to cut power so your vehicle will have enough charge to start up.

Now the instructions I’m about to give are going to be as general as they can be, because different cars have different fuse setups.

Hardwiring Step 1: Identifying

The first thing that you will need to do is find out where your Fuse Box is located. This is different for every model of car, but there should be more information on this within the owner’s manual. Once you have found the Fuse Box, we can begin hardwiring your PMP into your car. Preferably, we go for fuse boxes that are located in the cabin as these are the easiest ones to work with, unlike the ones that are located under the vehicle’s hood.

When hardwiring the unit, you will need to focus on three wires. The first is this black ground wire. The ground wire exists to mediate the voltage going to the units, and needs to be hooked up to the grounding bolt, here. You can do that by unscrewing the bolt a little bit, and placing the two prongs from the wire into the gap between the bolt and the frame. When the prongs are in, tighten the screw, just enough so as to not break the wire.

Circuit Tester

The second wire you need is the Red ACC wire. This wire needs to be placed in a fuse that isn’t on when the car is off. The fuses that you can use vary from car to car, so you will need to test your fuses using a circuit tester like this one. Now I know that I haven’t told you how to get this Red ACC wire into your Fuse Box yet, but first we need to talk about the last wire.

That last wire is the Yellow Constant wire. This wire is much like the Red ACC in that you will need to find a fuse that you can put it into. The main difference is that the constant wire will need to be in a fuse that runs constantly.

Hardwiring Step 2: Implementing

With the wires identified, we can now take a look at the Fuse Box itself. It’s important to note that Fuse Boxes vary, and while there are some groups of cars that have similar layouts, the fuses that can be used may be different from car to car. Use the aforementioned circuit tester on the fuses; fuses that cause the tester to light up when the car is on and the car is off are considered “Constant Fuses” while fuses that light up only when the car is turned on are “ACC, or Accessory Fuses”.


Once you’ve found one that will work out well for your two wires, you have two options on how to actually get the wires into their fuses. One is to wrap the metal tips of the wire around the leg of the fuse you’re using, while the other is to use what’s called an Add-a-fuse. When using an Add-a-fuse, you only need to place the tips of the wire into the slot of the Add-a-fuse and clamp them down together. After the wire and Add-a-fuse are connected, take the fuse out of the slot that you want to use, and place the fuse in the empty fuse slot on the Add-a-fuse. After the pieces are put together, you can place the Add-a-fuse unit into the empty slot in the Fuse Box.


With the wires and the fuses all set up in the Fuse Box, your Power Magic Pro should be all set up and ready to begin managing your Dash cam. After finding a good place to place your PMP, you can connect it to your Dash cam through it’s female Cigarette port by placing the male end from the Dash cam into it. With it all setup, your Dash cam should turn on and stay on to provide surveillance for you.
