Hello Chris
You are welcome to the forum.
[congrats Phil, you were up earlier than me again!]
There is an aftermarket alarm on my car, and I have no idea how it is wired.
You could look into the How-to section, I found this there:

One word of advice for you; the workshop manuals most of us have are American, and the wiring is different in some ways to the Euro version. In relation to your particular problem, the US cars come as standard with an alarm [security] system. European ones don't.
So the wiring may be a different colour.
Another factor with the wiring, early 92-95 cars are OBD 1 compliant. The later cars after '95, are OBD 11, so their wiring will not be the same.
[Speaking in general, the OBD 11 cars are the ones that do not have the black roof] If your car is any other colour than black, and has one colour all over, it is OBD 11 wired, and may be different from the wiring you have been sent for an SVX 92 model year.
Keep us posted how you get on with it.
Joe
