Once opened, what you’ll need is the Thinkware Hardwiring Kit. This consists of three wires: Constant power, which is the Yellow wire, the ACC or accessory Red wire, and the black grounding cable. If you’re confused about which wire is which, you can always read the label that’s on the respective cable too, as other camera brands may change the function of each cable.
Starting with the black ground wire, the C-shaped connector needs to be grounded to an unpainted metal bolt or stud in the vehicle. This should be the first thing you do to protect yourself from shocks or electrocution and allow excess voltage to flow into the earth during a short circuit. We found an unpainted grounding bolt right near the glovebox for this install, using a socket wrench, we loosened the bolt enough to slide C-shaped connector underneath, before refixing the bolt.
Next, take both the red and yellow wires, and connect them to their Add-a-Fuses with the proper fuse taps. While add-a-fuses aren’t required, they are quite helpful for an easy install, making it easier to piggyback off of existing fuses.
Using your needle nose pliers or a crimping tool, trim off some of the rubber tubing if necessary to expose some bare wire of your hardwiring cable. Insert the hardwiring cable into the other end of the add-a-fuse (plastic tube), then crimp them down together to make the connection. Test out different fuses to know which would be ideal for each connection type.
The fuse tap that you choose is dependent on the car, from ATO, Micro2, Low-Profile and Mini. For this VW Taos and many European and Volkswagen cars, ATO fuses are used. We used 20A fuse taps and wired to 20A fuses. Make sure the fuse tap you’re adding is equal to or higher than the existing fuse you are connecting to
