MOUNTING
The MCL-4000 series gauge requires a round hole 1-7/8" diameter. It should be inserted into the opening from
the front and the U-clamp will be installed from the back. Tighten the two nuts on the U-clamp so that the gauge is secure.
Gauge depth to the back of the case is approximately 1-3/8". Gauge depth including the mounting studs is about 2-1/8".
PRESSURE GAUGE SETUP
The green wire in the harness is used to enter setup and change/select settings. This is done by powering the
green wire with +12V or releasing it. To power the green wire, touch the wire to a +12V source. To release the wire,
remove the green wire from the source. The gauge moves through the setup in the following order:
