excalibur al 1810 ground while starting

Could someone please help. I have a Excalibur al-1810-edp could someone please tell me which wire is Ground while remote starting on this unit. Also do I need the neutral safety wire since the newer cars wont let you take the key out unless it is in park. Also I noticed that you have to hold down both the lock and unlock button at the same time for remote start, as there a way for me to change this. Any info would be appreciated.

If memory serves me right, you can use the orange wire in the small harness, or the blue wire in the 3 wire harness.  Both will act as a ground while running wire.  You need to ground the neutral safety wire for the unit to work.  You can use it as a neutral safety, a turbo timer, or what I do is just ground it, which is also mentioned in the instructions.  There's no other way to remote start it other than pressing those two buttons at the same time that I know of.

Thanks I played around with it and got it to work. Only down fall is that I use Idatalink bypass and the d2d is not a direct fit had to hard wire. Thanks Travis
