2005 altima not starting

I am trying to install a remote start  on a 2005 nissan altima 4 cyl u\when I hit door unlonk the brain clicks when I try to remote start it I hear no click

I have not installed the control safety switch not sure where that wire is from the ecm do i need that to start the car and if so is there any way to bypass that switch or hot wire or somethin I can not find they wire from the ecm plus not 100% sure how to install that switch everthing else is hooked up though.

The neutral safety wire needs to be at ground.....what kind of r/s are you installing?  You have to remember that you have 1 ignition wire, 1 accessory wire and 2 starter wires on a Nissan vehicule.

Also, depending on the brand of your r/s....if don't have virtual tach....you need tach and you need to program it...
