NAMZ Throttle-By-Wire Extension Harness 18 Inch for 2014-2015 Harley-Davidson FLH FLT Touring
Taller bars on a 2014-2015 Touring model are a serious upgrade — and this kit makes sure the throttle-by-wire system keeps up without a fight. The true plug-and-play design gets the TBW circuit sorted quickly and cleanly, so the focus stays on the ride and not the wiring bay.
Key Features
- True plug-and-play design — no de-pinning or terminal transfer required, unlike NTBW-X series kits
- Adds 18 inches of length over the OEM throttle-by-wire harness — engineered specifically for taller handlebar installations
- Designed and tested to extend the TBW circuit without causing harm or interference to the motorcycle’s ECM or CAN bus system
- OEM color-coded wires for straightforward, accurate connection during installation
- Does NOT fit CVO/SE models — fitment is for standard (non-CVO) FLH and FLT Touring models only
- Made in the U.S.A.
Technical Specifications
- Extension Length: 18 inches longer than OEM
- Installation Type: Plug-and-play (connector kit required — sold separately as NTBW-CK)
- Wire Type: OEM color-coded
- System Compatibility: Harley-Davidson Electronic Throttle Control (TBW/ETC), 2014-2015 FLH/FLT
- Country of Origin: United States
Fitment Notes
- Fits 2014-2015 non-CVO Harley-Davidson FLH and FLT Touring models including Street Glide, Road Glide, Road King, Electra Glide/Ultra, Tri-Glide, and Freewheeler variants
- Does NOT fit CVO/SE models (e.g. FLHXSE Street Glide CVO, FLHTCUSE Ultra Classic CVO) — a different extension is required for CVO applications
- The NTBW-CK connector kit must be purchased separately — this harness does not include connectors and is not functional without them
- This kit covers the TBW circuit only — the standard handlebar switch extension (NAMZ NHCX-J series for 2014+ CAN bus models) must also be purchased separately for a complete handlebar swap
- This product does not fit models with hardwired (non-connector) TBW harnesses
- For 2008-2013 TBW Touring models, see the NAMZ NTBW-X series instead
