CAN Terminators
Two CAN terminators (P/N 063-0172-369) are required for the CAN bus lines to
provide optimal signal integrity. The terminators are located at each end of the CAN
bus. The CAN power adapter “T” cable should be placed towards the front of the bus
with one end terminated. CAN power, obtained from a switched power source, run
throughout the bus to act as a shield.
Wiring Power to a CAN System
For the CAN system to operate properly, attention must be made to the wiring of
power to the Viper and to the CAN nodes. Many issues in CAN systems can be
traced to improper wiring of power and ground. Refer to the drawing below to prop-
erly connect you Viper and CAN system to power and ground.
Important:
 The Viper power must be wired directly to the battery and
not to switched power.
 All ground wires must be connected directly to the battery
ground, not to chassis ground.
 The CAN logic power must be wired to a Clean Power Buss
that is connected to a Clean Power Buss Relay.
 Use the orange wire from the Viper cable to control the Clean
Power Buss Relay.
 The CAN High Current Power must be wired to a High
Current Power Buss connected to a High Current Power
Relay.
 The High Current Power Relay is controlled by the vehicle
ignition switch.
