Is a J1939 Protocol available? If so, how can I gain access to it?Answer: With the 2010 model year trucks or newer the J1939 protocol is available via the diagnostic connector located at the lower left hand side of the dash and new nodes can be added at the end resistors. See Page 1A-7 and 1A-8 for location and connection details
Is there any factory provisions for remote Stop?Answer: Yes remote Stop is available using Option code 162-018 based onthe engine configuration. Availability would need to be determined by the Sales and Application Engineering groups.
Is there any factory provisions for remote Start/Stop?Answer: Yes remote Start Stop is available using Option code 157-004 for the 4800/4900 models. Customer supplied harness with 4 position switch is supplied by customer for this option See Page 1B-18 for more details.
How do I get remote Engine Speed Control (ECU)?Answer: This option can be requested on new orders via data code 163-008 or 163-009. If these options are not present, remote engine speed control can alsobe accessed via the JS19 connector located in the engine compartment and is part of the main engine harness A06-63518. See Pages 1B-19 and 1B-20 for schematic information.
Can you get a fast idle interface on the WSTAnswer: data code 148-035 provides a fast idle switch interface tied to the parking brake See schematics on Page 1B-21.
Answer: The 4700 electrical architecture is the same as other WST models but has different pin locations in the front wall. These differences are defined in the pin out charts in this chapter on Pages 1B-3 through 1B-9
Answer: The instructions to disable the brake override circuit are located on page 1A-22
Answer: The WST electrical turn signal system requires a minimum amperage load from the tail light system. When LED lights are used a resistor needs to be added to increase the load to anacceptable level. See Page 1A-22 for installation information
Answer: Yes WST offers a (6) optional switch option for this application with 329-071 see page 1A-12
Answer: Yes tying into the Neutral Safety switch circuit (located in the front wall PDM P 1A-4) with a signal controlled relay will stop the truck from starting. the starting schematics can be found in Mod 156and are specific for each engine Make.
Does the 4700 model have the same electrical architecture as the 4800/4900 models?
Can you deactivate the brake override circuit so that the 4-way flashers stay on when the brakes are activated
I have installed aftermarket LED tail lamps to my vehicle but they are not working properly
does WST offer switches that are ignition controlled that are not rated to 20 amps or relay controlled
If I need to stop the truck from starting under specific conditions is there a way I can do this
Question: How can I tell from the order if the truck has any body builder connections?Answer: look at sales code 334 and 353 to determine if supplemental body builder harness options where ordered with your truck.
If there is a Body Builder option, what type of interface plug does the option have and where will it be located?
The 4700 offers blunt cut wires at the BOC with an access plate in the floor for body builder connections see page 1A-10/11 and 1B-23/24. The 4800/4900/6900 offer
builder harnesses to the exterior BOC and the End of Frame with std plugs. for schematics and details.
Where can I find specific transmission information on the truck order and in the Body builder book?
Truck specific Transmission specifications can be located in the truck order under sales code 342 and schematic information can be found using the sales codes
of this chapter of the body builder book
Can you obtain wiring diagrams for specific options for serial numbers and any information on dealer optionally installed features?
Specific schematic information can be obtained by serial number is available to our dealers on line via PartsPro and EZ wiring. Use page 1B-2 of this chapter to locate the module location information.
Does Western Star utilize the (J1939) CAN-bus data protocol?The Western Star dash gauges and driver display (if equipped) are controlled
via the J1587 data bus. See the star gauge P 1A-7, 1A-8 for more information

Answer: Yes some trucks will be equipped with a capped plug at the bac of cab LH rail that is labeled supplemental trailer cable wiring (shown on P 1b-13) if the 388 Mod option has ordered. If this option and plug is not in the harness Pins #20,33,44,57 and 71 can be
accessed in the Main Chassis Bulkhead. The pinout details for this plugcan be found on page 1B-3 in this chapter

Chassis Harness Max Complexity Harness
New electrical systems for 2010 will be shown using a Max Complexityharness layout L06-82534. This new diagram system provides all possible connections that are available on one single diagram. This informationprovides the connector part number and the Sales Code and or Module numberthat the option and schematic detail can be found.
How to use this diagram system
* Use the diagram to locate where on the chassis the connections will be located Note: some locations are approximate due to wheelbase differences
* Not all connections shown in the diagram will be on any one specific vehicle
Note:To order new harnesses for service or repair refer to Parts Bulletin 54-018

Remote Fast Idle Circuits:
- Wires 440D, 440F & 440E are spliced into the cruise switch wiring in the dash and run though the front wall at a 40 pin connector pins 11, 9 & 10 respectively.
- Harness P/N A06-74578-000 ties into the 40 pin connector on the engine side of the front wall and ends in a 6 pin connector with wires 440D, 440F, 440E & 440G. (This harness is approximately 51" long.)
- Harness WWS 87208-3428-210 connector PS19_0 will connect to the 6 pin connector and have enough length to route to the end of frame, i.e. this harness is 210" long.
