The switch has to be wired in along with all the wires under the dash, in wich case you must have 95% of the wiring to make the engine run.

if its an early ford fiesta the cut off is not in the ecu, the ecu does not open the central locking, if you know what your doing you do not need all the car wiring!
ive worked for ford for 20 years so kind of know what im on about!
