installed evo one in my 2015 tundra with OEM alarm. The truck does remote start fine (after the doors unlock and relock) but if it runs for 15 minutes, the alarm goes off. If I remote shutdown right after remote start, it works as it should. If i remote start and wait 5 minutes and remote shut down the alarm goes off. I have hooked up the keysense wire to the black wire as instructed in the diagram. Alarm is triggered when using RF 642 remote or OEM 3x lock. I did use a pre-wired kit that had both plug and play adapters for the Tundra. Updated to 74.49 via flash link but no change.
