Possible to start engine without depressing on clutch??

In the transmission section of the manual it mentions a park/neutral switch connector for the 6MT for vehicles with and without S-mode so that might be something you can tap into. See page TM-44 for the exploded view (item 6).

In the BCM section of the manual it is referred to as the "SFT PN/N SW". It appears to connect to pin 140 and is at 12V (battery voltage) when in neutral and 0V when in gear. See BCS-68.

Thats great. Just might work but i gotta check my car first and see if its actually there. Unfortunately my car does not have S-mode. The service manual says the switch is there s-mode or not, but the BCM section says pin 140 is only used if you have an A/T or an M/T with S-mode and nothing on M/T non S-mode. Even if its not, its the same transmission case nearest i can tell and the neutral switch and plunger only come out to $20. Not sure how i missed this but thanks for pointing me in that direction! I naturally assumed there would be no neutral switch.

The transmission manual indicates the neutral switch is there for both with and without S-mode but the BCM manual indicates it is only present if you have S-mode. Either one of these 2 manuals is wrong or there is a wire going nowhere. Hope you can figure out a solution.

So i put the car up on the lift last night. The switch is there. Anytime the ignition is on, 12v is sent to one side of the switch, in any position of the neutral gate the switch is closed and it does in fact send 12v to pin 140 of the BCM but also branches off and sends 12v to pin 109 of the ECM. Ovolts are seen in any gear. Should be easy to tap into.

Very nice. Those doing remote starters on the 6MT will find this very useful. +Rep.
