Foxguard alarm

I don't suppose anyone knows what security system would be fitted to a 93 Disco.

I have a black and grey single button fob with a 5mm plug in jack plug for an immobiliser.
The system appears to be Foxguard.

My insurance company won't insure me against theft until i tell them what it is.

Foxguard finished about 10 years ago, they were bought out by Toad then binned!! The Immobiliser plug sounds like the old JR50 system, the alarm could be any of the old models but if your insurance want a Thatcham System i think you will be buggered as they won`t recognise anything 5 years after it`s been discontinued.
