nope, the wiring can't be used, need to have the M44 wiring.. further more all M44's have EWS.. you will also need the key and the internal wiring loom..
why do u need to conv?from m42 u can mod it to keep up like m44.for the money u spend on that its better u get a piggy back n swap the afm to the ones like the m44 using.that all u need to get like the stock m44.
