OK, guys all went well (well, a bit drama, but all fixed)
1) Car is back from mechanic today, end up spent $65 from justjap for a 180sx (SR20DET) throttle cable to fit on the greddy plenum..
2)Q45 AFM and TPS solved, got correct wiring, so if need help for the correct connection just ask..
3)the page 20 is talking about if R33 pre-95 model retain the throttle bracket position, other then that need to made one up..something like that..
cheers, all
