Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
