Today we’re installing and testing the Lynx Performance Locker Sensor Bypass Harness for the 2018+ Jeep Wrangler JL and Gladiator JT. Whether you're dealing with that dreaded "Service Axle Locker" warning or want dependable locker engagement in the harshest conditions, this harness is exactly what you need.
Why It Matters
Jeep’s factory locker position sensors often fail, leaving you unable to lock your axles even if the mechanical locker is working fine. Replacement sensors and axles are on backorder, and dealerships sometimes require full axle replacements. The Lynx bypass harness solves this:
Direct-fit for 2018–2024 Wrangler JL & 2020–2024 Gladiator JT — no mods, no tools
Plug-and-play, waterproof, and durable – perfect for mud, water, and trails
Simulates position sensor signals — restores proper engagement and suppresses dash errors
Install Time: Lee than 1 Hour
Perfect for beginners! We'll walk through the installation step-by-step.
Who's It For?
Jeeps stuck with inoperative lockers due to failing sensors
Off‑road adventurers wanting confident locker engagement
Anyone looking to avoid dealer delays and expensive axle swaps
What’s Included:
1x Lynx Locker Sensor Bypass Harness (for either front or rear Jeep axle)
Pros:
Instant remedy for sensor failures
Maintains onboard dash/switch feedback
Rugged, weather-sealed design
Note:
This harness does not enable lockers in 2‑High or 4‑High—it simply bypasses the faulty sensor to preserve factory functionality in 4‑Low as intended.
Final Verdict:
A must-have upgrade for any JL/JT owner battling sensor issues—gives your lockers back their mojo without wiring woes or waiting on parts.
