Coolness. Thanks again.
I have the harness covered, I guess. I have the black 24 and 32 pin connectors in my stash. I found a pin-out for the 92 CPI engine in my 92 Light Truck Emissions and Drivability Helms manual. The only wire I have to add to the existing harness is the 4th gear signal, and remove all the 4L60e wires. Other than that, it's remove all the pins from the 7747 red and blue connectors, and sort and install them in the 2 black connectors. Not difficult, but tedious because of all the checking and double-checking the connections.
