requesting real life experience with 904 lock-up with manual switch

I like the switch idea, might way to tie it to the brake pedal so if you hit the brake the converter disengages.

maybe even make a relay to controle it so touching the brake disengages it till you turn it on again, not a super complex cir.

Dana - an electrical engineer I'm not, but I am good at following directions! What is an N.O. relay, an N.C. relay and an N.O momentary? Where might I acquire these items???
