I finished all the wiring and checked it million times. When I press programming button and plug the 6 pin connector, let go on blue, connect 20 pin, antenna, valet, and can bus, put the key turn to on position LEDs go out.<br /> <br /> I tried turning on option 20.2 but when I plug the 6 pin connector all lights flash then they go out and nothing. I&#039;m I missing something?<br /> <br /> &nbsp;<br /> <br /> EDIT: Turned out my antenna was faulty, everything works great now.
