Harness, Oxygen Sensor Overlay

NOTE: Prior to replacing any parts, (Oxygen Sensors, Oxygen Sensor Module,
Transmission Wiring Harness or PCM) perform the Repair Procedure below
and also perform an Oxygen Sensor Verification test drive also described
below.
NOTE: Vehicles experiencing P013A, P013B, P014C or P014D DTC’s must have the
Aftertreatment Validation Test (Section 4D of the Diesel Diagnostic
Worksheet) performed to ensure excess soot is not causing the DTC(s). IF
excess soot is found during Aftertreatment Validation Test, perform
appropriate repairs to eliminate soot accumulation. The repair procedure
below should be performed regardless of outcome or repairs performed for
other issues.

REPAIR PROCEDURE:
The Oxygen Sensor harness, (connecting the Oxygen Sensor Module to both of the
Oxygen Sensors) will now be serviced with an over-lay harness.
Please read through the entire REPAIR PROCEDURE before performing the repair.

Open hood.
Disconnect and isolate both negative battery cables.
Raise and support vehicle on a suitable hoist.
Position the overlay harness, p/n 68250763AA starting at the rear Oxygen Sensor
(tagged #2 on the overlay harness) following the existing harness loosely securing with
wire ties, (included). Pay close attention to the location designation of the Oxygen
Sensor connectors on the overlay harness. Do not secure too close to the Sensor or
the Module at this time. Extra length of the overlay harness can be taken up as a loop
between components.
Disconnect and cut the wires on the original vehicle harness at the vehicle side of the
connector near the rear Oxygen sensor.
Tape up the cut end of the convolute tubing and secure.
Clean (with shop air) the rear Oxygen Sensor connector and secure to the Overlay
Harness Oxygen Sensor connector ensuring lock tab snaps into place.
Disconnect and cut the wires on the original vehicle harness at the vehicle side of the
at the connector near the front Oxygen sensor.
Tape up the cut end of the convolute tubing and secure.
Clean (with shop air) the front Oxygen Sensor connector and secure to the Overlay
Harness Oxygen Sensor connector ensuring lock tab snaps into place.

NOTE: In the following steps, four of the terminals will be removed from the original
Oxygen Sensor Module connector and installed in the 68250763AA overlay
harness Oxygen Sensor Module connector. Of those four terminals, some
MY11 trucks were built with tin terminals and should have been gold plating.
Three of the four terminals, (if required, determined below) will need to be
replaced with the gold plated terminals supplied in the 68250763AA kit.
NOTE: Do NOT cut the original Oxygen Sensor Module connector wiring until
instructed to do so.
11. Disconnect the original Oxygen Sensor Module Connector and remove the
protective tape and plastic shield on the connector.
12. Carefully cut the tape securing the convolute tubing to the wiring near the new Oxygen
Sensor Module connector and pull convolute tubing off wire bundle about 8” (203 MM)
from connector.
13. The four terminals that need to be removed from the original vehicle O2 Sensor
Module connector and installed in the overlay O2 Sensor Module connector are
terminals 3, 9, 10 and 11 as shown in (Fig. 1). Terminal 10 will always be gold plated.
Terminals 3, 9 and 11 will need to be inspected on MY 2011 vehicles for plating to
determine if new terminals are required.

1 - Terminal 10 - Always a Gold Plated Terminal
2 - Terminals 3, 9 and 11- Must be Inspected on Model Year 2011 For Gold Plating

14. To release the terminals from the original Oxygen Sensor Module connector; use a
narrow blade, flat screwdriver (3 mm wide max), and pry the white TPA (white cover
seen when looking in connector). Notice the travel of white TPA is only .2” (5 mm) or
until a “click” is heard. This is the release point of the TPA. The TPA is a device that
locks the release finger so that when seated, terminal will not and cannot be
disengaged, (Fig. 2) and (Fig. 3). Do not extend the TPA past .2” (5 mm) or the TPA
may be damaged.

