Section I. WIRING HARNESS AND CABLE REPAIR
SCOPE
This section contains instructions on repair of wiring harnesses and cables (leads). Repair
of wiring harnesses and cables consists of replacement of defective connectors, shells, and
terminals, or taping cut or worn insulation and exposed wire conductors. Pages 3-2 through 3-5
show exploded views of typical harness and cable connectors used on the vehicle and give
procedures for disassembly and assembly of connectors. When soldering is required, procedures
in TB SIG 222 must be followed. If multiple pin connectors are disassembled, tag or label all wires
and cables to ensure that correct connections are made at time of assembly.
The following procedures are contained in this section:
