i plan to buy a spare port hide the original and put a live feed into the new one so it buggers theyre computer up when they try to recode a key!!
Until one of the mechanics blows their computer up because they forgot that you had moved the original and doctored the replacement. Interesting to see how that would pan out. Probably best to just leave the replacement without wires.
Ford are renowned for skimping on wire in their wiring harnesses, sometimes not even allowing enough slack to remove components to allow for easier disconnecting, so moving the OBD port will be quite a carry on. If you have to extend wires, you might as well extend them with enough wire to locate the OBD port under the dash on the passenger side.
Thieves like this rely on speed of execution, so interrupting this is a positive, especially when the alarm continues to sound after they expect it to be switched off.
