viper 5901 onboard shock sens not enough

I have the DEI Viper 5901 in a 08 Toyota Tundra and the onboard shock sensor is not sensitive enough. I also added a 506T Glass Sensor which works damn good. I want to add another double guard shock sensor and don't know where to add it on the alarm. IT has 4 wires Red,Yellow,Blue and Green.   My GLass sensor plugs into the DEI on a 4 pin port but the wires are only Red, BLue , and BLack.   Is the best way to add the shock sensor on this same 4 port or add it to an aux channel? Thanks In Advance

You have to adjust the onboard shock sensor with a bitwriter (not that that answers your question).Big Al

I did that and own a bitwritter. IT is at 15 which is max. I would like to add another and need to know where to tap into to do this.

bump for an answer.  I have my truck taken apart to wire this in....

There should be a 4 pin port on the brain to plug in a second sensor. I am trying to find info on installing a third and fourth sensor but no luck so far. I am guessing 2-4 all have to share the same input and have diodes on them.

Pyrofallout's last post is correct.
