Running the System Wires, Pt 1

Continuing with the wiring run, wires were fed down the length of the centerline of the car. These wires provide:

  • power to the LCD screen, which will be powered from a standard computer molex connector via the OPUS120, which will provide a regulated 12V current to the screen
  • grounding for the LCD screen, which is connected to the same molex connector as the screen power
  • the ACCessory wire for the OPUS 120 ignition signal
  • a pair of 3.5mm Audio cables for connecting to the MIC and LINE-IN connectors on the computer system
  • a pair of USB panel-mounted connectors
  • VGA cable for bringing the video signal to the touchscreen
  • a pair of RCA cables with video for connecting to the VIDEO input of the screen, and for splitter connection to the Alpine headunit

The main RCA Audio cable is a 4 meter length of triple-shielded oxygen free RCA cable, and was run down the passenger side of the vehicle, keeping it as far as possible from the assorted power cables.

With the rear seats removed, running cables to the trunk is a simple matter. Here we see a USB cable, and the pair of 3.5mm audio cables lying across the underside of the seat floor, along with a spare length of 14AWG wire for future power requirements...

...and here we see the remainder of the wires for power, ACC signal, USB, etc.

Running computer and power cables down the vehicle's centerline

Using the dremel grinding stone, I cleared away the surface paint from the chassis and then drilled a 1/8in hole through the frame. Using a self-tapping screw, I connected the ground wires for the OPUS120 and the VOODOO distribution block, securing them to the exposed metal of the vehicle's frame.

Here is a shot of the exposed wires in the trunk, just waiting for the system to be hooked up.
