Location of new control harness assembly and bracket on C7 and C9 engines (1) 373-2790 Bracket (2) 373-2789 Control Harness As |
Illustration 2 | g02589236 |
Location of new control harness assembly on C32 engines (3) 375-2791 Control Harness As |
The new 373-2789 Control Harness As replaces the current 281-9195 Control Harness As on C7 and C9 engines. Also, the 373-2790 Bracket must be replaced, if a new control harness is ordered for C7 and C9 engines. The new 375-2791 Control Harness As replaces the current 281-9195 Control Harness As on the C32 engines. The harness is adaptable back to the first production of the engine.
The change is effective at the factory with the serial numbers that are listed in Table 1.
