ISSUE:

^
If the harness cannot be repaired, replace the harness. Refer to Repair Operation 86.70.09 in the Sedan Range Repair Manual.

Wrap one 10" tie wrap (C-46294) around the bulkhead harness 2" to the right of the "W" bracket and around the bulkhead wiring that is routed
down along the side of the bracket.
^
