I'm planning on adding an aftermarket alarm to a 2008 G35, but dont want remote start,window roll down etc..

I want the following :
pager alarm
typical door ,trunk,hood triggers.
radar sensor & shock sensor.

which alarm will work for this application ?
clifford, viper ?

I want the radar option, because THIS is what makes the car beep, EVEN without touching it, its radar detected, and my previous car it worked great. i had a clifford intelliguard 800IQ with radar.

I only want the alarm for night parked protection basically, dont even need it to open teh doors etc.. just monitor / and alarm basically.

I need the wiring schematic for an 08 G35, i think it will be the same as the 07's ?
got 2 questions .

#1 is 07 wiring and 08 the same ?

#2, where can i find the wiring schematics for the electrical ? (im going to install aftermarket alarm) . I've done it before, but need the cars schematics to see where im tapping into.
thanks alot if you can help guys,
