Installation Guide

Harness Description
When connecting the Module, it is important to make sure the connector with the Ground wire is
connected first before making the 12-volt connections. Should the unit be powered before being
grounded, there could be serious damage to internal components of the unit. Be careful not to
power up a Module before it is properly grounded. To avoid any accident, it is recommended to
pull out the fuses from their sockets before the installation, and to put them back during the very
last steps.
6-Pin Main Ignition Harness
Wire
Description
A
RED
+12 V
Battery
Connect to the largest 12 V supply wire at the Ignition harness. Ensure
that the OEM power wire is fused for more than 30 A.
NOTE: certain new vehicles have no suitable 12 volts source at the
IGNITION switch (the 12 Volt wire is too small to supply the necessary
current). In this case, the fuse box, or the B+ connection on the battery
is recommended.
B
PURPLE (+)
30 A
starter
output
Connect to the Starter wire of the vehicle (at the IGNITION switch).
The source wire should have +12 V with the Ignition Key in the
CRANK position only.
C
RED
+12 V
Battery
Connect to the largest 12 V supply wire at the Ignition harness. Ensure
that the OEM power wire is fused for more than 30 A.
NOTE: certain new vehicles have no suitable 12 volts source at the
IGNITION switch (the 12 Volt wire is too small to supply the necessary
current). In this case, the fuse box, or the B+ connection on the battery
is recommended.
D
YELLOW (+)
30 A
Ignition
output
Connect to Ignition wire of the vehicle. The source wire should have
+12 V with the Ignition Key in the IGNITION ON (RUN) and CRANK
positions.
Warning! Some vehicles have more than one IGN wire at the
IGNITION switch for powering the heater blower motor. Use the 5th
relay (pin F) and extra relays to power up any extra IGN. wires if
necessary. DO NOT JUMP WIRES at the IGNITION switch, this will
compromise the OEM electrical system.
E
ORANGE (+)
30 A
Accessories
output
This wire is for powering the heater blower motor. It is usually classed
as an ACC. (no power in the CRANK position.) if it tests as an
IGNITION (power in the crank pos.) then power it as an IGNITION (5th
relay, or extra relay).
Warning! Some vehicles have more than one ACC wire at the
IGNITION switch for powering the heater blower motor. Use the 5th
relay (pin F) and extra relays to power up any extra ACC. wires if
necessary. DO NOT JUMP WIRES at the IGNITION switch; this will
compromise the OEM electrical system.
F
GREEN (+)
30 A
5th relay
output
This high-current output can be used to power a 2nd IGNITION or a
2nd ACCESSORY or a 2nd STARTER WIRE. See jumper settings in
5
th
relay section later in the guide for correct output position (page-15).
Additional IGNITIONS, ACCESSORIES, or STARTER WIRES must
use external relays. DO NOT JUMP WIRES at the IGNITION switch,
this will compromise the OEM electrical system.
