I am nearing the end.... Finally...... (Well as far as the main PC is concerned. Still need to install the Raspberry Pi units, but they dont go on sale till May.) I got the last main piece, the rear battery. In the end I went with a Kinetic HC2000. I did so because I was able to get it locally. Now all I have to do is get the KVMP switches wired back up, but not before buying fuse holders and wiring to wire the 12 cigarette adapters I have to install. All this will get started today. I hooked the battery to the alternator, so it can build up a charge. After that I can hook up the car pc.
