  3. Disconnect negative battery cable. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Check for one ohm or less resistance from cluster connector C1, pin No. 16 (Black/White Wire) to ground. Check for one ohm or less resistance from cluster connector C1, pin No. 15 (Tan/Yellow Wire) to PCM connector, pin No. 48 (Tan/Yellow wire). Connect battery. Turn ignition switch to ON position.
