I've got the pictures.......but this site is disfunctional today. I tried four times to send the jpg and the site falls on its face. The clutch switch is the first one up from the pedal, then there is a second one at the top. That one is the interlock switch. It just controls whether the starter works or not. The lower is the one that sends the ECU a signal that your clutch is in or out.
The neutral switch is on the right side of the transmission and the over the top(fifth) switch is on the left side of the transimssion.
Maybe late tonite I'll jpg the pictures. They are in the Fuel and the starter section of the manual at http://www.iluvmyrx7.com
When in neutral, the neutral switch sends nothing to the ECU. When its pushed in, it sends a ground signal to the ECU.
When the clutch switch is pushed in, it sends a 12v signal to the ECU. When its released, it sends squat to the ECU.
The clutch switch also acts in relation to the cruise control. thru the same switch. But that 12v goes to the cruise control box .
On my n/a I have the interlock sw jumpered so I can start the car without depressing the clutch, and I have the clutch sw thrown as far as I could throw it into the street when it broke apart on me four or five years ago. Left the connector dangling there. I turn my cruise control off by stepping on the brake pedal and have no clutch input to my ECU.
