Great, thanks very much- I think I'm finally starting to understand this craziness. (about time, right!?)
Anyway, just to clarify because I'm not sure I was reading the white wire's voltage properly before...
The the KEY in my pocket, ie: not in the bike, and ignition off, the white wire reads 0.00 Ohms (when tested against my bike's ground aka: frame). When I turn the ignition on, that white wire now reads 12v with in the same experiment.
Does this mean it's a ground wire, or is it still acting crazy? Either way, I think i'm good to go, and will hopefully try mounting it up this weekend.
Thanks,
Chuck
