Looking for a two way remote start system. i currently have a Viper 160 with pass lock module from directed electronics. I want to upgrade to a two way system so i know if my car actually started. the system works very well now and i spent ALOT of time doing a very neat and reliable installation. So if i upgrade i need to be able to use the wiring harness thats for the 160. I know the 160 is running a 900MHz ant. right now.
