3. Prepare the splice. Untwist the conductors and
follow the splicing instructions for copper wire.
Staggering the splices by 65 mm is recommended.

4. Re-assemble the cable.
• Rewrap the conductors with the mylar tape.
• Use caution not to wrap the drain wire in
the tape (1 }.

• Follow the splicing instructions for copper wire
and splice the drain wire. ,
• Wrap the drain wire around the conductors
and tape with mylar tape.
Important: Apply the mylar tape with the aluminum
side inward. This ensures good electrical contact with
the drain wire.

5. Tape over the entire cable. Use a winding motion
when you apply the tape.
Splicing lnline H(uness 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 following
procedure.
1 . Open the harness.
• If the harness is taped, rernove the tape.
• To avoid wiring ins4lation damage, use
a sewing ripper in order to cut open the
harness.
• If the hamess has a black plai,tic conduit, pull
out the diode.
2. If the diode is taped to the harness, remove all of·
the tape.
3. Check arid record the current flow direction and
orientation of diode.
4. Re.move .the inoperative diode from the harness
with a suitable soldering tool.
Important: If the diode is located next to a connector
terminal remove the terminal(s} from the connector
to prevent damage from the soldering tool.
5. Carefully strip away a section of insulation next to
the old soldes:ed portion of the wire(s}. Do not
remove any more than is needed. to attach the
new diode. ·
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.
