it is used from a running 2003
Mitsubishi Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 3 months ago

unfortunately these computers are not plug and play units ,the keys needs programed to it

^2000 Models - When replacing the PCM, the Immobilizer ECU must always be replaced and the keys re-registered.

^2001 and Later Models - On all models except early production 2001 Eclipse Spyder (see note below), it is not necessary to replace the Immobilizer ECU when replacing the PCM, although all keys must be re-registered.

you will need a Mitsubishi capable scanner or equivalent to do the registration of the keys
