2020 Ram Rebel 1500, Shift Interrupt

Looking for advice on which wires to interrupt so the shifter can not be moved out of park while running. Would like to add a secondary immobilizer or hidden switch that won't allow shifting if a thief clones key fob. I've seen a few videos of security systems that were added and when armed the shifter does not let the vehicle out of park. Anyone have experience with this? My current truck is 2020 Ram Rebel 1500 if anyone has a wiring diagram. I did not find one in the vehicle wiring diagram section. Thanks.Steve G

You may have already found a solution, but if not, have a look at this: https://www.ramtrucks.com/BodyBuilder/service/Image?imageId=MtQrP%2FFqLY5r%2Fest8MtGjGgHzAHGUTU0WB3rWuqSY7YmQ2vEhuBWBB50ujfcHjlM%0A Apparently there's a brown/yellow wire that can be interrupted.
