Now that your dash cam is mounted, let’s get it wired! For the Audi Q4 E-Tron, the fusebox is located on the driver’s side, just on the left, below the steering wheel. Starting from the front camera, we wired across from the driver’s side of the windshield, through the headliner, to the side A-pillar. You can use the pry tool or a flathead screwdriver to remove the plastic trim pieces along the A-pillar. This fusebox runs power off of the accessory battery, and not the main electric battery.
European cars like this German Audi E-Tron have really tight and rigid trims, so this could be one of the tougher challenges when wiring. But with the right tools (and patience), we’re sure you can do it. Just be careful not to damage any of the wires or components while removing the trim pieces, and wire behind/around the airbag as needed. Thinkware’s thin cabling is also quite helpful with this.
The hardwiring cable for the Thinkware U1000 is a 3-wire connection, with one for ACC (ignition-based), one for constant, and one for a ground connection. Here, we recommend using a circuit tester, like the one that comes with the essential install package to test out different fuses to determine which will be ideal for each connection type. The ground should be a clear unfinished metal connection, such as an existing bolt in the vehicle.
This setup will allow the camera to power on when the vehicle is off of the constant connection, and the ignition connection will tell the camera when the vehicle turns off, and to go into parking mode. The most common ignition connection our installers look for immediately is the Cigarette fuse. Cigarette fuses are normally very consistent in how they operate, and offer a clear way to test their powering parameters.
Remember, the fuse tap that you choose is dependent on the car that you use, from ATO, Micro2, Low-Profile and Mini-Fuse. For this Audi Q4 E-Tron, it actually uses ATO Fuses. Do consult your user manual to find which one is right for you, and also, make sure the fuse tap you’re adding is equal to or higher than the existing fuse you’ve chosen. We also advise you not to use any of the fuse slots used by any of your vehicle's critical components, such as the airbags and engine modules, for safety.
Once you’ve determined an appropriate fuse, we can get to connecting to it, either using the add-a-fuse kit included with your Essential Install Package, or you can wrap the hardwire kit around the legs of existing fuses in the fusebox.
