According to Rave, MGR discontinued fitting interlocks except for a few overseas markets. In these cases, a solenoid is fitted at the bottom of the gear lever which prevents the lever being moved from Park unless the ignition switch is in position 2
and the foot brake is applied. My car does have an interlock but it's not connected to the brake. I don't know what it actually brings to the party though. A header has definitely not been removed - the wiring loom is virginal. It's just not there because it was only used for cars with cruise, parking sensors and the brake application of the shift interlock fitted.
Incidentally, the mated headers in the engine bay resembling towing electrics plugs, are still only headers albeit different shapes to the normal oblong ones. The only connection of interest to the project has been the digital signal from the ECM to the cruise interface saying "ok, I'm configured for you" which was only partially fitted in the factory. I had to extend it from where it had been capped off to the cruise interface.

According to the diagrams, it is connected (somewhere) to the auto transmission (C0932-43). The cruise interface also connects to that pin, but both are inputs to the EAT.

The signal from the engine ECM is a digital variable square-wave voltage between 0-12v. It's not a standard +12v supply. That signal is getting through (it's specified in post #79 above).
