94 F150 engine computer wiring harness interchange help needed

Hello everyone
What i have is a 94 F150 4X4 with the 4.9 L with an AOD trans and yes it is a aod trans,i put it in.
The old 6 cyl engine with about 300k has had a lower end knock for 2 years so i am getting ready to replace it.
I have a complete 92 low milage 4.9 that is ready to drop in and my question is can i use the engine computer harness that is still on the 92 engine? my engine computer harness is nasty in the truck.
Also (if) the 92 engine is bad i also have a real low milage 302 with 46k that has the harness on it also same square connector plus i have a spare v8 radiator,frame/engine mounts everything to do the v8 swap,,,no emission testing where i live. I looked it up on my ADP Hollander E-Book and it does not list that harness for some reason,

Thanks in advance
Dan

There is no guarantee the harnesses portions are pinned the same.. in both cases, so you're gonna have to trace the wires to know for sure. And wiring colors would have changed from year to year as well so that's not going to help you either.
