Sierra 1500 2WD V8-5.3L VIN B HO (2006)
1. Open the harness by removing any tape:
-
Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage.
-
Use the duraseal splice sleeves on all types of insulation except tefzel and coaxial.
-
Do not use the crimp and duraseal splice sleeve to form a splice with more than 2 wires coming together.
IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must
obtain a clean strip with all of the wire strands intact.
2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice
locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors.
3. Strip the insulation:
-
When adding a length of wire to the existing harness, use the same size wire as the original wire.
-
Perform one of the following items in order to find the correct wire size:
-
Find the wire on the schematic and convert the metric size to the equivalent AWG size.
-
Use an AWG wire gage.
-
If you are 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.
-
Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced.
-
Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands.
-
If the wire is damaged, repeat this procedure after removing the damaged section.
4. Select the proper duraseal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color
coding of the duraseal splice sleeves and the crimp tool nests.
5. Use the Splice Crimp Tool from the J-38125 to crimp duraseal splice sleeve. In order to position the duraseal splice sleeve in the proper color nest
of the Splice Crimp Tool, refer to the table at the beginning of this repair procedure.
6. Place the duraseal splice sleeve in the nest. Ensure 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) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold
the duraseal splice sleeve in the proper nest.
