"There are many more, I don't have all of them electronically.

to get the correct one, you need a complete, accurate description; eg Merc 5.7L, 1998, MPI, Delco EST distributor, etc...

I think what you want is called the Fuel and Ignition System Harness Diagram.

You ccan also post on the mrecruiser board."
