Plug-in power, ground, and ignition harness for 2024+ Harley-Davidson® motorcycles. Connects directly to the P&A connector under the seat.
The Cicada Audio 24HDPA is a universal power/ground/ignition harness for 2024+ Harley-Davidson motorcycles – plugs directly into the factory P&A (Parts & Accessories) connector under the seat to provide switched ignition power, ground, and accessory power without cutting or splicing the factory wiring.
The P&A connector under the seat on 2024+ H-D motorcycles is a factory-provided accessory interface that delivers switched ignition power and ground through a standardised plug. The 24HDPA connects to that plug directly, providing a clean, switched power and ignition signal for accessories that need to power up and down with the bike – DSP processors, relays for multi-amplifier remote turn-on, and other accessory hardware that needs ignition-referenced power rather than a direct battery connection.
Who This Is For
Builders on 2024+ Harley-Davidson motorcycles who need switched ignition power and ground for audio accessories – particularly for powering DSPs, relays, or auxiliary modules without tapping the factory harness directly. The 24HDPA is the clean alternative to wiring into the factory loom for low-current accessory power needs.
What This Is Best For
- Switched ignition power for DSPs and relays – provides ignition-referenced switched power so connected devices turn on and off with the bike, avoiding battery drain.
- No factory harness modification – plugs directly into the factory P&A connector; no cutting, splicing, or tapping required.
- Clean 2024+ builds – keeps accessory wiring separate from the main power run, maintaining a tidy installation and factory-level harness integrity.
What's in the 24HDPA
A compact harness with a plug that mates directly to the factory Parts & Accessories (P&A) connector under the seat on 2024+ Harley-Davidson motorcycles. Provides power, ground, and switched ignition outputs for connecting audio accessories and relay modules without modifying the factory wiring. On the road: what you hang off this harness comes up with the ignition and goes down with it, so it is not quietly drawing on the battery while the bike is parked.
