I installed the evo all on my 2015 ram tip start using chrt6 harness. I made it sucessfully through the programming procedure, then decrypted the key fob data and reinstalled. The truck will start and run for about 3 seconds and then turn off and the dash briefly displays wrong key fob. Then the process repeats itself. Notes on installation... to make as few splices in my new wires as possible i bought an OBD2 connector and soldered the can high and low to the correct pins on the connector and plugged it in. I have also not hooked up the RAP wire due to not seeing the same connector in the correct spot in all the data sheets. Is this RAP wire just to verify the doors are closed? I saw a video on you tube and the installer said it was an optional connection and not necessary for the remote start to function. Is there a possibility that my key fob code isnt being correctly decrypted? Any help or suggestions are appreciated.
