Allow me to simplify...
1. Turn Ignition switch to "run"
2.
Immediately push the trip odometer button
twice
3. Within 10 seconds of doing step 2, turn ignition switch off.
4. Press and
HOLD the trip odometer button.
5. While holding the odometer button move the ignition to run.
6. Continue holding the odometer button for about 10 seconds, or until you hear the beep.
Hope this clears things up!
OH...I almost forgot, spensley's step...
7. Peel off the sticker!
