REMOVAL & INSTALLATION
The engine controller is the computer/microprocessor that regulates all ignition functions. All other models (1989-96) employ a 60-way connector. The 1989 models (only) employ an additional 14-way connector. In most cases, the engine controller is mounted in the engine bay to the firewall or a fender. Some early models mount the engine controller in an air duct mounted on the inside left fender. Access to these units hidden in the air duct requires some dismantling of the air duct to get to them.
- Disconnect the negative battery cable.
- Remove the air cleaner duct from the controller, if equipped.
- Remove the three module retaining screws.
- Remove the 14-way (1989 models) and 60-way connectors from the controller.
Check the 14-way and 60-way connectors for damaged or bent pins (and correct if any are found) prior to plugging it in.
- Connect the 14-way (1989 models) and 60-way connectors to the controller.
- Install and tighten the module retaining screws.
