Yes- You can get limited functionality without the controller. Essentially the siren is in hands free mode and you scroll through the tones with a user supplied momentary switch or the horn ring. Air Horn is also available as a secondary momentary button.
You lose the function of the rotary switch in this setup. I thought I figured out a way to simulate that, but I can't find my drawings. This at least gives you basic functionality with two momentarys button and an on/off switch.
In addition to these connections you still need to connect the speaker out wires and the main power and ground (use a relay or a switch that can handle 20 amps). For the speakers you should have 4 total wires in two 4 pin plugs. That means each plug will have two blanks. Some models have "straight inline" 4 pin plugs vs. these square ones, pinout is the same essentially.
