The problem with few channels is that when you disarm the alarm, sending the signals to the "poppers" both doors will open. You will have to close both doors before you driver. WIth more channels, you can pop the passenger door seperately.
As for the brake pedal issue, if you connect it properly to the section of the alarm that deal with locking and unlocking your doors, then it will not pop when you hit the brake and lock the doors, cause they will only pop when you UNLOCK the doors. However, when you turn off the car, and it unlocks the locks, both doors will open again.
Going reverse won't do anything cause it doesn't look like anything happens know when you go into reverse.
THis is no simple task. Also, it CAN be done with your alarm, but it will require significant wiring, and perhaps, changing of option on your alarm system with the jumpers or switches, if it has a set. And, you instructions are missing the part abou the locks.
With out all that information, no one can help you.
Again, get a different better alarm, and have someone install the alarm and do the poper connections for you.
