its on the steering column just above the firewall
I am having the same problem I was thinking more ignition switch, but like your idea more
No.
Remove the retaining ring at the top of your 1985 Chevy ignition switch. Slide the ignition switch out and remove the wiring harness. Reverse the process to install the new ignition switch.
YES.
It does not have a sensor, It has a switch and it is mounted just above the brake pedal.
No, completely different body style.
Yes it should bolt right in
You have wires going to the carb on a 72 Chevy c10?
A c10 is 2 wheel drive and the k10s are 4 wheel drive.
yes it is
The last year for the 327 in a C10 was 1968.
I don't have a diagram, but there would be one steel wire from the switch to the hot side of the coil.
