One test I
thought of last night while trying to get to sleep is to disconnect
the
plug on the column and see if the blue wire is grounded .

A word of caution, pretty sure the control for the torque converter
lockup goes to a solenoid in the transmission. So it will show a
very
low ohm value that looks like a short circuit to a meter. It should
draw about 0.5 amps when working.


That would be around 24 Ohms, which should show clearly on a decent
digital meter. Subtract out the reading with the probes shorted

Schematic "Power Side Control #3" indicates that pin D will short to
ground when the TCC Signal Switch operates. If the plug can be
rotated, could pin D have been misconnected to pin B that brings power
for the solenoid? The solenoid pin should show up as a low but not
zero resistance to the case.
