1.dicconect the connector (A) from the ecu.
2.detach the plastic cover on that connector (you should now be able to to see the wires that 'enter' into the connector.)
3.mark that on the position 20 is a empty hole.
4.put a wire into that hole,it is recommended you use a wire like the others (that has a small socket at the end.)
5.the other end of the wire,connect it to ground (or the [-] terminal from the car's battery.)
6.connect the connector back onto the ecu
7.read/write the software via obd
8.disconnect the wire from the battery when finished (otherwise the car won't start.)
9.enjoy the ride.
Once you have connected the wire from pin 20 to negative,turn on the ignition to mar,a key light should come on the dash cluster,that means the car is in boot mode,now you can read and write the ecu,make sure you follow the steps above,i hope this helps a few people out (kwp2000+ and galletto 1260)
