*1 Use relays - requires high current ground to operate

Is up to the installer to test all wires with a DMM whenever possible.

Luis, your last reply didnt come through. Please post.
Also, I went back through 12volt and found this:

This one says unlock is reverse polarity. How is that wired into an alarm?

go to the door lock section and see how to wire relays to give you a negative trigger Every where I look I see car as having negative locks that require a strong ground
