99 mustang gt trunk alarm

My alarm on my mustang keeps triggering due to the trunk. I know it needs to diode isolated, but I can't find the diagram showing where to put the diode and which direction. It needs to be at the GEM, but that's all I got. Any help?

Do you have more than one sensor wired into the same wire for the alarm? (Example: Door triggers, and trunk trigger wired into the same wire for the alarm?) If so, how do you know that its the trunk that is triggering the alarm if its not diode isolated? ------- I just checked the vehicle wiring for your car listed on this website, and it has the trunk trigger wire listed as a (-) and the door triggers listed as (+), so I would hope that you did not wire these into the same wire from the alarm. What alarm are you using? If you do not have anything else wired in parallel with the trunk trigger wire into the alarm there is no need for a diode because you would have nothing else to isolate the wire from.

I'm using my Viper 791XV which shows me the trunk when it goes off. The GEM false triggers it about two times after I arm it everytime. According to DEI, I need DirectFax document 1076, but I don't have a fax machine. I worked for a Professional autosound place here in New Orleans before Hurricane Katrina, but when I got back from Iraq, the place was totally underwater, so I'm kinda rusty. Anyway, I'll pass by one of their other locations when I get off duty and post the results here to help anyone else.

Fax machine? Just log into directechs.com and click on resources....then Security. All the popular directfax documents are there. The password from when you worked at a shop probably hasn't changed.
