plug and play not working

Well Dave your crystal ball is working much better than mine.

WHAT IS THE YELLOW and what else is hooked to "whatever that is?"

You say "neg side of the coil?" The neg side of the coil is NOT ground!!!!

The black from the distributor hooks to the neg side of the coil. Look at the damn diagram. It does not say to ground the black.............the coil neg, does it? No.
