Can you kindly elaborate it further?
There is another option.
Those cars which ran out of warranty, owners can add electronic switch with the key and it will cut the circuit to ecu (no key can be cloned).
Again dead easy but if there is an option of complete removal of OBD port then I guess nobody would go down the route of splicing wires.
