Your local toyota dealer should have the wiring diagrams for the TVSS IIIB alarm with the installation instructions

(i believe the alarms were fitted at what they call

'point of entry' ie when imported into this country) which was fitted from july

'95 onwards on the mr2 i think.

If they are a friendly dealer they should let you have a look

- mine let me borrow theirs for my old carina this weekend but obviously due to security they might be reluctant

!
