The OBDII data lets us read current out of the DC-DC convertor so power used by various things can be determined by switching then ON and OFF. Consider these as "ballpark" values as current out of converter constantly jumps around by up to +/- 4 amps. Will add various items to this post as they get collected.
ReadyTo-Run: About 200 watts - nothing else turned on.
Outside Lights: Parking/Low Beam/High Beam = 75 / 220 / 363 watts
Inside Roof Lights: Insignificant, can't measure, certainly less than 10 watts
Heater Fan: Speeds 1 / 3 / 5 / 7 = 25 / 50 / 130 / 220 watts
Seat Heaters: Both set to '1' = 145 watts
Power Steering: 45 to 110 watts from HVB (not DC-DC). Measured sitting on concrete while turning wheel +/- 1/4 turn at about one cycle per 2 seconds, then 1 cycle per second (the higher reading). Surprised it was so low but expect it could be a lot higher on the road (?) since its powered from the HVB.
