10. Start in the middle and gradually move the heat barrel to the open ends of the tubing:
*
The tubing will shrink completely as the heat is moved along the insulation.
*
A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.
Connector Position Assurance (CPA)
The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System
connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in
place in order to ensure good contact between the mating terminals of a connection.
Terminal Position Assurance (TPA)
The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely
seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Note: Use only DuraSeal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection.
Use DuraSeal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use DuraSeal splice sleeves where there are
special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using DuraSeal splice sleeves.
Note: 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.
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.
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 gauge.
-
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.
