Connecting Tachometer

CAUTION: Ensure tachometer is compatible with ignition system. DO NOT allow tachometer terminal (IG-) to become grounded, as it could result in damage to ignitor and/or ignition coil.

Connect tachometer between chassis ground and terminal IG- of DLC No. 1. See Figure. See COMPONENT LOCATIONS .
