Kill Switch

[Interested DIYer]

I am thinking about hiding a switch that can be thrown to break the output from the fuse in the F11 spot in the Internal Power Distribution Center (the "IPDC", which is under the steering wheel) to the Under-hood Power Distribution Center (the "UPDC") . If I do, I'd use the same size wire that is already there, and the total length of the wire would not be more than 10', with the switch in the middle of it and hidden somewhere. I don't think I'd need anything else in that line but the wire and a switch, but you guys who know more about electronics than I do would have to tell me. It looks to me like the effect of breaking that circuit by throwing such a switch would be to render the run coil inoperative.

My intention is to make stealing my truck more difficult for the fob cloners (which I hear are in big business - mob theft on a large scale). I heard one story of a truck being taken from the midwest being found in a cargo container on the east coast just a day or two later. I have seen the Faraday pouches and know they work, but staying consistent in their use is a hassle.

Anyway, before I try this idea out, can anyone warn me away from some downside I am not seeing? (I already understand the downside of unintentionally throwing the switch "open" while driving). Wouldn't I avoid throwing any codes if I never "open" the switch while the ignition is on?

Has anyone bought the harness that plugs into the push button so you don't need to cut the red power wire on the factory one? Or is it part of the main dash harness?

Also, if the vehicle is started via OBD. Is this kill switch for the start button still effective?

Hello all, working on install of a vehicle tracker with 4G service on my 2021 1500 DT. 4 wire connection: DC+,DC-,ACC, and fuel pump shut off relay. This diagram appears to be the missing link to the install. Thanks
