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 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.
SIR/SRS System Wire Splice Repair
Apply a new splice (not sealed) from the J 38125 if damage occurs to any of the original equipment splices (3 wires or more) in the SIR/SRS wiring
harness. Carefully follow the instructions included in the kit for proper splice clip application.
CONNECTOR POSITION ASSURANCE (CPA)
The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of all the SIR/SRS system electrical connectors. 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 SIR/SRS
mating terminals.
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
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
Tools Required
J 38125 Terminal Repair Kit
1. Open the harness.
-
If the harness is taped, remove the tape.
-
To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness.
-
If the harness has a black plastic conduit, pull out the desired wire.
2. Cut the wire.
-
Cut as little wire off the harness as possible.
-
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
