Harness diagram: Smith & Wesson Siren

Model 875.
When I removed this from a vehicle, I labeled all the wires but I think over time the labels fell off.
Can't find a diagram on line.
Any ideas?
Thanks!

how many wires are there? post a picture.

Battery charger ground clamp on siren. Touch each lead to the power clamp. You'll see what each one does.

that's just what I did

This siren went to 2 speakers. I wired one set of wires to a siren speaker, and used my Power Probe III to test the wires. I labeled the ground before I disconnected it. There was a red wire that I had marked hot. THEN there's a red wire with an inline fuse coming out of the back of the unit, not included in the harness. This didn't wire didn't bring power to the box. So anyway I got it to work on the bench.

There is a lot of information there and some pretty knowledgable fellows as well.

Keep the smoke inside if possible.
