Installation Instructions for: EMS P/N 30-1312 2000-03 2.4L M/T Mitsubishi

Removing the Stock Engine Control Unit
a) Access the stock Engine Control Unit (ECU). The location of the ECU on both the Eclipse and Lancer is behind the glove compartment mounted vertically on the firewall.
b) Carefully disconnect the wiring harness from the ECU. Avoid excessive stress or pulling on the wires, as this may damage the wiring harness. Some factory ECU’s use a bolt to retain the factory connectors, and it must be removed before the harness can be disconnected. There may be more than one connector, and they must all be removed without damage to work properly with the AEM ECU. Do not cut any of the wires in the factory wiring harness to remove them.

Ford Pats (Passive Anti Theft System) Initialization With The 2534 Global Programmer

There are five types of PATS implementations from Ford (A, B, C, D, E). Refer to Table 1 (page 11) to identify what type of PATS your vehicle is equipped with. PATS initialization is generally performed after programming.
The A or D version of PATS does not store the key information in the PCM, therefore NO PATS KEY RELEARN IS REQUIRED after programming.
The B or C versions of PATS store the key information within the PCM and MUST be transferred to the new PCM, or relearned on the vehicle after the new PCM is installed.
