Greetings-
Long time lurker, first time poster. We've had a rash of vandalism and theft in my area. Recently I had a Pioneer AVH-P3300BT stolen from my car. So, time to install an alarm on the truck since I just installed one on my bike. Back history: Electronics technician and sophmore EE with 10 years of component electronics repair/maintenance and I've done a butt load of car stereo installations but this is my first alarm on a car. I have read through the manuals and various Trailblazer forum posts trying to get a grasp.
Vehicle:
2002 Chevy Trailblazer LT (w/o Bose /w OnStar /w factory keyless entry
Viper Responder 350 two-way (not using remote start option) #3305V
Xpresskit Nexgen DBALL interface (have to program for the truck yet)
DEI 508D Dual Zone Motion Sensor
DEI 506T Audio Sensor

Issues:
I have been putting off this install for a few weeks now while trying to research the install. From what I have read the Responder 350 lacks a Data-2-Data port, so I cannot use D2D and will have to use W2W which isn't an issue for me. Is this correct?
According to Viper, this unit has two aux inputs; hence why I bought both the 508D and 506T. Yet, I only see one aux input on the unit. From the research I've done, I am able to splice one of these in to other wiring. I also read in the manual I am not to plug any high current draw device into the Aux port so this would eliminate the motion sensor from being plugged into the unit. So the glass break sensor would be plugged into the auxillary port while the motion sensor would have to be spliced... correct?
Regarding placement of the motion sensor... The center console in my vehicle is mostly covered by my seats. There is a small space under neath my front cup holders and shifter I could place this. The center console ends where the front seats end so I can't place it in the center of the vehicle on the floor. Although, I could lengthen wires easily, and put it inside the headliner. Thoughts? What are the limitations on this unit? How much plastic, leather, etc will this go through yet still be effective?
Regarding the placement of the brain... I have heard some say go ahead and mount it to metal yet I have read in the manual (and online) to mount it to carpet. Opinions? The more sensitive... the better.
Finally regarding wiring of the DBALL and 3305V... What is the unit that interfaces with the vehicle for the most part? To me it seems like the DBALL. So how I have it in my mind... is I wire something like this:
|Truck Wiring|<-->DBALL<-->3305V<--506T and 508D and any wiring not used by the DBALL
Am I correct with this assumption? So most wiring to/from the vehicle harness would be handled by the DBALL. Any that isn't, will be wired up to the alarm brain. The glass break sensor will connect to the 3305 brain via the auxillary port while the glass break sensor will have to be spliced into other wiring coming to/from the 3305V.
Does anyone think I will have to purchase any additional relays? How does my setup look; do I have everything I need or was there something I overlooked? I have plenty of wiring, taps, solder, heat shrink, etc, etc.
Also, any other suggestions anyone has would be greatly appreciated. I plan on taking my time with this and go step, by step, by step just like anything else I do the first time and double and triple check my work.
Sorry for the long post, but I have done at least two weekends worth of research and have found a lot of info, but none of it comes together (different car/wiring/setup but same alarm, different DEI accessories, different alarm/remote start but the same car). Again, thank you in advance!
