Sean goes over all of the wires that go into the dash from the computer, amplifier, and other peripherals. The BoomzBox is also installed into the dash behind the monitor. This is secured to the frame of the dash with adhesive tape and large zip ties. Backup camera wiring is extended to the backup light. When this wire gets +12V, the Lilliput monitor will automatically switch from PC to AV2, displaying the backup camera through this input. A vehicle specific wiring harness eliminates the need to splice into your factory wiring.
