did a little searching but couldnt find a straight answer. basically my car(91 240SX Fastback MT) is equipped with remote start but it doesnt have neutral safety installed. luckily i dont have a habit of leaving the car in gear, but id like to be able to remote start my car with peace in mind. anyways does my car have a neutral safety switch, if so what color is the wire or do i have to run a wire from transmission?

There is no neutral safety switch like on automatic cars, but there is a neutral position switch, green/orange, found at the ECU. It grounds when in neutral, that should work for you if the unit requires a ground.

i believe my alarm needs a ground signal to disable remote start but i can wire a up relay to make the neutral ground signal work.

when i did my at to mt swap i left the neutral switch unplugged, but im going put the plug back on and splice the wires into the alarm. i havent done it yet, its just hanging but thats what im planning to do.

85 - Neutral Position Wire
86 - ACC(may have to use constant instead)
87 - none
87a - Alarm Hood Pin Wire
30 - Ground
