3. Attach the wire leading out to the external
source to the left terminal of the bus bar, 1,
(the terminal is marked “Audio External”).
4. Route the wire out to the external source
through the cover plate at the right rear corner
of the cab (See “Installation of Cab-Mounted
Accessories” in Section 1 for correct wire
routing).
5. The external end of the wire must be hooked
to a grounded sending unit of some type to
provide a ground source for the Electronic
Instrument Control System. An example of
this would be an oil pressure sending unit or a
coolant temperature sending unit on an
external engine.
NOTE: Any type of external grounding
source will work, but there must be a good
ground connection between the towed
implement and the tractor frame. Just
using the drawbar pin may not be
adequate, and a safety chain is suggested
for additional ground contact.
6. Reinstall the cover onto the electrical control
panel.
7. Reconnect the battery cables.
To disable the shutdown feature, follow this
procedure in reverse order.
NOTE: There is a secondary source for
connecting an external signal to the external
alarm control system. This source is the
number four pin (the bottom post) on the
four-post bus bar located in the right front
cab post, behind the gauge cowling. See
“Installation of Cab-Mounted Accessories”
in Section 1 for more information on the four
post bus bar.
