Alarm system interim solution

[GSpreeman]

I am in the process of selling my house, buying a new one, and last week just got my first 911. I know I need a good alarm (maybe a lojak) but in the interim, due to lack of excess cash, what fuse can I pull so that they can't start it? I have no idea which fuse is which (it's a 1987 911) so if you could be explicit with which one to pull it would be greatly appreciated.

Thanks,

Greg
1987, 911
