pl green to to key sense wire that goes to ground when doors is closed
pl blue wire goes to yellow wire
pl violet wire goes to starter wire
pl pink wire goes to ignition wire
pl black wire goes to black
pl red wire goes to 12v constant
pl brown wire goes to remote start

I been to the library the internet and to the dealer they are not showing a key sense wire
They may not be a key sense wire.
