Ok, I'm stuck my cars new engine is ready to run just its waiting on a wire harness. I have a new ecu thats for the motor and thats it. my old motor was a D15B2 dpfi and my new motor the D15B7 is mpfi and i cannot find out out to get my car running because of this. as of right now i only have 80 cash and wont be getting any any time soon. so my only plan was to go find a D15B7 at the junk yard and pull the wires from the ecu all the way up to the motor and take them home and connect them to my new ecu and to all the sensor on the motor. is it as easy as that or is their more? someone explain plzzzz. im stuck.
