To connect voltmeter onto self-test connector, proceed as follows:
1. Insert end of jumper wire into the No. 4 pin on self-test connector.
2. Clamp negative lead from voltmeter onto other end of jumper wire, Fig. 11.
3. Clamp positive lead from voltmeter onto positive battery terminal, Fig. 12.
4. Insert one end of second jumper wire into No. 2 pin on self-test connector and other end into self-test input connector, Fig. 13. The final connection also activates the ECA self-test sequence when the ignition switch is turned to the ON position.
