I figured it out and it works beautifully! Hotter, less smoke, starts in 15 degree weather (coldest tested)!

The connections are all found underneath the steering column. I just took the little aluminum pins from some spare part and individualy wired them and inserted them into the old harnes. Viola!

It worked great!

I can't beleive how much better it starts. Perhaps new loop style plugs would have helped as well, but I like the fast glow.

I recommend the switch. Cost $92 (inc shipping) from fastlane.
