first off, and this is just my opinion, I wouldn't buy a kmart brand, spend a few bucks more and get a good name brand one like astro start or something like that. who knows, maybe you sped 6 hours installing it and it dosen't work cause it's kmart crap. Second, does the car your installing it into have an alarm? if it does, the alarm has to be disabled, unless it's an aftermarket alarm that will work with a remote starter. for the remote starter to work the alarm must be disconnected because of the starter lockout on most alarms. also, your going to need all sorts of crimping connections (if you want to do a good job) a wire stripper and crimper. a wiring diagram would help a lot if you can find one, otherwise your going to need the manual to the car, and a wire tester (to find all of the different wires to crimp into) and I don't know if you've looked at the box that you have to hook up, but there are like 30 wires comming out of it. it's definatly not the easiest job in the world to do. I tried installing mine in a 96 explorer last fall and about 7 hours later it finally worked, and a few phone calls to a local car store where i bought it. If I were to do it again though, I would've definatly paid the extra 100 bucks and had it installed. my .02 tho.
