warranty!

page 2.
NOTE: both Analog and Digital output sound simultaneously, regardless of which type is used.
6.
Use the provided
blue wire

This wire will
output 12v whenever a door is unlocked (via remote) or opened (data-sensing). Make certain this wire
will not short circuit anywhere as it will have power any time the vehicle network is active.
