Installing Remote Start In ’96 Intrepid

OK i have never installed a alarm before but i did quite a fiew stereos so i have some basic knowlege.

I have a Crime Stopper CS-2011RS remote start/alarm which i will be puting into a 1996 Dodge Intrepid and i have a few questions.

1) I have some sort of feature that locks the doors automaticaly after i hit 15mph. Will it affect the install in any way?

2) Were is the Dome Light activation wire? or should i just tap into the door triger switch?

3)Were can i tap into the TACH? It says Coil Pack But i dont know were that is.

4)Were Should I mount the Shock Sensor?

5)I have 2 Ignitions why is that? what is the diference between the two? should i connect both of them?

6)were is the best place for the brain in this install.

7)There is a need to connect 2 positive + wires directly to the battery how should i do that? should i just take 2 wires and Put them around the + battery terminal or is there a distribution place there.

Thanx for looking at my post if you have any additional comments/tips let me know if you feel like answering only 1 question please do so any help would be nice

my alarm has a wire labeled (-) 500mA Dome Light Illumination Output

i dont know exactly when it illuminates the dome light. is it when you pull the key out of the ignition? anyways i want to hook it up to the DOOR TRIGGER(-) wire but i think it might give problems. for instantance when i open the door how will the alarm know i opened the door scince this wire is showing ground and how will it know when i closed the door scince the  Dome Light Illumination Output will keep the door trigger negative. im guessing the alarm will arm(lock) when all the doors are closed but this Dome Light Illumination Output will create the illusuion that the door is open.  

OK more pre installation questions. i have a whole bunch of rellay that i will be installing to aid the alarm including:

dome illumination

Trunk Pop

and these relays require 12v constant and ground. should i just run a additional fused 12v and a ground wire and connect all the relays to it. if so what fuse should i use. i am also very interested in installing the passanger door unlock feature which makes it so that first press opens driver door and second press opens the rest of the doors. now i have a crimesopper cs-2011rs III alarm and a dodge intepid 96 which has positive door locks is it possible to install this feature. i also heard that this dodge has a posibility of burning out the door acutators has anyone else herd this or knows how to prevent it.

OK i have another question how come you have to connect  the Airbag light(third ignition) through a relay, why cant i just connect it to the second ignition wire on my alarm.

another question i was using a multimeter to test wires and i came across somthing weird. the wire to which 12v is aplied to open the trunk showed continuity with ground meaning it is ground. if that is so shouldnt the aplication of 12v to that wire cause a short.
