Tossing up a softball for you....
Wire harness that starts at the positive battery post - there are a number of positive leads (red wires) that attach to there.
Follow the casing down and the very first wire that comes off the casing seems to be a green wire. It is about 10" or so from the start of the harness that hooks to the battery.
Where does that green wire attach to?
Thanks,
Len
