Ok, as per my previous thread about the best way to lock-up the converter I'm taking the advice there and using a TH400 1Pin connector & the N/O 4th gear pressure switch.
I'm also going to wire through the brake pedal switch to unlock when I apply the brakes.
In researching the brake pedal switch thing, I found most people just add a N/C relay to the switch... since the brake switch is N/O. Then when you step on the brakes the circuit relay contacts open and unlocks the converter.
Another option I found was to use a brake switch off a 1980's GM car (like the Buicks here :biggrin: ) that has cruise control. Evidently, that switch has 2 sets of contacts... one set N/O for the brake lights on the bottom and the other N/C on the side for the cruise control.
That may be perfect for my application which is a 1966 chevelle.... but I'm not sure if the diameter of the switch threads are the same. I circled what I mean in the picture below.
Anybody know the thread diameter circled for the Buick... of course my local autoparts stores don't have any in stock so I can see them and I'd hate to order one just to find out it doesn't fit.
