Hi i have a bulldog delux 500 remote starter and the output for the horn/siren is a negative wire. I have a siren from an alarm i had before and i am just wondering how can i wire it? In the manual it saysthat the wire is a negative 200ma output and should only be connected to the cars horn. How can i connect this siren? if i have to use a realy how do i wire it thx.
This negative horn output is actually a pulsed output and won't give you the expect result. It won't actually keep your siren sounding, it will pulse it. The best thing to do it connect it to the horn with a relay and you're done, since the remote starter will only honk it when locking/unlocking or starting.
