The repair guide says it's an ECT and there is a an ECT solenoid in the diagram but not specifically a TC lock solenoid. I should look online at another site for a different wiring diagram or ask at a Toyota site. Why don't they set TC lockup at lower speeds and higher loads? My guess is engine knock under high load/low speed.

Thanks for the info. A brake switch is within my current skill set as opposed to a speed sensitive switch.I had also thought of a pressure sensitive throttle switch so it would lock up only under a certain load.

Now that I think about it , my fantastic digital vacuum gauge from Vtec-e, has two output signals which can be set to any vac number. I could set it for on at say, 18 inches so it would be off at idle.

One reason I want to do this is that it would make P+G much more do-able the other reason is the hill climbing issue.

Thanks Christ
Vortex generators are old tech. My new and improved vortex alternators are unstoppable.
