Nope sir, nasa ilalim ng dash board. I dont have a wiring diagram for my car so i have to trace all 200+pinouts ng ECU connector to look for the ACU pressure signal wire. Nung walang tumunog sa tester, dun ko nalaman may break sa wire somewhere at saka nag hanap hanap.. hehe..

3 wire sya sensor ang acu press. +5vdc reference, ground and signal fire going to ecu.
