Summary
Western Star Service Bulletin for Connecting the Chassis Harness Connector to the Cab Front Wall 104-Way Pass-Through Connector. This bulletin describes how the chassis harness connector functions and how to verify the four locks of the terminal stabilizer plate on the 104-way pass-through connector are in pre-stage position. The terminal stabilizer plate is the white plastic plate located inside the 104-way pass-through connector. The stabilizer plate floats up and down in the pass-through connector to protect the terminals from being damaged when the chassis harness connector is removed and connected.
