factory alarm disarm/arm wires?

Remote starter Autopage 850 lcd added to a 1998 Chevrolet Suburban.  The factory remote, when unlocking the vehicle, also turns on the interior dome light for about 30 seconds and when locking the vehicle is turns it off within 3 or so seconds and honks the horn once. Is there a wire and/or wires that need to be connected for this to function with the aftermarket alarm for this vehicle? Could this feature be intergrated with an after market alarm? I would really appreciate any information. Gage

only disarm, it should be in the door boot or at the bcm under the dash behind the metal shroud that you need to remove 4 10mm nuts from. it's a light green, as far as re-arm, it will only work if you lock the doors with the r/s remote witht he door open. then when you shut the door the trucks alarm takes over.

Thank you for the prompt reply.Gage
