Around that time Ford was way behind everyone else when it came to viewing live data and retrieving fault codes. I had some of the nicest equipment, but on those, all I could get was fault code numbers, and it took a special sequence of procedures and five to ten minutes to do what you could do on a Chrysler product in less than 15 seconds.
You're better off fashioning an indicator light that you can connect to the test socket. How to do that is shown in the service manual. If you can't find that, I'll see if I can dig up an old manual at home for the instructions. Ford came out with a rather archaic tool, but it was obsolete after just one year so you won't find them at any dealerships.
Look at the production date on the door sticker. If it's late in the year, you may have an early production '87 model. There is no reference to a diagnostic connector or fuel injection for '86 models that I can find on the online service manuals. For the '87 wiring diagrams, they don't show the connector. They only show wires with designations that they "go to the diagnostic connector". You're just supposed to know which one is which by their colors, I guess. I found a white. Red wire that goes to the Engine Computer. There's going to be a ground wire and a 12 volt power supply wire in that connector too. I DO remember that the single pigtail wire goes to the fuel pump.
