Hello everyone, I did wire back up alarm on 2008 sierra , hook up from tail lights. Then when you unlock/ lock the door tail lights on , alarm start beeping. Wondering if any other ways wiring the alarm. Thank you.

hook them to your reverse lights

There should be a box towards the back of the frame. It has all the taillight connectors going into and then out of it. There's usually a reverse alarm wire to tap in to for when they're cab&chassis trucks
