i searched but either i typed in the wrong stuff or i idk i should get and install my st205 ecu this week but im worried ill get the check engine light for not having the intercooler pump. can someone tell me or show me a link on how to avoid the cel and yes i already know a gen3 MR2 ecu would be one way to avoid this thank you. Btw I'm using the jumper harness from berk technology

find the wiring diagrams.
look to see if it controls a relay or the pump directly.
substitute resistor of suitable value to make ECU think the electrical load of the IC pump is there.
