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-B.

J 38125-B Terminal Repair kit
Important: Refer to Wiring Repairs in order to determine the correct wire size for the circuit being repaired. Using the correct wire size ensures that
circuit integrity is not compromised.
If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gauge size (0.5 mm, 0.8 mm, 1.0 mm, etc.).
Use the sealed splices and splice crimping tool from the J 38125-B. Use the following wiring repair procedures to ensure the integrity of the sealed
splice.
Crimp And Seal Splice Table
Important: Perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged.
1. Open the harness by removing any tape.
To avoid wire insulation damage use a sewing seam ripper (available from sewing supply stores) to cut open the harness.
2. Cut the wire.
-
Cut as little wire OFF the harness as possible. The extra length of wire may be needed to change the location of a splice.
-
Ensure that each splice is at least 40 mm (1.5 in) away from other splices,harness branches and connectors. This helps prevent moisture from
bridging adjacent splices and causing damage.
3. Select the proper size and type of wire.
-
The wire must be of equal or greater size than the original.
-
To find the correct wire size do one of the following:
-
Find the wire on the schematic and convert the metric size to the equivalent AWG size.
-
Use an AWG wire gauge.
-
If unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation.
-
The wire's insulation must have the same or higher temperature rating.
-
Use general purpose insulation for areas that are not subject to high temperatures.
-
Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected.
Important: Use Cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC.
Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact.
4. Strip the insulation.
-
Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced.
-
Be careful to avoid nicking or cutting any of the strands. Check the stripped wire for nicks or cut strands.
Important: If the wire is damaged repeat this procedure after removing the damaged section.
5. Select the proper sealed splice sleeve and crimp tool nest according to wire size. See the above table for color coding of the splice sleeves and the
crimp tool nests.
-
Use the crimp and sealed splice sleeves on all types of insulation except tefzel and coaxial.
-
Do not use the crimp and sealed splice sleeve to or from a splice with more than two wires coming together.
6. Position the splice sleeve.
-
J 38125-B to position the splice sleeve in the proper color nest of the Splice Crimp Tool.
-
Place the splice sleeve in the nest so that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop 3.in the
middle of the barrel (2) to prevent the wire (1) from going further. Close the hand crimper handles slightly to hold the splice sleeve firmly in
the proper nest.
7. Insert wires Into splice sleeve and crimp.
