1992 SVX Alarm Issue

[North Ursalia]

I have an interesting issue with my 1992 SVX- the owner's manual and the shop manuals both say the car has an alarm system, as does the little sticker on the side window. There is an alarm brain in the vehicle, and on perhaps 2 or 3 occasions, it has actually gone off with the horn honking and lights flashing and whatnot. It did not come with a remote keyfob when I bought it.

What is odd is there is no security switch in the car- there's the cruise and fog switch, but where the security switch should be, there is none. There was a metal toggle switch on the driver side kickpanel by the diag connectors, but it was not hooked up to anything, nor is there a harness there for it to plug into. It looks aftermarket regardless.

Question is, how is the system activated/deactivated without the security switch, and more importantly, how can I program the fob I purchased without it? EVERYTHING I find says it should have the security system and the switch. I am on the threshold of just buying that bank of switches from a wrecking yard and give it a go, but is there something I'm missing?

Thanks!
