Yes, You need a real bi-directional scanner to effectively deal with this project. What steps were taken to modify the change to manual trans vs the inhibitor/range unit from the
auto unit? It may be looking for the signal from that, I'm not sure how straight forward the clutch in sw. substitution for a signal is/isn't.

Yes I need a reliable way to know all the prerequisites are met for the starter relay to energize. I may even need a Door ajar Switch to be "closed" for all I know.

It just so happens that my automatic PCM's sensor circuit had issues. All the temp sensors, MAP, TPS and Pedal would all give a High voltage code. All the wiring's Ohm and volts checked out, so diagnostic procedures all pointed to the PCM. I took that opportunity to grab a 6 speed PCM($100 ebay) and that indeed fixed the sensor issues.

According to the service manual, the Clutch switch is just Normally Open that grounds out. My automatic harness didn't have a terminal populated in the PCM connector so I stole one from the Purge solenoid and grounded it out. Who knows if it really worked or not because i'm flying blind without a proper scan tool.
