Pro-Tip: HEUI (Hydraulic Electronic Unit Injection) systems are extremely sensitive to contamination. A single speck of dust can cause premature failure.

1. Connecting each plug of the wire harness to the corresponding hole on the test bench
2. Each time a switch is turned on, a function is tested. The corresponding indicator light turns on, indicating that the function is normal.
