R33 alarm removal

[DONO]

So I’ve been trying to remove an alarm, as it was going off randomly, and the remote has had it etc just wanted it removed.

I’ve located the unit that is the alarm system itself.
My question is;

*is everything meant to plug right into a stock/factory piece that isn’t there?* I wouldn’t imagine so, but some of the plugs that went into the alarm look uncut/factory.

I’ll attach photos with the post for reference.

the alarm is marked with the label ‘warlock’ and a couple serial numbers but I couldn’t find any information on it, (was hoping for a diagram or even their website to ask them) so I assume maybe it’s a cheap eBay copy or something, and probably old.

Any information helps, whether you know if it’s meant to reconnect to a particular part, or have a diagram of individual wiring, knowing the company, anything at all helps thanks.
