Alright. I got the Autopage 750LCD in the truck with the remote start (01 2500HD Diesel). BUT... If I manually lock the doors and THEN get out of the truck, I can set the factory horn alarm off by hitting the unlock button. Ideas?

you need to tap the light green wire in the far right plug of the bcm under the steering column . you connect the pink wire from the alarm brain and you will need to go into the program mode and switch the output of the pink wire to factory disarm signal.
