Not sure if this has been answered elsewhere, but I was wondering how to install a RS unit (specifically which wires to connect to) in such a way that you can use the factory remote and start the truck remotely. I've tried searching and only found the thread on the OS about someone having a RS without realizing it and being able to start it by pressing lock and then unlock three times. I'm fine with that setup (lock and 3x unlock) but I am unsure of how easy it is to do?
