REPAIR

This section contains instructions for repair of wiring harnesses and wires (leads). Repair of

wiring harnesses and wires consists of replacement of defective connectors, shells, and terminal, or

taping cut or worn insulation and exposed wire conductors. Pages 3-12 thru 3-17 show exploded

views of typical harness and wire 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 to ensure

correct connections are made at time of assembly.

The following procedures are contained in this section:
