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.
7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop.
8. Tightly close the handles of the crimp tool until the crimper handles open when released.
The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the
opposite end of the splice.
9. Using the heat torch, apply heat to the crimped area of the barrel.
10. Gradually move the heat barrel to the open end 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.

Splicing Copper Wire Using Splice Clips
Important: When making a splice in an area that may be exposed to moisture use a crimp and seal splice sleeve instead of a Splice Clip. Refer
to Splicing Copper Wire Using Splice Sleeves. See: Testing and Inspection/Component Tests and General Diagnostics
