says it was around the airbox/airflow meter in what i was reading about it.. maybe different locations for different models? wouldnt really matter either way if we know pin 30 on the ECU is the input from the sensor as its just a matter of running 1 wire to the ECU then 5v power and ground on the sensor.

just wired in the 4.7k resistor and 100nF capacitor into the MAP harness i tossed together so just need time/better weather and ill stick it back in and see if i have any better luck with it. if i can get a stable idle and no fluctuation when holding the throttle a little open then i should be able to move on to the point of driving/tuning.
