The 4-Pin Injector Harness is used to measure
continuity of the UVC wiring and injector solenoids.
12-Pin Breakout Harness
Figure 524 ZTSE4665
The 12-Pin Breakout Harness is used for circuit
diagnostics for the Injector Drive Module (IDM)
powers and ground, actuator power and ground
(EGR and VGT), in addition to some applications
(IAT, service brake switch signals to the ECM, and
ATA data link to and from the IDM).

The 500 Ohm Resistor Harness is used for operational
diagnostics of sensor circuits and Output State Tests
for actuator control circuits.
Actuator Breakout Harness
Figure 526 ZTSE4484
The Actuator Breakout Harness is used to measure
the voltage supplied to the Injection Pressure
Regulator (IPR).
For electrical circuit diagnostics, install the breakout
harness between the electrical harness and the
valve. For Injection Control Pressure (ICP) system
diagnostics, plug the Actuator Breakout Harness into
the IPR valve only.
