REPAIR INSTRUCTIONS, PART 1
1. Insert the unit injector portion of the harness
through the hole in the timing gear cover.
2. Connect the harness to each unit injector.
3. Connect the harness to the engine brake
control valve if installed.
4. Using high temperature wire ties, 983472,
attach the harness to the tie bar.
5. Carefully route the wiring harness over the
engine brake control valve. Position the
harness to the side of the boss at the top
of the valve assembly. Secure the harness to
the control valve and harness bracket in four
locations (see Figure 369).
Do NOT route the harness over the boss at the
top of the engine brake control valve. There is not
enough clearance between the control valve and
the cylinder head cover for the harness when the
cover is installed. The harness MUST BE
positioned to the side of the boss to avoid
damage to the harness.
