My problem is the 2008 chevy trailblazer 4.2 has a 3-wire crank sensor and the reluctor ring on the crank looks similar to a bicycle sprocket.
While I did not look at the reluctor ring on the 2005 4.2 engine we installed (which I assume is different) it had a 2-wire sensor.
So either I need to find a 3-wire that would work off a 2-wire reluctor ring or find a way to wire the 2 wire sensor into the 3 wire system.
Any help is appreciated, thanks!
