The '7060 was used with the 4L80E, not the 4L60E. There's also no non-automatic harness for the '7060. In those years if the truck was manual it would have had a '7747.

You need to finish the connections at the dizzy. The ICM is what triggers the ECM for engine speed info through the purple/white wire from the module. The ICM needs to have 12V connected on the pink wire, the white wire that is paired with the pink wire is what triggers the coil.

So basically, the ICM functioning is of paramount importance to the PCM doing its job.

You will also need to make a number of changes to the BIN file to make it work with a non electronic automatic, since they never came that way.

The 16197427 would have likely been a better choice here since there plenty of info about using them with manuals and non-electronic auto transmissions.
