Looking for electrical schematics
I'm trying to diagnose a AIR injection pump code but don't have the schematic of the power center to determine the correct relay for the pump. Would anyone have a schematic or know where I could get access to one?
Thanks

AIR Pump Relay is #43. However, Ign Relay #42 supplies actuation voltage to #43 through Engine Ignition Fuse #19. When the PCM grounds the air pump relay line the current flows through 42 and 19 and then through 43 which then closes so current can flow from fuse 50 through the AIR motor.
