WARNING: This page is about a different car, the 2002 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Reversing the connection of the tachometer will damage the transistors and diodes inside.
When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks.

Connect a tune-up test tachometer, and start the engine.
Compare the tester and tachometer indications.
