DDEC VI ELECTRONIC CONTROLS APPLICATION AND INSTALLATION

VIH Power Wiring

The OEM-supplied VIH power wiring (see Figure 3-11) supplies 12 volts to the CPC and MCM.
The system must be sourced directly from the battery. The terminals are designed to accept 14
AWG wire with an insulation diameter of 3.2 mm minimum and 5.6 mm maximum.
Figure 3-11 Power Wiring
Power and ground must be sourced directly from the battery. An electrically solid connection
to the battery or bus bar is required so the battery can filter electrical noise from the power
lines. Power for other vehicle systems must not be sourced from the VIH power wires. Do not
use chassis ground.
NOTE:
The ground wire must be electrically separate from chassis ground.
