does anyone know what color and where the neutral safety wire is on a 2007 nissan 350z with a manual transmission? thanks in advance.

Pin 109 at the ECU - brown in color.

The service manual shows that it reads 12vdc when the tranny is in neutral and 0vdc when in any gear so you may need to reverse the logic of the signal (with a transistor, preferably).

I know the older ones did, I've never done an '07. It's always possible the FSM is wrong - I've found quite a few errors in Nissan manuals.

Did you find your wire...? and did you get done with what you were trying to do? (what were you attempting?)

no i havent found the wire. its a friend of mine's car. he bought it with an alarm and remote start but since its a stick whoever installed it didnt hook up the neutral safety wire from the remote start so it will start in any gear. and he doesnt like that so im going to hook it up for him. i was pretty sure theres a wire that rest at ground when the car is in neutral that i can use but if not and its only the brown wire i was told about then i can just use a relay i suppose to switch that wire to negative for the alarm.

How about using the positive brake shutdown wire instead of the negative hood shutdown. Just make sure you Diode isolate the Neutral Saftey wire from the Brake Wire, this way when you put your car in neutral the brake lights won't come on. Hooking it up this way will require no relay draining on your battery, just 2 diodes.

If it does show 12vdc in N then the + brake shut down won't work.

If you need to change the polarity and want to use a relay, at least use a reed relay - you don't want the relay to click every time the car is shifted in to N (which is why I recomended using a transistor).

Your right, I was thinking of a suburu I had done like that. Different application. It wil not work on this car, I should have read KPierson's description of the Neutral Saftey wire better. Use a relay or as he recommended a transistor.
