Looks like this site doesn't get much activity. But, if someone reads this, I am doing a swap with a motor from a slightly older version and there are a couple of differences. My Broke one has a different wiring harness, for the EXTRA fuel injector hidden under the intake manifold, that is not on the Good, but older engine. Also, the flywheel on the Broke one has a "band" with a sensor (at the top of the bell housing). I guess I should use the intake manifold from the Broke one and the flywheel from the Broke one and try to put this together? Just looking for any advice.
