I will share my little experience with the PFC on my 1ZZ. What should have be a straight forward mod (with just a couple of wires to move) became a nightmare, the ABS light came on and is not working. My mechanic has gone through the wiring diagram and found that my 2002 Levin has different wirings to the pin out diagram. We had another 1ZZ with the PFC and plug my PFC to his car and the ABS was ok and once we compared the colour of the ecu wiring my car has all these light blue wires where the other Levin had normal colour wiring. Still haven’t resolved it yet but just want to get the car on the road first, so is getting tunned tomorrow and will sort out the ABS after.