NOTE: Terminal #10 is ALWAYS gold plated and is not required to be changed ON
ANY APPLICATION. Inspect terminal #10 to see what the gold terminals look
like for a reference when inspecting terminals #3, 9 & 11 in the following
steps.
15. Starting with terminal #10 (Fig. 4), push the wire into the connector from the back, and
while keeping the tool or drill at 90° angle to the face of the TPA, push the tool or drill
in until it releases the lock finger in the connector as shown in (Fig. 5). At this point the
wire should pull out the back. As the terminal is removed; note the orientation of the
terminal in the connector for ease of installation later.

NOTE: If necessary to do any splicing in the following steps, use ONLY the brass,
Mopar splice band 05073034AA (included in 68250763AA) and always CRIMP
AND SOLDER, per instructions below.
16. Remove the other three terminals (one at a time) to be replaced (connector terminal
numbers 3, 9 and 11), start with #3.
a. Insert either J-38125-217 (Kent Moore number) OR MX 150-MX150L / 63813-1500
(Molex) OR a fabricated tool, (consisting of a chamfered 1mm drill bit installed with
the cutting end of the drill in the handle of Miller Tool #8351), into TPA (module side
of connector) into the desired “service port” until resistance is felt. Push the wire into
the connector slightly, then push tool in to release the terminal.
b. For Model Year 2011 only; Inspect terminal end for gold plating, (compare to
terminal #10 previously inspected in Step #15). If plating of terminal is NOT gold,
replace the terminal pigtail c with gold plated terminals supplied in the kit, p/n
68250763AA by proceeding to Step 16 (d). Repeat this for terminals in cavities 9
and 11.
c. If terminals are gold already or the vehicle is a 2010 or 2012, proceed to Step #17.
d. If terminals are tin; cut terminal #3 wire near the Oxygen Sensor Module connector
on the overlay harness.
e. Slide heat shrink tube on wire prior to splicing. Strip insulation on each wire and
crimp together using BRASS band clamp BEFORE SOLDERING using Mopar
splice band tool, p/n 05019912AA (or equivalent) then solder the crimped
connection and heat shrink each wire individually.
17. Working with the Overlay Harness Oxygen Sensor Module connector; use a narrow
blade, flat screwdriver (3 mm wide max), and pry the white TPA (white cover seen
when looking in connector). Notice the travel of white TPA is only 5 mm or until a
“click” is heard. This is the release point of the TPA. The TPA is a device that locks the
release finger so that when seated, terminal will not and cannot be disengaged,(Fig. 2)
and (Fig. 3) above.
18. Install the terminals into the connector through the insulator noting proper orientation
of terminal as noted in Step #15 above.
19. Repeat Steps 16d and 16e for the remaining two terminals (#9 & #11) making splices
in a staggered manner, to eliminate bulk in the harness.
20. Clean (with shop air) Oxygen Sensor Module connector and secure connector to the
module.
21. Cut the other remaining 12 wires from the original Module connector about 8” (203
MM) from connector.
22. Tape the wire bundle toward the connector, then Install and tape the plastic connector
shield to the connector body and install the removed convolute tubing adjacent to the
connector body with a continuous tape wrap joining the four wires from the vehicle
harness forming a “Y”.
23. Tape wires together then install and tape the removed convolute tubing adjacent to the
connector body.
24. Inspect and clean (with shop air) Oxygen Sensor Module connector terminals and
secure connector to the vehicle harness.
25. Secure all wiring with additional wire ties as necessary and tighten up loosely installed
wire ties and trim wire tie tails.
26. Lower vehicle, reconnect batteries.
27. Perform Verification below.

-9-

25-002-14

Verification:
Verification will ensure Oxygen Sensors are properly “relearned” and functioning as
desired.
1. Ensure PCM software is current. If software is not current, please update software
using appropriate Service Bulletin.
2. Connect WiTECH to vehicle if not already connected.
3. Operate the vehicle until warm and then drive the vehicle at 50 MPH. Perform a zero
fueling event (deceleration condition for 10 seconds, with foot off of accelerator pedal).
Repeat 3-5 times.
4. Monitor Oxygen Sensor percent in WiTECH, Data Display; percent should not vary
more than 4.0% from each other during any of the drive events. Variance of greater
than 4% will result in MIL illumination.
5. Further diagnosis will be required if variance is exceeded. Refer to TechCONNECT for
DTC(s) set during verification.
