Hey Guys, For those who didn't know, you can hook up a beeper or siren etc so you get sound (two beeps) when you lock the door with the factory remote without using a relay. I happened to find and old alarm horn in my garage and thought I'd give it a try. Followed this guideline:

VQPOWER

I hooked my ground to the orange wire and my power lead to the green with orange stripe wire, there are three but I used the one closest to the solid orange BCM lead (ground), I just pushed my two wires into the plug and mounted my siren under the rear bumper. Works great! FREE!
