Connecting Auditory Tubes to ECUs
IMPORTANT: Do not cut or change the length of the auditory tubes. This will cause incorrect
readings.
1. Remove the caps from the ECU ports that you will be using, beginning with ECU port 1.
You will use one ECU port per sensor on the manifold. The number of ECUs you use
depends on the number of runs per manifold.
