'00 Chrysler T & C Remote Start Issue

I have been blessed with the job of installing Bulldog remote starters in three Chrysler Town and Country minivans (one 2000 and two 2003).  I began with my wife's 2000 (I will do the others after I finish this one).  I purchased the T-Harness to make the job easier, however, the installation has been a failure.  The unit turns on the ignition, but emits a loud buzzing from the box and doesnt start the vehicle.  I am led to believe that the van must have a security feature that I cant locate.  On the bulldog website, a dk grn/white wire is indicated for the security system but I have been unable to locate this wire physically or in the Hayne's wiring diagrams. 

Any help on this issue will be appreciated. 

What do you need to know i have just completed one on a 03 T and C. As for the 2000 you can get the wire diagram off the 12 volt website here is the link:

As for the 2003 i can tell you more as you need

Well, I finally located the wire and now the unit functions, however this just allows the vehicle to start.  It doesnt bypass the vehicle alarm system which will go off even though the van will start with the bulldog. 

The temp solution right now is to use the factory remote to unlock the doors, use the remote start and then relock the doors.  Now my wife can stay out of the cold but with the minor inconvenience. 

Hopefully the install of the 2003 units will be easier.  I see that I will need a transponder bypass unit.  If I have any problems with that install, I will let you know.
