I did manage to get a couple of things done today. The battery kit is just few steps away from being in, the cables ends will be soldered and connected the right way, by Gary of course. I will try to take a look for a good spot to drill the holes and mount the tray itself. I didn't get a chance to do it today as it was freezing cold, which limited my time in the garage to as little as necessary even with the heater on. Damn this Chicago weather!!
