Decided to put this in it's own thread...
Using information from this and this from radesignsproducts.com, I will try to document what you need to know to have manual control of yer A340 automatic transmission fer the T-100.
Looking at the EWD, the colors to the solenoids are:
A340 transmission (5VZFE)
Solenoid #1 = White
Solenoid #2 = Red-Yellow
Solenoid #3 (Lock-up) = Yellow-Black
A340 transmission (3RZFE)
Solenoid #1 = White
Solenoid #2 = Black-White
Solenoid #3 (Lock-up) = Yellow-Black
So tapping into the Yellow-Black wire will give you control of the torque converter solenoid. You could simulate the solenoid's resistance by terminating the ECU end with the proper resistor when you switch over to manual control. This should prevent the ECU throwing a check engine code fer the transmission.
Sending 12V to the lockup solenoid will activate the solenoid.
From the EWD, the solenoid resistance is about 13ohms.
Looking through the FSM and the EWD, there doesn't seem to be any splice points in the harness between the ECU and the lockup solenoid. This means you will need to tap into the wiring harness or build an plug/play adapter that would interface between the transmission's solenoid connection and the wiring harness if you don't want to cut into the harness.
A method to disconnect 12V power to the solenoid when the brakes are applied is an idea way to ensure the lockup solenoid is automatically disengaged. If not, yer gonna have to do this manually every time.
An indicator to show the lockup solenoid is in manual mode would be ideal, too.
