05 grand prix, remote start

Double pulse won't work on this wire(no matter how many times the key is turned to unlock in the driver's door cylinder it will only unlock the driver's door). If the remote start had a second door unlock you could send this to the unlock wire but the 501 doesn't have this. You will have to send your unlock wire (Blue)to the ORANGE / black in the car. Then use the factory alarm disarm wire to the purple wire in the car. The other issue this will cause is the door will unlock before start so the pulse after start will have to be wired to the RED / black lock wire in the car. Hope this helps.
