How do you connect an alarm on a Ford Focus?

You might have to take it in to have it put in. They would know what to do to fix it.

Disconnect the positive battery cable by opening the hood. Attach the start disable relay to the starter wire and connect the power lock module to the lock relay. Make a small hole and place a LED light on a dash board. Connect the siren wires to the alarm control module.
