Hi I was wondering if the toggle switch mentioned in this thread https://www.thirdgen.org/torqueswitch
would work for locking the torque convertor up for use on the highway?
I have a 305 TBI but I have pulled the motor out and im changing the heads, intake, cam and im switching to Carb.
I will be leaving the Computer in and Im going to tuck all the wires and sensors I wont be using now that im switching to carb, But I need a method so I am able to lock up the torque convertor while im on the highway and this seemed to be an inexspensive answer but also sounds to good to be true.
I know there are kits from B&M but im trying to save my budget as much as possible. So I need to know if this switch is dependant on the computer and sensors i wont be using or if it will actually work?

 

That method does not require the ECM to function.

I wonder if there's ever been a thread on here about using the ECM solely for TCC lockup.
