Need Help with alarm wiring

[Cameo]

I recently purchased a Steelmate 986 series alarm system for my 2006.
The problem is the instructions are not that clear.
My questions are:
is this an Ac ignition or a DC ignition?
Where does the orange wire originally come from?
is the contact on the relay the orange wires, that would mean that the grey wire would be a negative signal from the controller?
Where does the blue wire go to?
There are 3 wires going to the ignition switch and they are only showing two%
can anyone help?

Thanks

Can anyone at least tell me if its an AC ignition coil or a DC ignition coil, would be much appreciated, I asked the dealer and he hesitated and had to look for a while and still wasn't sure when he said "it must be DC".

Thank you
