Note: The injector trim code (11) will be used later if the injectors have been changed. Write down injector trim code (11) which is located on the solenoid.
When a fuel injector group is serviced, the new fuel injector group's electronic injector code must be programmed into the engine's personality module software by using the calibration menu on the Electronic Service Tool. If the new fuel injector group's electronic code is not entered, the previous fuel injector group's characteristics are assumed.If it is not possible to immediately reprogram the electronic injector code of the injector into the personality module software, the engine will not be severely harmed. The new electronic injector code should be reprogrammed as quickly as possible in order to optimize engine performance.

Install electronic unit injector (3) into the original location in the cylinder head.
Install hold-down clamp (7) .
Do not reuse the injector hold down bolts. New injector hold down bolts must be used.
If the injector hold down bolt is loose during the removal procedure, inspect the injector bore for wear and debris. Replace the clamp and spacer.
Note: Use new bolt (5) .
Install spacer assembly (6) and bolt (5) that holds the electronic unit injector in place.
Pull the electronic unit injector completely into the bore. Tighten the bolt according to the following procedure.
Tighten the bolt for the electronic unit injector to 30 7 N m (22 5 lb ft).
Loosen the bolt until you can turn the bolt by hand.
Tighten the bolt for the electronic unit injector again to 30 7 N m (22 5 lb ft).
Install harness assembly (2) on electronic unit injector (3) . Tighten the nuts to a torque of 2.5 0.25 N m (22 2 lb in).
Install bridge assemblies (4) onto the valve stems.
