Your 86 F Bird is wired with a MAF sensor, the 16198259 is the correct ECM for that system. Unless someone radically changed the wiring , it should be plug in and play.
That was the point that I was trying to elude to about the difference in the ECM s . They look the same , but not all pins or terminals at the plug ins are used, depending on the type of FI system that it was designed to run.
The circuitry inside the ECM ( hardware) is different, and each one has a different wiring harness to hook to necessary devices under the hood.
As long as the underhood wire harness is intact, plug it in and go.
The #62 ECM has nothing inside that hooks to the terminals where the MAF sensor wires go in the ECM connector , because it doesnt use one. The ECM doesnt have the hardware inside to run it.
