If you can get to the terminal on the starter motor, yes. Or the alternator (a bit more difficult). Has the car been fitted with an Anderson connector to connect jump leads?
Yes, no probs, I have a Accumate mounted in the Griff's boot. I always back her into the garage and leave the boot slightly ajar so I can plug it in. Doesn't seem to affect the alarm at all - I don't believe a boot pin switch is fitted.
