do anybody have a pr4 ecu pinout diagram...the owner before had a b16 in it..i have a pr3 diagram and everything is the same except the pin #B5 and B19...the car is a 91 integra...i just need to know what the two pin # goes to because i'm putting a 95 B18c3 in... I think there is a wire missing too... The B19 has an extra wire that was cut to put in the knock senser but the wire to B5 is missing..
