Audio Systems: Adding security mods to my viper system?, viper 791xv remote start, sorry chap

Question
Hi, I have a 99 chevrolet TAHOE, and I have the Viper 791XV remote start system and I just ordered the Directed 516U Universal Voice Module, ScyTek WR84 ( SMART4 )4 Windows Roll-Up Module, Directed 620V - Viper Electro-Luminescent Logo Badge, and the Directed 508D Invisibeam Field Disturbance Sensor.  The guy who installed the system originally has moved and I have no idea how to hook this stuff up. Could you give me some help on the wiring I should look for and hook up? Thanks!

Answer
Sorry chap, all double Dutch to me, none of this stuff, including the vehicle, is used over here. Please try a USA based expert. But having worked on Clifford and Cobra systems with similar features I would recommend taking it into a shop as it is very complicated and you could do a LOT of damage very quickly, even to the ECU and that you do NOT want to do $$$.
