Factory Alarm Hood trigger-1996 Ford E350-wiring ends location needed

[jimtmcdaniels]

Hi, my 1996 Ford E350 van didn't come with a factory alarm but I found in the salvage yard, an alarm trigger for the hood and installed the trigger.
It fit perfectly in the factory mount position and the plug end connected to a plug lead factory harness that was already in my van.

I'd like to connect this hood open alarm trigger to an aftermarket alarm system but I don't know where the wiring in the harness comes out at....

Anyone know?

I've attached a pic of what I'm talking about.

Thanks
