Swapped the ECM's. No longer in limp mode. Engine runs great, and the RPM issue is gone. Seems the manual ECM keeps the RPM's up higher (1100)as the clutch is engaged for a few seconds before it drops to idle RPM's (600). No more flashing O/D light.
I do not have a working speedo with just the ECM swap. I decided to swap the Ranger (2wd) man trans harness out for the 95 EX man trans harness. The main harness connectors do not mate. The auto and manual connectors are opposite of each other as far as the plastic connectors are made. The slots & tabs are 180* of each other. Why the 95 Ranger trans harness mates, I haven't a clue.
So it is either swap the engine harness for a working speedo, or live without it. The only thing I can think of is that maybe when I spliced in the longer wires to extend the VSS pigtail, is that I screwed it up somehow. I only used crimp connectors as I didn't think low voltage would matter on that type of connection.
Just for future reference:
