Just run a wire directly from the alarm system to the trunk trigger wire. If it's an add on type then there's no additional relays required but if your tapping into the trunk light then see polarity it is first and you may need to reverse the polarity of the wire so that the alarm recognizes it.

The mercury switch will ground out so you won't need a relay to reverse polarity.

I plan on doing the same thing to my wife's car and just wanted to make sure.
