For vehicles equipped with ON-STAR, follow
the instructions on the following page before
starting.
A. Reconnect the battery.
B. Connect the supplied cable to the 9-pin con-
nector at the top of the hand-held unit. If
present use the thumbscrews to secure the
cable to the connector.
C. Connect the other end to your ALDL con-
nector located under the dash near the steer-
ing column. Make sure this connection is
seated all the way in and that it is secure.
You do not want this cable coming out of
the connector during programming.

"A", you can alter some predefined options
to suit your needs. These options are not
permanently stored in the hand-held unit.
When power is removed from the unit, the
changes you made will be lost.
F. You only need to press the YES button once
to start the programming cycle. The pro-
gramming process takes 1 minute and 15

disrupted, the computer will not start or run
your vehicle!

be turned off and the cable removed.
