A standard KKL cable will work for reading engine ECU. You only need to other cables to read ABS and Airbag. You can mod the KKL to read them all. I bought one but unfortuantly the car has a problem and I cannot get access to the ECU. The lead works fine on ABS/Airbag/ECU on multipla once modded. Just wish it would work on my dads car.
Ill have to get my backside into gear and have a look into the wiring to see why I cannot access the ECU. Probly dodgey wiring or corrosion in the ECU plug.
