Viper 791xv, 2003 Mazda 6

This is a dual stage sensor with a wire that can be wired for dual stage or single stage full trigger, but by default is setup/configured for single stage (full alert only) - the green wire (warn away) loops back into to contact the blue full alert wire.

You need to cut the green loop that is located near the sensor end of the connection wire (so that it does NOT loop back into the blue side of the wire harness - just cut the loop is half, near the center) and connect the cut end to the loose green wire. 

The blue wire should be your full trigger alert.  The green wire (that currently connects to the blue wire at the sensor end of the connection wire harness) is triggering full trigger when it senses warn away shock.  By cutting/disconnecting this green wire from the blue wire and hooking it up the the green wire, you should have dual stage functionality.  You will then need to remount your shock sensor to a hard, SOLID surface (using screws is highly recommended) and retest and adjust your sensor's adjustment screw.

Note: I'd recommend cutting the looped green wire in the center so that if you want/need to reconnect it for any reason, you'll have at least a little wire to work with, and can always solder an extention on if need be.

Good luck!

if that green wire is just in with the blue then if it needed to be reconected he could just splice into the blue right? anyways that doesn't matter...

are these common, i have never seen one with the first zone tied into the second like that, that's really strange to me.. but i d k, maybe it's older or something, have you seen these a lot bret?

I have not seen shock sensors that ship with these wires recently.  This type of jumpered wire is "pictured" on several DEI install manuals for audio and tilt sensors where two sensors share a single port plug, but you sacrifice two stage sensor to add the second sensor, then BOTH function as single stage, instant trigger sensors.  See following 506T manual as example:

http://directechs.com/guides/manuals/ig/accessories/N506T.pdf

In other words, you have a two stage shock sensor that plugs directly into your alarm, but you want to add an audio/glass break sensor.  You can toss the dual stage shock sense wire and use the wire that comes with the audio sensor that functions as a Y adapter and plug both the shock sensor AND the audio/glass sensor into the alarm brain in the same port.  At that point, both shock and audio sensors function as single stage/instant trigger sensors.

I don't think this is common and I don't think that this is the default shock sensor for the viper high end alarms.  This is why I was thinking that he got screwed on the sensor and someone slipped an older sensor (and sensor connection cable) into the box with his Viper alarm.  However, I'm not 100% sure on that.

You'll get the most sensitivity from the sensor if you mount it to a solid part of the firewall (with screws as TIGHT as you can get them - without stripping the holes out).

After I do this, I'll turn the sensitivity all the way up and then test and adjust the sensitivity down to reduce falsing.

A solid surface is going to, BY FAR, give you much greater sensitivity throughout the car.

Your sensor, by default, is wired as a single stage ONLY shock sensor.  YOu have to cut the green loop at the sensor end of the harness and wire pin 4 into the loose green wire that comes out of the alarm brain end of the harness to get dual stage functionality.

also, it is much easier if you stick to one post like bobk said.  You have several people trying to help you, but you're getting your notes scattered throughout the forum.  I'd recommend that you post and try to be patient while people check out what you've posted and take time to reply with reliable information that will help you.

I get pretty impatient myself waiting for an answer that I'd love to have RIGHT NOW on this forum, but understand that everyone is not on 24/7. 

Hope all goes well!

Try reading page 33 of the installation manual. It tells you what the green wire is for.

This are pretty common I installed a Hornet alarm/starter combo last weekend and  it came with the same sensor . I didn't use the green wire or cut the loop and both the warning and the trigger work.

 In your case the sensor might be bad, but try mounting it to the steering column and see if that helps. Also make sure the zip ties(this things don't have holes for screws so you have to use ties) are tight
