2. Connect WHITE/RED wire to a valid Tach source.
3. Start engine with key.
4. Press program button 5 times, then wait for 5 light flashes.

press. This unit is now at option #4-Tach Learning.
6. A) RS900ER III: Press Button #1 remote transmitter . The unit will read the Tach source and flash the lights twice
for program confirmation.
6. B) RS901 III: (No Remotes) Press the brake pedal to program the Tach Source.

RS900 III will automatically go into “Smart” Tachless” mode to allow the unit to continue starting the engine.
