What year did the crank angle sensors change?
Couldn't tell you, cant even tell you if the actual sensors have changed (I have a feeling the PN's have..), but the wiring setup is slightly different between the years. i.e later models are standalone plug, where as 01 it was in a little harness with the oil pressure sender. Worst comes to worst, I'll just re-plug em if they don't plug in out the box.
Not a great deal to report.
I've actually got a specific polishing machine waiting for me at home as a b-day present.
