If you will be remotely mounting the MTU,
refer to Publication 471-2000, General

and mounting of STAR MTUs. Continue
to Step 12 if you will be mounting the

NOTE: The pulser and MTU can be
supplied pre-wired or as separate
assemblies. If provided as separate
components, connect the three wires in
the pulser cable (red, black, and white) to
the corresponding wires in the MTU
cable.
