I'm digging into several issues that my SC has and remembered I had the HUGE EEC-IV supplemental documentation. I was skimming it and found 4 pages that I think are particularly helpful - especially for those savvy enough to tear down an IRCM for board level repair. I believe the schematic on page 3A-63 should be of assistance. I don't recall seeing this anywhere on the site. Perhaps I'm lucky that the sale of my car came with the OBD-I and OBD-II supplemental books for ALL 1994 Ford vehicles?
