DEI Alarm Add-Ons

My vehicle is currently equipped with DEI Viper 300ESP (not by personal choice, it came with the vehicle) and I intend to upgrade it with several add-ons. DEI 520T -alarm battery back-up power and DEI 516U - voice warning module. Already a victim of car jacking, and I'm aware that adding these additional components DOES NOT guarantee total security of my vehicle, but I want my alarm unit harder to disable. I intend to conceal my alarm unit and all the additional components from plain site or away from the typical install spot. I need direction on the wiring sequence or possibly a feasible wiring diagram to make all these components work together properly. I appreciate any input, and thanking you in advance for your time.

id have a hidden kill switch installed, alarm options are useless once the alarm is disabled, only good one is the batt backups i thinkThere are 10 types of people in the world, ones that understand binary and ones that dont.

Thanks Infinkc for replying. A kill switch is an option I'm seriously considering later on in time. Love this car, lost so much when it was jacked...even my job. I'm slowly rebuilding her to her former glory but budget is low. I got these extra components for a good price from a friend, actually I don't have to pay him until I get a job. Originally intended for his ride but he sold the car. I forgot to mention the DEI 513T -ear piercing piezo siren, also as added component. I want to install them myself for better concealment and save on installation fee.

I enclosed my own wiring diagram and hoping that anyone can go over the wiring sequence and connections if they're correct or feasible. I'm not an expert by any means (you can tell from the diagram alone), so this is the wiring that I intend to do. I just want to see if I'm doing this in a correct manner, and if I really understand the instruction that came with each component. Pay extra attention to the orange (armed when ground)wire coming from relay to the brain...are the several interruptions (splices) acceptable? Do I need any diodes to any of my connections? Hope you guys can make sense out this. Please, I appreciate any input.
