I'm not an expert, but a manual trans doesn't have a true "neutral safety switch" - in my experience, they're only on automatics.
My manual Capri XR2 (with cruise control) had 2 switches on the clutch pedal. When I pressed on the clutch pedal, the switches closed the circuits to
1. Allow the starter to engage when the key is turned to the "Start" position and
2. Disengage the cruise control (obviously, if the cruise control's on).
I don't remember which switch is which but both of them are on / activated by the clutch pedal, under the dash.
Please, Capribrothers, correct me if I'm wrong.
