Frequently Asked Questions
Will my trailer lights still work without this isolator?
Yes, but the isolator prevents electrical interference, flickering lights, and battery drain issues that occur when trailer circuits share power with the motorcycle.
Do I need this if my trailer is LED-equipped?
LED trailers especially benefit from isolation to prevent voltage spikes and flickering. Isolators are strongly recommended for any trailer setup.
Is this a direct plug-and-play install?
Installation requires basic electrical knowledge and connection to your existing trailer harness. Many riders have a shop handle the wiring to ensure proper grounding and isolation.
Does this fit my 2013 or older Harley?
No — this isolator is for 2014-up FLHTCUTGSE and 2015-up FLTRT models only. Earlier Harley models use different wiring harness connectors.
