clifford rs3 installed in 02 denali

Can anyone help with my clifford rs3 installed in 02 denali? I purchased the truck with it already installed.

I originally thought there was a rsx 3.5 installed when I bought the truck. After pulling everything apart it seems I have an rs3 brain with rsx 3.5 remotes and after that there are a multitude of problems I've found:

1. instead of using dome light monitor, he installed a proximity sensor by disconnecting shock sensor and used only prox. sensor

2. factory alarm keeps going off when truck is left unarmed for a period and the door is opened. The only way to shut off is to put key in ignition.

3. I searched this thread for rs3 wiring diag to no avail lotsa rsx3.5 but that one is just different enough to make me post this thread.

4. radio stays on after remote start

I don't have a receipt but i've installed a fair amount of alarms so i'm not new to this, but clifford makes it exceedingly difficult for consumers to work on their alarms (as we all know). I am hoping someone here can help with diagram, I read enough in here to know I might need 456g module for factory alarm, and I need to send neg pulse to door circuit for radio but I have no idea how to go about this without diag..

Thanx
