Ok...getting closer little by little....stuck on a few wiring issues,...the distributor has 2 plugs on it, one a 4 wire w/round posts, the other a 3 wire w/spade terminals......cant find what plugs into the 3-wire plug...any ideas what this goes to?? also, the wires from the temp sensors that WERE on the water neck on the manifold, since they arent on my new engine should I just tape them off and let them hang or should they be grounded for some reason ?.....
