Ok boys, I need some help. I just bought a whelen 295hfsa6 siren and need help finding out exactly what to get and where to get it. For right now, I want to hook it up to a separate 12v power supply and not in my car. So, this installation will have nothing to do with the car for the time being. I have the 12 pin harness, but no cords are attached.


My friend who is very good with electronics is helping me install, but I need to have all the necessary parts first. I would love if someone could tell me exactly what to get, and where to get it to get this thing tested.

i am dealing with one of these for a guy - and I am trying to learn myself


he had an "electronics" guy wire it - who did so with relays - my guess - since it was not a matrix relay bar - the relays were put in as this is a low current box. Now I am just trying to figure out how to get power to the slide switch - or to see if it is blown internally - also - need to see if there is a way to get the last button to lock and not be a momentary

I find out how it works. I got all the proper gauge wire, did some saudering, and got it to work. I attached a cigarette plug for power in my car

Good lord. If you think running that off a cig plug is a good idea.... STOP NOW and take it to someone who knows what they're doing before your car goes up in a fireball.

Well it wasn't my idea and it is pretty unnecessary but why do you think its dangerous? The plug has the proper amps and voltage

Because you're trying to run a switchbox off a plug receptacle rated at 10-20 amps. If you end up using the siren, with all the lights, you're going to overload the 16 ga wire going to the cig plug in the vehicle. Hence, burning wires.

The last button is a momentary with the S6 series...its ment for gun locks and such, if you want it to work as a normal switch you will have to physicaly replace it.

Default is momentary, but it will can also be timed for 8 sec. or a latch on-latch off (similar to the rest of the push buttons) or flash 400ms-on-400ms-off.

I have the 295 powered on by a cigarette plug rated a 20 amps I believe. I have a 20 amp fuse in the cigarette plug, and a 20 amp fuse the + power wire. I don't use the switch box, but even if I did, i thought thats why those 10gauge red wires were there?? Meaning the red wires can just go to the battery for power for the switch box while the siren itself uses the cigarette plug. The only thing I worry about is the cigarette "hole" can constantly handle the electricity. Theres no markings on it that say "12v" but i assume it should be fine.

But th wires going to that plug are NOT as big as the power wires going to the Siren. You should be ok but over time trying to pull that much power might end badly..
