Modern motorcycles with CAN-bus systems monitor the electrical load on their circuits. Factory incandescent turn signal bulbs draw significant current. When you replace them with LED signals, the reduced load can trigger diagnostic trouble codes in the Body Control Module (BCM). This adapter adds the correct resistance to maintain the expected electrical load, preventing error codes and warning lights.
You need one adapter for each turn signal location you are converting. Most motorcycles have four turn signal locations (front left, front right, rear left, rear right), so you would typically need two kits of this product. Each kit includes one adapter with a single resistor and two Posi-Tap connectors.
No soldering is required. This adapter uses Posi-Tap connectors that pierce the insulation of your factory wiring, creating a secure electrical connection without cutting wires or using a soldering iron. This makes installation quick, clean, and reversible.
This adapter is compatible with: Harley-Davidson Softail (2011-2024), Dyna (2012-2017), FLT/Touring (2014-2024), Trike (2014-2025), and XL Sportster (2014-2022). For Indian motorcycles, it works with Chief, Springfield, Chieftain, Roadmaster, and Scout models (2014-2024). Compatibility requires that you are removing the original turn signals.
Yes, this load resistor adapter works universally with any LED turn signal conversion. The adapter maintains the correct electrical load for your CAN-bus system, regardless of which LED turn signal manufacturer you choose. It's designed to work with the factory wiring on compatible models.
The 200 Ohm, 2-watt resistor simulates the electrical load of factory turn signal bulbs. By providing this resistance in the circuit where the old signals were, your motorcycle's BCM sees the same electrical signature it expects, preventing error codes and keeping your check engine light off.
No, this adapter is specifically designed for use when removing factory turn signals and converting to aftermarket LED signals. If you keep the original turn signals installed, the adapter is not needed and will not provide any benefit.
Posi-Tap connectors are self-piercing taps that require no tools beyond a basic connector or pliers. Locate your factory turn signal wiring, position the Posi-Tap connector over the wire insulation at the designated point, and press or squeeze firmly until you feel a click or resistance, indicating the connector has pierced the wire and made contact. Consult the included instructions for detailed guidance.

The Custom Dynamics CAN-bus adapter is an essential component for riders upgrading to modern LED turn signals on CAN-bus equipped models. When removing factory turn signals from Harley-Davidson Softail, Dyna, Touring, Trike, Sportster models or Indian Chief series motorcycles, the motorcycle's Body Control Module (BCM) can trigger diagnostic trouble codes due to the reduced electrical load of LED signals compared to traditional incandescent bulbs.
This intelligent adapter solves that problem by adding the correct load resistance to fool the BCM into thinking the original turn signals are still in place. Each kit includes a 200 Ohm, 2-watt resistor and two Posi-Tap connectors, allowing for quick and clean installation without soldering or cutting factory wiring.
Simply install one adapter per turn signal location to eliminate error codes and enjoy seamless LED turn signal operation.
Whether you're building a custom cafe racer, upgrading your classic motorcycle, or modernizing your touring rig, this CAN-bus load resistor is the professional solution for turn signal conversion. Compatible with 2011-2024 Harley-Davidson models and 2014-2024 Indian motorcycles when OEM signals are removed.
