Replaced our original HWH level sensor with new electronic level sensor

Replaced our original HWH level sensor with a new style electronic level sensor.  It is mounted centered between front & rear axles and side to side on our big bay's ceiling.  I ran the cable to HWH control box above house battery compartment.

The original level sensor was fastened to the floor under a kitchen cabinet and used mercury to sense when coach was not level.  HWH panel indicated level sometimes when we still off a little.  I did improve it a little by adjusting the original level screws.  HWH converted to electronic level sensor, partly because the original used mercury.

After mounting new level, I just unplugged original sensor, plugged in new sensor and made a new power connecton

HWH parts RAP-91734 (cable kit) and RAP-91031 (sensor) cost $300 and also included  AP-30631 (short 12-volt power harness) and AP-29299 (three bolts & springs to mount sensor).

Initial one-time adjustment is simple.  We will report if our leveling is improved after we hit the road.
