Hi can anyone tell me what a NEGATIVE TRIGGER is and a NEGATIVE OUTPUT cheers paul.

Let me guess you are trying to connect the door locks?You might have to wire relays to switch the positive pulse to a negative pulse.I have to try to dig up my papers on how to wire the relays.

Hi tech thanks for reply i am trying to wire a microwave bubble to car c70 converible it has 4 wires red, black,blue,green. red to +12 volt and red on peizo sounder,green to black on peizo sounder,black to negative output,blue to negative trigger input.

Sorry but im not really sure what you are trying to hook up.So I can't help you all that much at the moment.I might not be understanding the translation good.

ok thanks anyway paul.
