Okay, I finally have all of the components for my Enginer kit for my 2002 Prius. However, I've run into a few issues. First, the darned screw-holes didn't line up for the 3000W DC-DC converter. And they weren't off by far enough to drill new holes so I had to enlarge the existing ones. But, that aside, here are the questions I have. The kit is supposed to connect to 12V line on the car that is only on when the ignition switch is on. But the Enginer manual doesn't make any suggestions on where to connect this. Obviously I could use the line going to the cigarette/power adapter. But I'm betting there is a better place, any suggestions? It needs to be under the dash by the steering wheel, since that is where the switch is going to go. A fan with an 18" piece of very stiff plastic hose is included with the kit. Now, I know where the fan is supposed to connect with power, but I can't figure out where the fan mounts because there are no mount holes on the main box anywhere. I suspect the fan goes over the vents on the left side next to the DC-DC converter and there are a few vent-slots there. But where does the giant air-duct go? I received two toggle switches attached to little circuit boards with two LEDs on them. One of them is already inside of a little plastic knock-out, which does not seem to fit my 2002 Prius. (perhaps it goes to a 2004-09?) I'm guessing they just sent me two different kinds but I'm only supposed to use the one that goes to my car? I have the 2Kwh version, but I was under the impression that the box I have would be able to upgrade to a 4Kwh version. However, I've measured and there is not enough space (not by a long shot) for another 4 battery packs to fit in there. Does the 4kwh hour version come in a larger metal box?
