Gray locking wedge removed from ECM connector
Remove gray locking wedge from 86-pin connector to provide access to release the DT Pins.Note: Circuit U937 to be removed from pin location number 24 and transferred to pin location 73.Note: Cloth tape will need to be removed to the split in the harness main bundle.Note: The U937 wire can then be routed into the opposite branch to gain enough free length to make the connection.Note: The U939 wire removed from pin location 73 has adequate length to be loaded into location 16.
Transfer and relocate the wires as detailed in Table 2.
Reinstall the locking wedge (B) when all wires have been transferred and relocated.
