I know exactly what you mean now since I have an '89 harness at home. I was thinking a later model truck too. I'm not sure if there are extra pin locations in the plugs between the engine harness and then back to the computer. I don't think mass air had been thought of in the trucks at that point. If you can find a mustang injector harness, it will have two 10 pin plugs on it that I want to say are the same as those four round ones on your truck harness now. Maybe you could add one and get the functions that you need and still make it look stock.

I believe there are extra pin locations, though not necesarily on the same connector. Might be two extra's on two of them, one here, one there, etc. Remember that injector one and two wires are already run, as are the power feeds. So that's three of nine wires already done. He only needs six.
Me, being lazy, I'd just snip off a weatherpack connector with 10 or more thick-gauge wires on both sides of the connector and wire a 5th connector, and leave the old stuff where it is. Much easier to troubleshoot when everything is together, I think.
Later year F- and E-series would have these (v8), as would any of the full size ford from 92/93 or so on. Crown Vic, Town car, Marquis and the MN12 V8 series... Thunderbird, Cougar, Mark VIII, and of course Mustangs. I suggested other vehicles because at least around here, finding an intact V8 mustang-anything is difficult (in NJ).
Parts are parts, so you can leech a suitable connector off GM, Chrysler, etc. As long as you have both halves, and it has at least 10 thick wires, and came from under the hood (thus weatherproof), you're good to go. GM connectors are especially nice because pin holes that aren't used aren't cast close like Ford. What they do is shove in a rubber thing to plug the hole, which is easily removed with needlenose pliars. Two mating pairs from two common-as-dirt FWD junkyard cars would be perfect. You'd have six thick-gauge wires in each, simply dismantle both pairs, move all the thick wires over to one, and reassemble without any special tools.
