OFF-HIGHWAY TRUCK	THIS TIB REPLACES THE APRIL 2, 2003 OFF-HIGHWAY TRUCK TIB, COMPONENT CODE 50501. DESTROY THE APRIL 2, 2003 TIB. 797 (5YW1-UP) 797B (JSM1-UP)
	Component Code: 5051

SUBJECT: Hoist Control Valve Electrical Connectors May Get Matched Incorrectly

PROBLEM:

The 155-0382 Hoist Control Valve Group contains several electronic actuator groups in a relatively small area. All connectors are 2-pin DT connectors and are on a common breakout from the main harness. When the hoist control valve is installed, repaired or replaced, it may be possible to incorrectly match the connectors of the mating 220-5617 Harness Assembly (797B), or 193-4669 Harness Assembly (797A).

SOLUTION:

Use the following illustration to properly connect the hoist control valve to the main harness.
