Id just like to say that XOC is freakin' frackin' awsome
saw this a while back and decided to do it to my X with my driveway gate remote. I took apart the blank and drilled a huge hole to put the push botton there. I then solder the button to the remote and velcro'd that under the dash for easy battery replacement in the future.
integrated remote thread as i was doing this i was taking out one of the blanks near the 4X4 knob and disconnected my passenger airbag connections and started the X. this thread helped me reset them back. and yes the 2nd method does work for the passenger airbag as well.
