attach the base completion label (Form WAR259). If a field service kit is not required or there is no completion
sticker in the kit, write the campaign number on a blank sticker and attach it to the base completion label.

Work Instructions
Subject: Western Star ECC Park Brake Output Signal
Models Affected: Specific Western Star, 4700, 4900, and 6900
models, with Cummins EPA10 engines manufactured between
May 12, 2010, and January 29, 2013.

Parking Brake Air Pressure Switch Installation
1. Check the base label (Form WAR259) for a completion sticker for SF483 (Form WAR260) indicating this work
has been done. The base label is usually located on the passenger-side door about 12 inches (30 cm) below
the door latch. If a sticker is present, no work needs to be done. If there is no sticker, proceed with steps
below.
2. Park the vehicle on a level surface, shut down the engine and set the parking brake. Chock the tires.
3. Exhaust the air from the air system.
4. Loosen the main and secondary dash panels and move them out of the way.
5. Locate the black park brake supply air line as shown in Fig. 1.
6. Inspect the installation to determine if an additional air pressure switch has been installed in the park brake
supply line as shown in Fig. 1, and that wires 440X and 440G have been relocated from the electronic control
center (ECC) to the switch.
If wires 440X and 440G have been relocated to a separate switch, no further work is needed. Secure the
dash panels and go to the last step.
If wires 440X and 440G have not been relocated to a separate switch, and are still connected to the ECC as
shown in Fig. 2, go to the next step.

7. Install the tee and air pressure switch (from the kit) into the park brake supply air line. See Fig. 1
8. Using parts from the kit, attach the terminals and connectors to the ends of the new wires.
9. Connect the new wires to the new park brake air pressure switch.
10. Route the new wires back along the existing wire loom to the ends of wires 440X and 440G and trim off any
excess length.
11. Remove wires 440X and 440G from the ECC connector pins G and H. See Fig. 2.
12. Remove and discard the existing terminals from the wire ends of 440X and 440G.

IMPORTANT: The crimp, solder, and seal connectors need to be heated to 100 F (38 C) for best results. Distribute
the flame evenly — do not isolate it to one area. Heat the connection until the solder flows into the wires.
13. Using the crimp, solder, and seal Butt connectors (from the kit), connect the new wires from the new park
brake air pressure switch to wires 440X and 440G.
14. Remove any zip ties and clamps as needed and fit the new wires to the new switch into the existing wire loom.
Install all clamps and new zip ties as needed.
15. Clean a spot on the base label (Form WAR259), and attach a completion sticker (Form WAR 261) for campaign
SF483 to the base label.
