Morning all, I am in the middle of a install where I would like to use a whelen SLSA6 siren to control the operation of a whelen howler. I already programmed one of the 6 push buttons to momentary for triggering the howler. What I am wanting to do is use a 5 pin relay to complete the circuit between wires 7 and 14 in the howler harness. Here is a pic of what I am trying to achieve. My question is will it work? The siren is positive switched and the howler just needs the 2 wires to be connected for operation from what I can see. Any thoughts or other ways to go about it? Or how you may have done it with that siren?. I am trying to avoid using random push buttons. Thank you.
