8. Reinstall terminal(s) into the connector body if
previously removed
9. Tape the diode to the harness or connector using
electrical tape.
Important: To prevent shorts to ground and water
intrusion, completely cover all exposed wire and diode
attachment points with tape.
H02S Wiring Repairs
Notice: Do not solder repairs under any circumstances
as this could result in the air reference being
obstructed.
If the heated oxygen sensor pigtail wiring, connector,
or terminal is damaged the entire oxygen sensor
assembly must be replaced. Do not attempt to repair
the wiring, connector, or terminals. In order for the
sensor to function properly it must have a clean
air reference. This clean air reference is obtained by
way of the oxygen sensor signal .and heater wires. Any
attempt to repair the wires, connectors or terminals
could result in the obstruction of the air reference and
degrade oxygen sensor performance.
The following guidelines should be used when
servicing the heated oxygen sensor:
• Do not apply contact cleaner or other materials to
the sensor or vehicle harness connectors. These
materials may get 'into the sensor, causing
poor performance. Also, the sensor pigtail and
harness wires must not be damaged in such a way
that the wires inside are exposed. This could
provide a path for foreign materials to enter the
sensor and cause performance problems.
• Neither the sensor nor vehicle lead wires should
be bent sharply or kinked. Sharp bends, kinks,
etc., could block the reference air path through the
lead wire.
• Do not remove or defeat the oxygen sensor
ground wire (where applicable). Vehicles
that utilize the ground wire sensor may rely on
this ground as the only ground contact to
the sensor. Removal of the ground wire will also
cause poor engine performance.
• To prevent damage due to water intrusion, be
sure that the peripheral seal remains intact on the
vehicle harness connector.
The engine harness may be repaired using the
J 38125-8.

SIR Wiring Repairs
The supplemental inflatable restraint (SIR) system
requires special wiring repair procedures due to
the sensitive nature of the circuitry. Follow the specific
procedures and instructions when working with the
SIR system wiring, and the wiring components (such
as connectors and terminals).
Important: Do not use the terminals in the kit in order
to replace damaged SIR system terminals unless
specifically indicated by the terminal· package.
Tools Required
J 38125-8 Terminal Repair Kit
The tool kit J 38125-8 contains the following items:
• Special sealed splices - in order to repair the
SIR system wiring
• A wire stripping tool
• A special crimping tool
• A heat torch
• An instruction manual
The sealed splices have the following 2 critical
features:
• A special heat shrink sleeve environmentally seals
the splice. The heat shrink sleeve contains a
sealing adhesive inside.
• A cross hatched (knurled) core crimp provides
necessary contact integrity for the sensitive,
low energy circuits.
The J 38125-8 also serves as a generic terminal
repair kit. The kit contains the following items:
• A large sampling of common GM electrical
terminals
• The correct tools in order to attach the terminals
to the wires
• The correct tools in order to remove the terminals
from the connectors
SIR Connector (Plastic Body and Terminal
Metal Pin) Repair
Use the connector repair assembly packs in order to
repair the damaged SIR wire harness connectors
and the terminals .. Do not use the connector repair
assembly pack in order to repair the pigtails. These kits
include an instruction sheet and the sealed splices.
Use the sealed splices in order to splice the new wires,
connectors, and terminals to the harness. The splice
crimping tool is color keyed in order to match the
splices from the J 38125-8. You must use the splice
crimping tool in order to apply these splices.
The terminals in the SIR system are made of a special
metal. This metal provides the necessary contact
integrity for the sensitive, low energy circuits. These
terminals are only available in the connector repair
assembly packs. Do not substitute any other terminals
for those in the assembly packs.
