6E-8 EMISSION AND ELECTRICAL DIAGNOSIS
5. Solder
Apply 60/40 rosin core colder to the opening in the
back of the clip. Follow the manufacturer’s instruc-
tions for the solder equipment you are using.
6. Tape the Splice
Center and roll the splicing tape. The tape should
cover the entire splice. Roll on enough tape to du-
plicate the thickness of the insulation on the exist-
ing wires. Do not flag the tape. Flagged tape may
not provide enough insulation, and the flagged
ends will tangle with the other wires in the harness.
If the wire does not belong in a conduit or other har-
ness covering, tape the wire again. Use a winding
motion to cover the first piece of tape.
