tinues to blink, it indicates a fault with the fuel in-
jection system on Di models. Refer to DIAGNOS-
TIC PROCEDURES section.
Verification
The PURPLE wire is the 12 Vdc power source of
the Information Center.
The BLACK wire is the ground.
The RED/PURPLE wire is the 12 Vdc from the bat-
tery. It is protected by a fuse on the MPEM; the
fuse "MPEM" on the carburetor-equipped mod-
els and the fuse "ACC" fuse on DI models.
The accuracy of some features of the Information
Center can be checked with a potentiometer.
Fuel Level
Disconnect the 4-circuit connector housing of the
Information Center.
Using an appropriate terminal remover, remove
the PINK wire from the tab housing.
Reconnect the connector housing.
Disconnect the 2-circuit connector housing which
contains a PURPLE and BLACK wires.
