The 1966 Chevy Impala ignition switch can be removed by loosening the retaining ring at the top of the ignition switch. Remove the wiring harness. Reverse the process to install the new ignition switch.

A 66 Mustang regardless of engine doesn't have an ignition module from the factory. It uses breaker points inside of the distributor housing to directly control the ignition coil.
Undo the chrome ring at the front of the ignition, the ignition switch assembly can then be removed from the back of the dash. Unplug the lead in the back remove the ignition switch & throw it in the bin. You could try drilling the barrel out, it would probably be best to buy a complete new assembly, you wont get the old barrel out without a key. You will also need new door locks.
at least 3
2 screws on the bottom part of the arm rest is the best way.
Could be a bad ignition switch....
To replace the headlight switch in a 66 mustang, you first have to remove the instrument cluster housing. After you have that out of the way, you will see a small button on the housing of the switch mechanism itself. Pull the switch knob all the way out, as if turning on the headlights, then push that little button and the switch stalk will pull all the way out of the switch housing. Then unscrew the switch bezel, pull the switch housing back, so that it clears the dash, unplug that big wire connector from the side of the switch, and remove the switch entirely. To install the new switch, you just do what you just did, except do it backwards.
Unscrew bezel and switch should slide out through the rear (under dash)
Just remove one screw inside car, under the dashboard near the ignifion switch area.
Bad ground or bad switch
