More info on those WOT (wide open throttle, or full throttle) microswitches here: http://dmctalk.org/showthread.php?13...-s-this-switch
You mentioned having an automatic. You will have two of those WOT microswitches. One is for fuel enrichment and the other is for kicking down the auto trans into passing gear when you hammer the gas. Both of those switches plug into a Tetris puzzle looking connector and both can be plugged into either switch. While the switch itself doesn't matter (flap or no flap, they both activate at the same time), the pair of wires on the car side coming from those connectors does matter. Confirm both pairs are fine and not shorted or mixed up. The wire pairs look very similar, especially 38 years later with a lot of fading and engine filth, but one of them is 'light' green and the other is just green.
