viper 5901 passive arm

I have a 08 Chevy Avalanche with the Viper 5901 installed using an Idatalink ADS-DLSL-GM3 interface.  I prefer the passive arm feature (usually forget to lock my truck way more than leaving keys in it).  So I had the installer add a pin switch to the tailgate for use as a trunk input thinking it would prevent the passive arm while I was getting groceries out of the back.  Am I wrong in thinking it should work that way (installer said it should)?  There are also a few other gremlins that maybe related too.  The hood input is intermittent on shutting down the remote start or preventing it from starting.  The doors are intermittent on whether or not they activate the passive arming.  The new tailgate switch never prevents passive arming.  But all these inputs work 100% on setting off the alarm when activated.  I am patiently working with the installer (DEI authorized), but it is not going well, so I was looking for some tips that might help.

Thanks,

I believe IDatalink's just came out with D2D compatible modules, but mine is not (direct wired).

Good point on changing the tie in point to the neg door trigger, provided the positive one was used already on the door and that the system will sense both inputs being in use.  Though you would think that getting things out of the trunk would have been a consideration on the passive arm feature.

Thanks for the input.

With remote start alarm systems, do these inputs typically go through the canbus interface module or just to the 5901?  Also, any suggestions on the intermittent door (for passive arm) and hood (for stopping remote start) inputs?

Thanks,

Thanks.  I am wondering if this module maybe causing my intermittent gremlins.  Doesn't make sense that they trigger that alarm 100% of the time, but fail on remote start disable or passive arm.

Hoping the rain quits so I can check out some of these items.

True, but think the possibility of having a warranty through the installer is rapidly disentigrating anyway.  Doesn't appear that all installers have to be qualified to be an authorized dealer.  So may have no choice.  I don't have a problem working with electronics, but my back will not let me stay under the dash for long.  The easiest/cheapest thing for me might be to just grab a Xpresskit DLPK module (since it is D2D) and replace the Idatalink module.
