ALARMS
There are four spare Alarm female ¼” slide connector breakouts behind the speedo-tach cluster near the speedo-tach
connector labeled:
• Alarm 1A
• Alarm 1B
• Alarm 1C
• Alarm 2
When these circuits are either grounded or powered an alarm sound in the dash will turn on. Alarm 1 and Alarm 2 have
two different tones.
SPARE SWITCHES FACTORY INSTALLED
Kenworth provides the option of coding for up to 5 spare switches with standard fuse locations in the central electrical
panel. These switches receive power from the Accessory bus. Switches 1 – 3 are fused by separate 15A circuit protection
devices (fuse or circuit breaker). Switches 4 & 5 share a common 20A circuit protection device. The location of these cir-
cuit protection devices are labeled on the central electrical panel cover. For example “SPARE SW #1” is the label for spare
switch #1.
These switches will be connected to backlighting, power and ground. A male ¼” slide connector breakout is taped back to
the harness. This is the switched power output, connect this to power your load.
