For 1990-2009 cars

### Removal Procedure

1. Turn the ignition OFF.
2. Remove the air induction resonator.

Important: Note which spark plug wire is removed from which coil tower. The spark plug wires must be connected to the correct coil towers.

3. Remove the 2 upper electronic ignition (EI) module bolts.
4. Using a small, flat-bladed screwdriver, remove the spark plug wires from the coil tower by gently prying between the EI module and the black connector position assurance (CPA) housing.
5. Disconnect the EI module harness connector.
6. Remove the 2 lower EI module bolts.

### Installation Procedure

Notice: Refer to Fastener Notice in the Preface section.

Notice: Verify the threads of the bolts, mounting surface, and thread holes are clean and free of any residue.

Use care when installing the EI module bolts. Make sure the bolt head is seated on the EI module when the torque specification is reached. If the bolt head is not seated on the ignition module, remove the bolt and tap the hole to clean any debris from the threads. Over torquing of the EI module will result in cracking the coil housing and damaging the coil.
1. Install the EI module and the lower two bolts.

Tighten
Tighten the EI module bolts to 8 N·m (71 lb in).

2. Connect the EI module harness connector. Push in connector until a click is heard and pull back to confirm a positive engagement.
3. Insert the plug wires into the CPAs. Connect the spark plug wires with CPAs to the coil towers.
4. Install the upper 2 EI module bolts.

Tighten
Tighten the EI module bolts to 8 N·m (71 lb in).

Important: Orientation of the wires to the EI module is critical to the operation of both the module and On-board diagnostics. The orientation from left to right is (4) (1) (2) (3).

5. Install the air induction resonator.
