791xv with 506T+508D Wiring

Hello

I have recently installed a Viper 791XV in my 1992 Olds Cutlass Supreme Coupe.

options:

-530T Window Automation

-529T Sunroof Automation

-103T keypad for ESP system control

-Trunk Popper "Aux"

all working 100% so far

What im looking to do now is add the 506T Audio sensor which i have done already as per the instruction manual for "Adding a 506Tto a DEI system that has a external shock sensorand reports to seperate zones to shock sensor port"

that currently works fine also.....where the shock sensor reports to Zone 2 and the audio sensor reports to zone 4

I would also like to add the 508D doubleguard  field sensor?? how does one add that to the system now that im short on zones?

another thing im having issues with is getting the trunk icon on the remote to activate when i use the trunk popper option?

i get the audio beep but not visual on the remote?

if you have any info that you could pass along regarding this i would be greatful

thanks

Dave
