TPS means nothing without a PCM in the system. The TPS sends a variable voltage signal that only the PCM can use. The OD solenoid is wanting an on/off ground signal.
Hook a pressure gage into the governor test port. Find the pressure that it supplies for the speed you want OD to come in at. Then pickup a 1/8 NPT pressure switch for that PSI at a parts store. It will turn on/off the OD at the same speed every time.
Now going this way remember if your towing heavy you have no way to delay OD engagement. I would still put some type of over ride switch on OD. Maybe a switch on the throttle linkage that drops the power to the OD above 3/4 throttle
