sure thing (note it is a safety concern. if you have an alarm, you can tie it in with the starter kill - use blocking diodes - so if the alarm is on, the popper is dead).
But you just use a constant power source for the popper instead of key-on. the popper has one wire which is hot any time the key is on - that is the source. that wire is removed.
or if you install an alarm, the popper can be left original and the alarm fob can pop the trunk any time (how I did it).
good luck.
