After looking over the drawings in the tech manual yesterday, I think that the S/C clutch is in series with another component. Not just a ground & hot wire to the clutch. But I'm pretty sure that the S/C will not engauge in park, unless you have meter probe's stuck into both wire's . When the wife nailed it hard while I had the meter across the clutch wire's, it let out a big chirp and scared the crap out of me .
