On mine, the high resistance coil is the sense coil (5k),
and the low resistance appears to be a calibration
coil. The third pair was unconnected on my unit
There are only 2 pair leading into the case, although
there were 3 pair at the circular connector. If you're
running a non-feedback arrangement, you can
leave the low R coil disconnected.
