KC HiLiTES FLEX ERA Backup Wiring Harness with 40A Relay & 3-Position Rocker Switch (3-Pin DT)

Wire your FLEX ERA backup lighting the right way, with a purpose-built harness that adds a real relay and driver control.

This KC HiLiTES harness is designed to power FLEX ERA-style backup or reverse lighting through a 3-pin Deutsch DT connector, so you get a clean, weather-resistant plug instead of splicing bare wires. The built-in 40 amp relay protects your circuit and keeps voltage steady to the lights, while the included 3-position rocker switch lets you run the lights on, off, or tied to your reverse signal. It is aimed at anyone installing or replacing KC FLEX ERA backup lights who wants a factory-grade wiring solution.

• 40 AMP relay for stable, protected power delivery
• 3-position rocker switch for on / off / auto-with-reverse control
• 3-pin Deutsch DT connector for a sealed, plug-and-play light connection

Note: this harness is built around the 3-pin DT plug used by FLEX ERA backup lights — confirm your lights use the matching connector before ordering. Explore more lighting wiring and the full KC HiLiTES range.
