'95 Suburban anti-theft system question

I just bought a '95 'burb that has a gm delco antitheft system that looks like its a dealer install. The module has been disconnected, and there's no paperwork pertaining to the alarm. 3 questions:


The harness uses 2 fuses, a 20A which is installed, and another one which isn't. What current fuse do I use?

How do I operate this system? The burb has keyless entry - ˆ assume that matters

Theres a momentary pushbutton under the dash. I assume thats a valet switch. How do I use that.

Thanks in advance
