Ignition Signal: Wiring Diagram

For PG go to POWER SUPPLY, GROUND & CIRCUIT ELEMENTS .

Specification data are reference values and are measured between each terminal and ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
