hi a friend of mine has asked me to help put a "cheap alarm" on his bike (not really for security more deterrent because of the little feckers kids messing at the bike when he parks it at his mam's flats)
well as i dont know much about electrics i still said yes
it just has 3 wires red, black, blue
so the red = battery+ the black = battery- the blue = ??????
any help on where this goes
thanks in advance
The uninformed about the specific unit you are using answer is: Red to constant power, Black to ground, and Blue to switched power. This is assuming the manufacturer is following accepted conventions regarding power and ground wire colors. The Blue wire (again, going by the earlier assumption) is the deactivate signal when the key is turned on.
I would, however, recommend ferreting out installation instructions before acting on "uninformed about the unit you are using" opinions ... regardless of the source. Yeah, even me. After all, it won't be me paying for a new unit when it's smoked by hooking it up wrong!
If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

I was also thinking blue might be the antenna. Definitely don't want to hook that to any type of power source if it is!
it has an antenna aswell as the 3 coloured wires and comes with a remote lock/unlock unit
i have tried to contact the supplier about instructions as the page (instruction) he got with the alarm does not make any sense at all
its just the words are all jumbled up
but now i've only found out he paid like £10 for it inc delivery from china or similar place
i have tried it with just the 2 (black,red) wires on a battery and it works
so which only leaves me thinking maybe it's the ground/earth wire, since it comes with remote and does not have immobilizer ect..
so if it turns out to be the ground/earth wire
where would the best place to put it
