I think you've got all the facts there. The manual switch to interrupt the OD solenoid like you've hooked up is my Plan B at the moment but it would still require you to "switch-lift-mash" in order to drop out of OD and accelerate. Doing all that by just mashing the go pedal is the slick setup I'd like to replicate while using HEI.

When ya let off the throttle the solinod gets power back and ya go into O/d again. So, anyway you probably know all this and I might not be totally correct, anyway. The only thing the system does is complete the ground circuit to the neg. side of the coil. . The gov. is already grounded at hway speed so a switch that interuped that circuit would bring ya out of over drive but you would still have to let up on the throttle to release the sol. pawl. That's why I don't use the kickdown interrupt. I have a switch in the wire goin to the sol. to kick it in and out. The ground controled relay to bring ya out of O/D at 25 mph is a good idea, but the kickdown is a whole nother pain,
