NAMZ (2012-Up) HONDA Trailer 5/4 Combo Isolator (Includes Bike Side Harness)

What This Part Actually Does

This NAMZ isolator is designed for 2012+ Honda Goldwing (Gullwing) models and handles trailer lighting safely.

Key functions:

• Converts 5-wire bike signals → 4-wire trailer output
• Pulls power directly from the battery, not your bike’s signal module
• Uses internal relays to:
  • Read brake / turn / running light signals
  • Send them to the trailer without stressing OEM electronics
• Includes bike-side harness → no cutting/splicing required

👉 Why it matters: Without an isolator, adding a trailer can overload your bike’s turn signal module (which is expensive to replace).

Key Features:

• Fitment: Honda Goldwing 2012–present
• Output: 4-flat trailer connector (standard small trailer plug)
• Input: 5-wire motorcycle system (separate brake/turn signals)
• Protection: Prevents electrical overload of OEM system
• Install: Plug-and-play harness included
