Fuel Injectors: Notes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 Ford RV Cutaway, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Econoline, and 2003 Ford E450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Ensure negative battery cables are disconnected before disconnecting engine wiring harness. The Injector Driver Module (IDM) supplies 115-volts DC into each fuel injector connected to engine wiring harness. Severe electrical shock hazard exists. DO NOT pierce wires.
