A 6-pin low power Molex connector is provided for the CAN Bus interface.
However, the CAN Bus option must be specified for this interface to be active.
The mating connector is a Molex Mini-Fit Jr. p/n 39-01-2065 using type 5556
terminals.

The +15V supply should only be used with the CAN system or speed sensor
and not to power any other external systems.
The L and H terminations provide a 120Ω termination impedance for
the CAN H I/O and CAN L I/O inputs if necessary. Refer to the Curtis CAN
Protocol Document to determine the proper termination for a given application.
A 4-pin low power connector is provided for the handheld 1313 programmer
or 1314 PC programming station. A complete programmer kit, including the
appropriate connecting cable, can be ordered from Curtis.
If a programmer is already available but has an incompatible cable, the
1244 mating cable can be ordered as a separate part: Curtis p/n 16185.

and reduces the mounting hardware necessary for the
power connections. The tightening torque applied to
the bolts should not exceed 16.3 N·m (12 ft-lbs) for
the M6 bolts or 20 N·m (15 ft-lbs) for the M8 bolts.
Exceeding these specifications could damage the bus
