how many wires have you got!
i'm not 100% sure but your alarm may have wires like theses
this is normaly the case with most alarms!
red wire - +12v
balck wire - negative / earth
brown wire - negative trigger input ...... like untrasonics or bonnet / door switch.........
yellow wire - negative trigger output when alarm is armed! this switches the untrasonics on........
orange wire - negative trigger output when alarm is sounding.... connects to pager! or internal siren.......
most alarms have wiring like that........
some can have orange or gray wires which connect tothe indicators...... it all depends on what make model it is etc etc......... this may help you.........
i'll have a search on the net and see if i can find anything!
