Plug the sensor cable into the controller board, making sure that the pins are oriented
in the correct direction. You may replace the standard cable with a short extension
that would mate to a bulkhead connector.
With the controller board properly mounted, all cables connected, and excess wiring
cable-tied, the metal shield can be attached.
As mentioned earlier, it may be necessary to make changes to the metal shield and the
rear display housing to accommodate the sensor cable. Usually it is necessary to make a
hole in the shield and the housing so that the sensor cable can be routed through,
however some models may have an existing opening that can be used.
With a sufficient opening, the sensor cable can be fed through and the metal shield
reattached.
Note:
If a hole is drilled in the metal shield to accommodate the sensor cable, be sure to
fold back the edges or install a grommet so that the cable does not fray on the sharp
edges.
Note:
When routing the sensor cable through the metal shield and rear display cover, be
careful to avoid the inverter and other high noise sources.
Powering the Controller
After deciding where to mount the controller, it is necessary to determine how the
controller will be powered. As mentioned in the previous section, each type of controller
requires a different power source. Note that the controller must be properly grounded
through the mounting holes
