vt_mav, I know Raque Thomas did a write up on how to get the rear door popper hooked into the stock key fob. I started to do the mod, but got my wiring a little crossed so I put it back to stock and haven't been back in to fix it yet.

Here's the thread: http://www.vehicross.info/forums/showthread.php?t=2069 Looks like the links to the diagrams are broken. I have them printed out at home and I could draw them up and post them up here if you're interested.
