IMPORTANT: When the campaign has been completed, locate the base completion label in the appropriate location on the vehicle, and attach the gray completion sticker provided in the field service kit (Form WAR261). If
the vehicle does not have a base completion label, clean a spot on the appropriate location of the vehicle and
first 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.

PTO Feedback Circuit Inspection and Jumper Harness Installation
The jumper harness is necessary to complete the PTO switch feedback circuit so the indicator light on the dash
switch illuminates when the PTO is engaged. See Fig. 1.
IMPORTANT: The harness connector the jumper connects to may be positioned somewhere other than the location shown in Fig. 1. It can most likely be found on top of the transmission, or along the left-hand frame rail
near the bell housing. The harness connector will have to be located before routing it toward the PTO feedback
switch, then the new jumper will be installed.
NOTE: The jumper harness may not be missing on every vehicle contained in the campaign population.

1.

Check the base label (Form WAR259) for a completion sticker for SF663 (Form WAR261) indicating this
work has been done. The base label is usually located on the passenger door about 12 inches (30 cm)
below the door latch. If a sticker is present, no work is needed. If there is no sticker, proceed with the next
step.

2.

Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

3.

Check the PTO indicator light operation. Start the engine, make sure the park brake is set and the transmission is in neutral. Use the dash switch to engage the PTO. Observe whether or not the indicator light
on the dash switch illuminates solid. If the indicator light illuminates solid, this confirms that the jumper is
present.
NOTE: A flashing indicator light indicates that the request has been sent to engage the PTO, but does not
confirm engagement.
3.1

PTO Engages and PTO Indicator Light Illuminates solid:
No further action is required. Go to step 11, and use the inspection only SRT.

3.2

PTO Engages and PTO Indicator Light flashes:
This indicates the PTO feedback switch jumper is likely missing. Go to step 4, and inspect for presence of the PTO jumper.

3.3

PTO does not Engage and PTO Indicator Light flashes:
Inspect for the presence of the PTO feedback jumper at the transmission. See Fig. 1.
Is the PTO feedback jumper present?
YES → No further action is required. Go to step 11.
NO → Go to step 4.

IMPORTANT: If the PTO does not engage, any repairs to correct this condition are outside the scope of this
campaign.
NOTE: In some cases, there will be a label near the connector, as shown in Fig. 2, that reads ‘PTO Switch.’
The connector will contain circuits 200 (PURPLE) and GND (BLACK).
4.

Locate the connector that attaches to the PTO jumper. See Fig. 1 and Fig. 2.

NOTE: To aid in locating the connector that connects to the jumper, it may be helpful to view the harness that
contains it. The harness will either be in the BOM ID ‘80S’ or ‘885’ in EZWiring®.

5.

Is a print of the harness from EZWiring needed to locate the harness connector?
YES → Go to step 6.
NO → Go to step 8.

6.

Go to EZWiring.
NOTE: If there is no 80S BOM ID, look instead for the 885 BOM ID.
6.1

Enter the vehicle serial number and hit enter to populate the VIN. Next, select “All Harnesses” in the
‘System Options’ drop down, then click the ‘View’ button. See Fig. 3.

7.

Select the harness in the 80S BOM ID (or 885 if there is no 80S BOM ID). The desired harness will typically have “ENG” in the description. Click the hyperlinked harness part number to view the harness print.
See Fig. 5 .

8.

Once the connector is located, separate the branch of harness containing the connector if necessary, and
route it toward the PTO feedback switch. See Fig. 1. Secure the harness with zip ties as needed.

9.

Connect one end of the new jumper (A06-93462-000) to the harness, and then the other end to the PTO
feedback switch on the PTO. See Fig. 1.

10.

Verify the operation by starting the engine, and engaging the PTO. If the PTO indicator light on the dash
switch illuminates, this confirms the installation is successful.

11.

Clean a spot on the base label (Form WAR259) and attach a campaign completion sticker for SF663
(Form WAR261), indicating this work has been completed.
