Has anyone fitted a battery isolator to their t350

[MOM]

Hi.
Hoping to pick up car next week - YIPPEE

And now just trying to think ahead. I am assuming that the alarm immobiliser will drain the battery within 3 days if not used just like my Elise. On that i fitted a battey isolator (cut off switch). cheap to buy & relatively easy on the elise bar the backache.
Understand that the t350 battey is also hidden in the bowels of the car & wonderred how othes may have done this.
Oh yes & just to stop wasted posts yes i know it will turn off alarm etc but the car could still not be started so i am happy with this solution. eg after 4 months my elise still started.

Anyone please?

Regards
Mark
