Schematic for the wiring harness which is relatively simple.
I have the ACC override switch so that when the car is sent for wash/service the computer wont turn on or off repeatedly. The monitor is permanently powered but will go into standby when there is no signal from VGA. The amplifier is just like other aftermarket amplifier, permanently powered but brought up or down through remote terminal provided by M3-ATX. Ibus interpreter is always ON.
