Toad Alarm

[Drk_red_Mk5]

i have just got hold of a toad Ai606 alarm.ive installed it all but am having problems with the siren.everything else works.the previous owner snipped the connector off hte end of the siren and the 4black wires that go to it for some reason an i need to reconnet them.i have a wiring diagram but no combination seems to work??

 

i know that one colour connects to a good ground source an another conneeccts to the wire that goes to the indicator input.if anyone could find out which ones they are and let me know it would save a lot of headache!

 

thanks.
