I'm installaing an Avital Phoenix2 alarm on my 93. Everything works fine from the trunk opening, to silent arming and it seems like the wires are all connected properly. The problem I have is that when I arm it, after about 5 seconds the alarm would go off.

I put it in valet mode and the system works fine. I will recheck the wiring again but has anyone encounter this problem? I think it might have something to do with my stock alarm conflicting.
