HI, I just recently swapped a whole drivetrain from a 1970 Formula 400, into my 1970 Esprit.
The esprit came with a Turbo 350 auto trans, and had an electrical connection on the passenger side of the trans. Can anyone tell me what this wiring plug is for?
Also, I did swap out the stock Turbo 400 wiring for the kickdown on the gas pedal side. But how do you wire up the kickdown switch to the turbo 400 trans?
Any help much appreciated.

It would be better to use the original harness if you have it. The switch on the pedal has two prongs. One connects to the fuse box and the other connects to the switch on the left side, drivers side, on the transmission.

As far as I know the 350 has no electrical connections on it and a cable controlled kickdown.   a picture of the wires in question on the 350  may be helpful.

It may be a 350 lockup. It would have a plug for the converter solenoid

Whatever a 350 has in it, it's not an electric kickdown.  There are lockup 350's, and there are some 350's that know what gear they're in (for computers to know).  There might also be some switch pitch 350's, although nobody ever told me that.  I'm just speculating.

Whatever it is, you won't need it on a 70 Formula transmission.  What you need there is 12 volts, through the switch, to the transmission.
