Rooz,
Per your last question, I did not get a chance to install the 530t yet (Installing 2, one for front windows other for rears). I was missing two wiring harnesses which I need because its for the 4,5,6 channel for the alarm. I have to go back to the shop and get the the seller to give me those wires. Lesson learned: always double check your box for contents when box is marked display.
As for installing the 530t's, its quite simple. The trouble is running the wires to the doors. I am going to double check on this because I might not need to run them to the doors. This project is going to be a longone because I work full time and go to school, so please bare with me.
I will post the pics of the "alarm and components" up tomorrow.
