Not for an HCH, but it's essentially the same as the Insight. I marked each step in the wiring a different color. Green is motor to rectifier, blue is rectifier to PSU, red is PSU to the front of the car to the 12v battery.

There's basically just a long 8 gauge wire from the 12v battery to the back of the car already, makes this all very easy.

Probably around 33%. I'd say 70mpg is a realistic but non-trivial goal in an HCH1, while 90mpg is a realistic but non-trivial goal in an Insight (for a full tank). You can reach either with a completely stock car and consistently careful driving.

Of course, points in the HCH1's favor are that MPG is not a very good metric. 70mpg is 3.3L/100km, while 90mpg is 2.6L/100km. In an absolute sense, it's the same amount of fuel saved as going from 25mpg (9.4L/100km) to 27mpg (8.7L/100km), because both cars already use so little.
