I was wondering what i would need to do to get it hooked up with the h.o. firing order because i read its not pnp. I already have stock h.o. motor just wonder if i would have to re-pin my harness or would it be easier to buy a stinger harness and wire that to my factory body harness

Firing order is dictated by the cam and plug wire location on the distributor cap, then the ECU matches that when using sequential injection. The harness has nothing to do with ignition firing order.
I'd have to see a wiring diagram for an 85 F150 to say for sure (and I don't have one) but I'm almost positive it is plug and play if you run it in batch fire mode (since only Mustangs were sequential). If you want sequential you'd need to modify the injector wiring to match the Mustang.

I know to do a maf swap using a mustang computer a few pins need swaping but since its speed density i wasnt sure.. i guess ill just sit down with both diagrams and figure it out

Nothing "conventional" applies once you ditch Ford ECU's so what it takes to use a Ford ECU doesn't matter.
If you provide a diagram I can look it over, or you can do it, that's up to you. I'm betting the only stuff that's different than an A9L is stuff that we don't use anyway.
