MOONSMC® 2025-Current M8 Softail Gen2 Rear Fender Wire Harness

⚠️ 2025-Current Softail M8 Gen2 Only
This harness is designed specifically for the updated rear lighting system found on compatible 2025-current Softail M8 models. It is not the correct harness for 2018-2024 Softail M8 applications.

⚡ Correct Rear Lighting Signal Routing
Provides the proper power and turn signal routing for compatible MOONSMC® rear lighting upgrades, including the V4 Tail Light and MoonPods.

🔌 Plug-and-Play Design
Designed for a clean installation on compatible 2025-current Softail M8 Gen2 models without cutting or splicing the factory rear fender wiring.

🏍️ Built for Modern Softail M8 Lighting Upgrades
Gives riders a clean way to add compatible aftermarket rear LED lighting while retaining the proper wiring path for running, brake, and turn signal functions.

⚡ 2025-Current Softail M8 LED Lighting Load Equalizer
When upgrading a 2025-current Softail M8 to compatible LED tail lights or turn signals, you will also need the MOONSMC® Softail M8 2025-Current LED Lighting Load Equalizer.

The factory electrical system monitors lighting load, and the lower power draw of LED lighting can cause hyper-flash, bulb-out warnings, signal issues, or lighting fault codes. The load equalizer provides the electrical load correction needed for the bike to properly recognize the LED lighting setup.

🔌 Use the Earlier Softail M8 Rear Fender Harness
If your bike is a 2018-2024 Softail M8, this Gen2 harness is not the correct version. Use our earlier MOONSMC® Softail M8 Rear Fender Wire Harness for compatible 2018-2024 rear lighting applications.
