With you wanting to install poppers, I would guess yoiu are installing electric doors? Might mention something. My Kid had electric doors in a couple of his cars with shaved handles. He used some system with a remote control so that he only had to push a button on the remote to open the doors.

Twice he had to smash out a window to get in, both times at a 7-11 store, because something in their flouresant lights disrupted the signal and made his remote not function. He got very good at taking a piece of spark plug insulator and smashing out a window to get in, to the tune of about a $ 160 each time window replacement cost.

Just thought I would pass that along.
