NJSBYL Mirror Spot Light Override Harness for Ford F-150 & Super Duty (2015-2022) — Plug-and-Play, Keeps Spotlights On Above 6 mph

If your Ford F-150 or Super Duty tow mirrors shut off automatically above 6 mph, this plug-and-play override harness restores full manual control. Designed to work with the OEM spot lamp system, the module intercepts the factory connector so the spotlight stays active whenever you press the original button — whether the truck is in drive, parked, or turned off. It’s a compact, reversible install that uses factory-style connectors and corrosion-resistant sleeving.

How does this harness change spotlight behavior while driving?

The NJSBYL override harness prevents the factory speed-based shutoff and keeps mirror spotlights illuminated when the OEM switch is engaged. It works by inserting between the factory spot lamp control module and the vehicle harness so electrical logic that disables lights above 6 mph is bypassed.

• Maintains spotlight power once the OEM button is pressed
• Works with the vehicle in drive or park and even when the ignition is off
• Requires only one forward-facing mirror harness per truck
• Does not require permanent cutting or splicing of factory wiring

Will this fit my Ford F-150 or Super Duty and what models are supported?

The harness is built to match factory connectors on specific model years. It fits 2015–2020 Ford F-150, 2017–2020 F-150 Raptor, and 2017–2022 Ford F-250/F-350 Super Duty trucks equipped with OEM or properly retrofitted spot lamp systems and the factory spot lamp control module.

• Compatible with trucks that have the mirror, door harnesses, OEM spot lamp switch and control module
• Works with both factory spot lamps and many aftermarket/upgrade towing mirror lights
• If the truck lacks the factory control module, this harness will not function
• Check that your spot lamp module uses the green OEM connector pictured in installation guides

How difficult is installation and will it affect factory settings?

Installation is straightforward and intended as a plug-and-play upgrade: unplug the green connector at the spot lamp module on the driver-side dash, insert the NJSBYL harness inline, and secure as needed. The procedure preserves original wiring and aesthetics while keeping factory functions intact.

• No trimming, soldering, or special tools required
• Heat-resistant corrugated sleeve for durability and abrasion protection
• Reversible—remove the harness to restore stock wiring if desired
• Includes one harness per vehicle for front-facing mirror control

Who is this for: drivers who tow, off-road, or operate in low-visibility conditions and want continuous manual control of mirror spotlights. If you own a compatible Ford F-150, Raptor, or Super Duty and want your mirror spotlights available at any speed—without permanent wire changes—this NJSBYL speed override harness is a simple, OEM-friendly solution. Remember to turn the spotlight switch off manually when the truck is parked and you want the lights off.
