I have a 68 Cutlass S that had a 350 and two speed jetway. I've changed it over to a 455 with OG 400 transmission. I need to know what wire I need to go from the transmission to the switch on my pedal. I also have changed over the pedal with a kickdown switch on it. I need help to figure out how to wire it up properly. I know one wire goes from the transmission into the switch on the gas pedal, and one wire I think goes back to the fuse box, but I am not sure. Any help would be appreciated.

Thanks, Bob.

The Jetaway used the same switch and wiring as a TH400. Everything you need should have already been in the car.

There are no wires that is why I need info

The car left the factory with the wires. They are built into every 68 harness, no matter what trans you have. Has someone cut them? How did the Jetaway kickdown work? Is there no switch on the accelerator pedal? In any case, The switch has two terminals. One gets switched 12V power and the other runs to the trans. That's all there is to it.

As Joe said the wiring should already exist as they were used for the old 2 speed trans you removed.
