Yellow Wire:
Accessory Output
Connection Required
.
Connect the Yellow wire to the vehicle's Acces-
sory 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 on page 11).

Black Wire:
System Ground
Connection Required.
Connect the Black wire to a very good, clean chas-
sis ground. A recommended connection is to an existing machine-thread bolt,
either in the driver's kick panel, steering column area or a major structural mem-
ber behind the dash. Small dash braces are not adequate, and the area must be
clean, bright metal. Use of a sheet metal screw or otherwise grounding to the
vehicle’s sheet metal is least desirable, and in some cases will result in an inad-
equate grounding of the system.
