The linkage from the trans to the bellcrank on the subframe and from there up to the lever at the bottom of the steering column is connected to a tube inside the column which moves the "collar" just forward of the steering wheel; it's there to only allow the ignition to be turned into the "Lock" position (so you can remove the key) when the transmission is in "Park" - it's explained in your Owner's Manual. Most headers interfere with the linkage, which must be removed, so guys with headers and a floor-shift automatic usually wire the lever at the bottom of the steering column in the full "up" position to the brake booster bracket, or manually turn the "collar" fully counter-clockwise in order to be able to turn the ignition to "Lock" and get the key out. With a 4-speed, the tube inside the column also operates the backup light switch, but the backup light switch on an automatic is on the floor shifter.
