installing new power control board on L700i HRT1592 Healthrider. Black wire from two-pin HD6 connector (just above slo blow fuse) on upper right corner of board is loose and not connected to anything. OEM wiring schematics do not show HD6 or HD7 at all. Need to know what that wire connects to. If you have an L700i Healthrider and can take a look at that wire and what it connects with, much obliged.
