EEC-IV pin 30 question

Overhauled my 5.0 ho and started to reconnect my efi harness back on to My 74 bronco. It's running a map system from an 88 stang 5.0. I did this conversion 10 years ago with the help from members of this site. I tried to tag everything I disconnected but long nights and to many beers caused me to forget a few. Question I have is on pin 30, I can't remember how to properly rewire it. My schematics show it goes to the neutral safety switch or ign. start. It also has a diode on it. Can you tell me how to reconnect it? Also does the ecm turn on the mil lamp by grounding it or supplying power to it? Thanks.
