Alarm Wiring & Random Cable

[Primal_Concrete_Micra]

Was cleaning up my engine bay earlier and found what seems to be part of an alarm system, the wires on it have been cut, can this easily be wired back up to become a working alarm or does it need other parts installing?!

Also just below this i found a wire going into the bodywork of the engine bay, not sure where it went to or what its for, any ideas?

The alarm will probably need some sort of control unit so it knows when to go off, activate/deactivate, flash the indicators etc. It's probably best to rip that siren out and just buy a whole new kit

Agree, also that other wire is an earth strap and should attach to something on the engine.

cheers, ya reckon the earth strap could be from the alarm also, or should i try and find somewhere it came from?

That earth strap clips on to some stupid little metal thing on top of the gearbox towards the back.

The clip is held on by one of the gearbox bolts. can be easily found if you round your hand along the gearbox/engine join and feel around some of the bolts.

That looks like a simple cheapo alarm. 1 wire to positive, one to negative and one to interior light.

So when does it know to go off and how would you deactivate it. No alarms are that simple!

 

[ollyc98]

they usually have a hidden switch and a 30 second delay.

na that's crap. There still needs to be a control unit that runs everything!

Mine had the control unit built into the siren, maybe not then, rip it out and get a CAT1 installed anyway.
