just put one in my wife's 5 speed, it's kind of a PITA cuz you have to take it out of gear, set the parking brake, hit the brake pedal, shut the key off (which the Jeep is still running), open the door, close the door (the Jeep turns off) and it's ready to start via remote. All of which is good cuz it won't 'arm' it's self unless you do this and you can't get out of the Jeep with it in gear cuz it's armed and running when you exit.
I love the remote starts, I have one on my Burb as well, when/if you have one installed make sure they set it to run for the longer time frame, mine is set for 15 minutes and that's not enough time to warm it up.
