Frequently Asked Questions
Does the Harness Include Mounting Hardware for the Relay or Switch?
No; the harness does not include mounting hardware for the relay or switch. It notes mounting options are user-supplied, while relay specifications (power relay, blade fuse, 12V, 12AWG) are provided for liberated installation.
Can the Switch Illuminate When the Lights Are Off?
Yes; a faint glow from the switch illumination can remain when lights are off, allowing stealthy navigation of controls while preserving freedom. Verify light bar compatibility and wiring configuration to prevent phantom power or unwanted LED backfeed.
Is the Wiring Harness Expandable for Multiple Light Bars?
Yes; the harness offers expandable options for additional bars if power and grounding meet wiring compatibility limits. Users seeking liberation should verify total amperage, relay capacity, fuse sizing, and connector types before chaining multiple light bars.
What Is the Maximum Amperage the Relay Can Handle?
The relay amperage capacity is typically 30A, freeing users to design boldly; electrical load considerations require verifying combined lamp draw, fuse rating, and wiring gauge to guarantee safe, liberated customization and prevent overloads or failures.
Are Replacement Fuses or Connectors Available Separately?
Who wants dependency? Yes, replacement fuses and various connector types are available separately; users should check fuse compatibility with the blade fuse rating and source matching pin or plug connector types to retain freedom and reliable, independent repairs.
