WIRING THE 12 PIN HARNESS:
BLACK: Chassis Ground Source
Connect the BLACK wire to a known vehicle ground source or to a solid clean metal part of the chassis. Be
certain to remove any paint or grease and secure this wire with a self taping screw and ring terminal.
BLACK w/WHITE: Saftey (Red Handled ) Control Switch
The BLACK w/ WHITE wire provides ON-OFF control of the Remote Starter. When the BLACK w/ WHITE wire is
switched to a full time ground, the CA 420A Remote Start Module is operative. When the BLACK w/ WHITE wire
is open, the remote starter is disabled. Connect the BLACK w/ WHITE wire to one of the wires from the back of
the previously mounted Safety (Red Handled) control switch. Connect the remaining wire of the control switch to
chassis ground. Always try to mount the switch so that the ON position is in an upward or toward the driver
direction.
GRAY: Hood Pin Input (-)
Connect the GRAY wire to the hood pin switch provided. This wire will be routed through the firewall into the
engine compartment. It is necessary to use an existing grommet when passing wires through the firewall to
prevent short circuiting. This is an important safety feature of CA 420A, and failure to use this feature can result
in serious injury. Route the wire to the pin switch and connect it using the bullet connector provided.
