wiring harness woes

Ok guys I got to going over my parts for my 5.0 swap and I noticed something. Im missing part of my wiring harness. Who can tell me what the three round plugs are for? it looks like one is grey and 2 are black or dark brownish in color. One is by the Mass Airflow meter plug and the other 2 are by the EEC test plug. Would I be correct in assuming that any harness with these plugs on it has the wires running to the same sensors and such since ford did actually use the same type sensors in SEFI cars?

For one what is your harness out of? An 87 5.0 bird?

the ones by the eec test plug are for connecting to the dash harness.

The one by the general location of the maf (if you've converted this harness) would be for the WOT relay.

oh yeah good point its out of a 90's stang
no clue but I dont see an alternator plug on this could that be one of them? not sure this might be a piece of info that is more like well DUH but its also SEFI injection I looked on the ford fuel injection website and it says one is for the TFI isnt that the distributor or coil? I have the plugs for both of those on the harness as well as all the sensors on the engine that I can see its just those three plugs I cant figure out what go to doesnt help its not in a car its laying in my dining room floor.
