Is this acurate knowledge?

I also have a few questions:
Do i need to connect the 2nd ignition output?
Where should i connect the Ignition input?
Will i use the ground when running wire?
Do i need the positive door input wire?

Are there any factory alarms systems i have to worry about?
Should i connect the armed output, factory disarm, and factory rearm wires?
