Follow up - I'm about half-way through the door popper install, but not quite done. I forgot how much I love running wires in cars (not).

Anyway, a couple of questions for anyone that might know...

1) what kind of wire should I use to extend the length of the antenna wire? Copper is probably not going to work, but I don't know what would.

2) has anyone ever checked if there was an output from the alarm system activated by the "option" button? If so, I'd wire it to a relay that would pop the read-door solenoid circuit, so I could open the back without the key.
