Wondering if anyone has a siren controller (and siren) in their AHB. I'd like to install one in my '89 Diplomat and would appreciate any info on which box you're using, and how it's wired up. I want one for shows, etc.
I've seen guys use the Federal Signal PA300 controllers for shows - pretty straightforward wiring through the existing radio harness if your Diplomat still has the police wiring intact.
