Green Wire:
12-Gauge
Connection Required
Connect the Green wire to the vehicle's Starter Motor wire. This wire will show
12 volts only when the ignition key is in the "Start" position. This wire is also found
in the ignition switch wiring harness
(See diagram
#
1 on page 9)
. Some vehicles have
a second Starter wire known as a "Cold Start" wire. When this is encountered, if
the two Starter wires are the same circuit you may connect both of these wires to
the Green wire. If the two Starter wires are separate circuits an optional prewired
dual relay socket and relays are recommended.
Note: If a security system is present which utilizes a starter interrupt circuit, the
Green wire must be connected to the Starter Motor side of the interrupt.
Blue Wire:
12-Gauge
Connection Required
Connect the Blue wire to the vehicle's Ignition
#
1
wire (also known as Primary
Ignition)
. This wire will show 12 Volts when the ignition key is in the "Run" and
"Start" positions and no voltage in the "Off" and "Accessory" positions. This wire is
found in the ignition switch wiring harness
(See diagram
#
1)
.
Note: If two or more Primary Ignition wires are present, you will need to connect an
optional relay(s) to the thin Blue wire located in the 3-pin Blue connector
(See

.
11
Yellow Wire:
12-Gauge
Connection Required
Connect the Yellow wire to the vehicle's Accessory wire. This circuit supplies
power to the Heat, Ventilation and Air Conditioning (HVAC) system. This wire will
show 12 Volts when the ignition key is in the "Run" and "Accessory" positions and
No voltage in the "Start" and "Off" positions. The connection point for this wire is
also found in the ignition switch wiring harness
(See diagram
#
1).
Note: If two or more Accessory wires are present, you will need to connect an
optional relay(s) to the thin Yellow wire located in the 3-pin Blue connector
(See

W I R I N G - 3 WIRE "BLUE" CONNECTOR
Blue Wire:
(22 Gauge)
The Blue wire will supply a 500ma Negative Ignition output that can be used to
operate an optional relay
(s)
if two or more Primary Ignition wires are present in the
vehicle. If an optional relay
(s)
is needed, Connect the Blue wire to the Negative
side of the relay's coil
(See diagram
#
2 on page 13)
.
Red Wire:
(22 Gauge)
The Red wire supplies constant 12 Volts that can be used to power the relay's
coil.
Warning: DO NOT use the Red wire to power the Ignition or Accessory circuits.
Yellow Wire:
(22 Gauge)
The Yellow wire will supply a 500ma Negative Accessory output that can be used
to operate an optional relay
(s)
if two or more Primary Accessory wires are present
in the vehicle. If an optional relay
(s)
is needed, Connect the Yellow wire to the
Negative side of the relay's coil
