Voodoo FBVC14DGU Digital Fused Distribution Block, Pt 1
Using an 8AWG copper terminal connector, I crimped a short section of the 8AWG power cable and attached it to the positive terminal of the battery...

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:
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.
)After much research and building comparison lists of pros and cons, I've finally made my selection. The chassis that will house the Acura ITX carputer is the Akiwa GHB-B05 from Guanghsing Industrial. I purchased the case with a 200W 1U PSU (mine was shipped with a 200W Sparkle Power PSU), which was handy for benchtesting the system rather than running it from my spare automotive battery, which required recharging every other day or so.
The chassis is very compact (measuring 11x11x3), and has room for 3 laptop hard drives and a slimline CD-ROM drive. It has front-mounted USB ports (which won't be used in this application, so the wiring for those ports was removed and stored), a large top vent, and an exhaust fan in the front-side of the case. The case has two rear PCI expansion slots (though only one is usable for PCI cards, the other for a USB or serial backplate connector), and ships with a PCI riser card...
)The photos shown in this post represent work that was performed over the last few evenings, and are compiled here into one set which will be easier to follow. First, the rear seats were removed to provide access to the trunk, and to make running wires under the carpet an easier process.
The seat bottoms required over 100lbs of force to lift up, but once the pressure housing gave way they were easily lifted out and set aside...

Building a kill-switch for the Acura ITX, Pt 1
Once the wiring to the dashboard was run, 3 separate 1/4" spade connectors were crimped onto 4 separate lengths of wire. One length is connected to the under-dashboard 12v power tap, which will provide the incoming 12V power from the battery. That wire was connected to the 'Power' terminal on the switch. The second length of wire was connected to the 'Ground' terminal on the switch, and added to an existing ground-point under the dashboard. It's a good idea to add a new ground wire to an existing ground-point rather than to select some random screw in the vehicle chassis to use as a ground.

The next stage of the Acura car computer fabrication process involved cutting a sheet of plexiglass to function as a stand-off layer between the metal headunit chassis and the burlwood ABS trim which will be visible to the outside...
)It was a very productive weekend for the Acura ITX carPC project. At the end of the day, the dashboard chassis is complete, and the only thing that remains is the faceplate mounting bracket and its related parts.

Fabricating the Dashboard Chassis, Pt 1
Picking up where we left off, the various cutouts have been made in the chassis which allow it to mount very snugly into the existing mounting bracket that is part of the dashboard in the Acura CL.
