ANyone have any idea what the diferences in the 06 and 07 would be and if this harness will work?( other than one is drive by wire and the harness is drive by cable) ...lots of mindless questions guys... and I thank you in advance..
The LQ9 is iron block Gen III
The L76 is AL block Gen IV
So sounds to be like you have the Gen III LQ9 by the harness. So you will need a Gen III PCM.
