Could have been one of those quick fixes on a trip that never got properly fixed.

thats far too sensible an idea... I presume the classics have always had these actually connected? Never actually been dumb enough to try starting in gear...

Try a multimeter on the plug to the pedal. Maybe the switch failed and someone just bypassed it to save $

Googling may indicate its just a bypass to prevent needing to press the clutch to start the car? Confirm/deny anyone?

Heres a weird one (maybe), was doing some work under the dash looming some new cables and spotted this interesting item:     Anyone know why these matching plugs might not be joined for the clutch pedal, or why its just been jumpered? Car is MY00 GF8 STI...
