Product Overview
Upgrade your Peterbilt 589 or 567’s lighting the right way with the JW Speaker 9600 plug-and-play harness adapter. It’s the missing link that makes premium LED headlights a seamless, stress-free upgrade for your next-generation Peterbilt truck! Early Peterbilt 589 owners discovered that the new factory wiring (with fender-mounted DRL/turn signals) wasn’t compatible with existing Peterbilt 389 aftermarket LED headlights. The JW Speaker 589/567 harness (SKU: JW-3272531) is the solution. This adapter connects JW Speaker Model 9600 LED pod headlights directly to the 2024+ Peterbilt 589 or 567’s wiring, eliminating the need to cut or splice wires. It’s an OEM-quality, plug-and-play harness designed specifically for the unique electrical setup of the 589 series.
The JW Speaker 9600 adapter harness for 2024+ Peterbilt 589/567 features OEM-style Deutsch connectors on each end, ensuring a secure, weatherproof link between the new LED headlight and the truck’s factory wiring. This harness maintains all functions (DRL, high/low beam, turn signal, marker light) with no modifications to your truck’s wiring. Built with durable materials and proper seals, it stands up to harsh road conditions while preserving your vehicle’s electrical warranty.
Key Features & Benefits
-
Plug & Play Installation: No modifications required – simply plug the harness into your JW Speaker 9600 headlight and the truck’s factory connector for a hassle-free setup. This harness is specifically engineered for Peterbilt 589 and late-model 567 trucks (2024+), matching the new wiring configuration for the fender-mounted DRL/turn signals.
-
Model-Specific Design: Unlike generic solutions, this harness is made by J.W. Speaker to fit Peterbilt 567 & 589 (2024 and newer) exactly. It uses the correct Deutsch DT 8-pin connectors as found on the 589’s OEM harness and the 9600 lamp, ensuring factory-like fit and reliability.
-
No More “Frankenstein” Wiring: Forget about cutting and splicing different harnesses together – this adapter harness preserves your truck’s wiring integrity. All headlight functions (high beam, low beam, daytime running light, turn signal, side marker) are routed properly through one clean plug-in harness. You get full functionality without any wiring headaches or errors.
-
Durable & Weatherproof: Built to OEM standards, the harness features automotive-grade wiring and sealed connectors to withstand vibration, moisture, dirt, and temperature extremes.

Essential for 589 LED Upgrades: If you’re upgrading a new Peterbilt 589 (or 2024+ 567) with JW Speaker 9600 heated LED headlights, this harness is required to make it truly plug-and-play. It bridges the gap between the JW Speaker 9600’s connector and the 589’s updated wiring, saving you time and ensuring a correct install. (Note: Older Peterbilt models like 388/389 use a different harness and do not require this adapter.)
Performance / Compatibility / Use-Case
Upgrading to modern LED headlights should be easy, not a wiring project. This Peterbilt 589 harness adapter takes the complexity out of the equation. It was developed to answer the demand from 589 owners who found no plug-in options for aftermarket headlights – until now. With this harness:
-
Installation is Simplified: Anyone can plug in the connectors – no special tools or electrical knowledge needed. The harness snaps into place securely, just like factory equipment.
-
All Functions Work Seamlessly: Your new JW Speaker 9600 headlights will operate exactly as intended – high beam, low beam, DRL halo, turn signals, and marker lights all function correctly through the adapter. There are no warning lights or compatibility issues since it’s designed for the truck’s electrical system.

Maintain Resale and Warranty: Because you’re not hacking into the wiring, you maintain the integrity of your truck. The harness ensures your upgrade looks and behaves like stock, which is better for maintenance and resale value.)
