Need help with backup battery siren pinouts

[turbo_slug]

i have a backup battery siren w/ no documentation.


it has 4 wires. there's red, black, blue, and white. i assume red is +12v and black is chassis ground but what is the blue and white wires? is one of them for positive trigger and the other one is negative trigger? anyone know which is which?

Usually the white wire is for positive trigger. Try it on your battery. Ground it with the black wire, give red power, then touch the white to power. If it doesn't work, touch the blue to power.
