I want to know....if there is a difference between the two obd2 of these two vehicles ek9 and ek 4...with different years? I believe that they have different on-board plugs. But I want to know if I will be needing a wire harness.....if a power FC that is for an ek9 (1998) will be installed into my 1999 b16 obd2? or it will plug in without any harness to buy?
thanks!
