Disconnect the computer harness connectors by releasing the locking tabs, or by unscrewing the retaining bolt. To disconnect the harness hold onto the plastic connector. Do not pull on the wires.
Remove all retaining hardware brackets from the old unit and reinstall them, if necessary onto the Remanufactured computer.
Reinstall the computer and secure the harness onto the computer. All harness connectors are keyed so they will only fit in the correct computer for that vehicle. If the harness connector doesn't slide on, check the key position on the harness and on the ECM to ensure proper application. Do not force the connector into the Remanufactured ECM.
Reinstall the negative battery cable and start the engine. It may be necessary to drive the vehicle for ten to twenty minutes before the Remanufactured computer will control the engine properly. This drive time will establish input readings and set the idle speed.
Pack the old computer in the original shipping carton for protection and return the used part to your supplier for core credit.
