2005 Sequoia everything works fine, but the factory alarm goes off during autostart 80% of the time and it shuts off using the 160XV remote...

Anything I might be missing??? o I hook up the yellow/ green to what on the Remote Start or the 556U.. I hooked to blue (ground out when runnning, that is also being used for the 556U)When I remote Start it just cranks and does not Start.

If you are using a ground while running on a bypass, as well as the keysence... you will need to isolate with diodes.

And yes you need both, the keysence and the bypass.

use the blue status to turn on the 556U and use the blue/white second status to trigger keysense....

you do not need to hook up the keysense wire of the 556U on a Toyota....
