the wire from passing through the splice (3).
10. Close the handles of the J 38125-B until the crimper handles open when released. The crimper handles will not open until the proper amount of
pressure is applied to the splice sleeve.
11. Shrink the insulation around the splice.
Using the heat torch apply heat to the crimped area of the barrel.
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.
Splicing Inline Harness Diodes
Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the
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 diode.
2. If the diode is taped to the harness, remove all of the tape.
IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering
5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the
6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring
schematic to obtain the correct diode installation position.
7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the
diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment.
8. Reinstall terminal(s) into the connector body if previously removed.
IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape.
9. Tape the diode to the harness or connector using electrical tape.
Splicing Twisted or Shielded Cable
Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and
1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape.
