Hi guys , question regards alarm control . I have a 97 s14a , the vehicle came with no fobs . I understand that with each alarm control unit a master fob is coded to the c.u and is required when coding additional fobs . I have the chance to purchase a alarm control unit and the master fob coded to the unit , is this a case of just plug and play or does the alarm control unit need coded to the car . Cheers in advance
