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
diagram

3 on page 14)

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 14)
.
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 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

W I R I N G - 10 WIRE CONNECTOR
Black Wire:
Connection Required
Connect the Black wire to a very good, clean chassis ground. Recommended
areas are to an existing machine thread bolt, either in the driver's kick panel area or
a major structural member behind the dash. Small dash braces are not adequate,
and the area must be clean, bright metal. Use the largest existing machine threaded
bolt available (see diagram #4). Using a sheet metal screw or grounding to sheet
metal is inadequate (see diagram #5 on the page 17).
