im using the m20 harness with the m30 ecu. and should be a pretty easy plug and play right?

from what i understand I think you lengthen the 1st injector wire and the wires for the coolant temp sensor. Maybe its both the coolant temp sensor and the temperature switch. On my m30b34 they are in a row on the water housing for the thermostat. The two sensors that is.
