Looking at an 8v for an engine swap from a 92 into a 93 Tracker.  It looks like there is extra emissions parts on the 92.  The EGR system has extra cooling lines and the distributor has a 3 wire connector instead of a 2 wire.  There is also a different plug coming off of the back of the throttle body.

Was there a California Emissions version of this motor that has different wiring?
