After market security system fitting into N15 pulsar

[Pete fly by nissan]

I am looking to install a after market security system with door lock and full engine lock out capabilities to my N15 pulsar LX which seems to have a factory fitted security system unit fitted and am a little put out as to how to go about the mod ,I am very professional and adapt about how I do things and as a trade qualified person , just wondering how I can get a after market security system unit to integrate or or to remove and replace it with the new unit from an eBay unit and has any one else had the same problem or queries on this same problem.??

You usually start with wiring diagrams and a good knowledge of car electrical systems.
