Does anyone have the caravan alarm system which is factory fitted in a swift corniche which is made by "plug in system". I contacted swift regards the alarm and they have given me the name of the compnay who supply the system, i take it that the company just sell alarms to swift for them to fit into the caravans in the factory. But i am trying to find out more info about codes for this alarm. There is a black box under the seating area with "plug in system" marked on it.
