Don't have a picture, but on my truck it runs along the intake manifold and then to the transmission. I don't recall seeing it go inside the truck.

Thanks but the kickdown switch on mine is mounted to the gas pedal bracket and activated with a switch
wiring if from switch and fuse box through firewall to the tranny

Mine's a '70, so they moved it inside some time after that. That's a better place for it, really.

My 72 kickdown wire goes through the firewall with the oil line grommet. 2 holes in grommet. One for kickdown wire and one for oil line.
