If I need a Knock Sensor Control Unit, (the computer box, not the actual probe thingy) then doesn't the PL (16v) AND the 2H use the same box? Both are doing the same job right? Just trying to expand my possible parts pool out there. Thanks, Ken 1979 Scirocco "McFly" 16v conversion - Engine in, now the hard part Electrical : ( VORTEX: "Indiana Red"
