Performance / Compatibility / Use-Case
It’s not the truck, it’s the adapter. Say good riddance to the idea of upgrading your old Peterbilt with this wire harness adapter from J. W. Speaker. Featuring both a plug-and-play installation and a quality-made design, this wire harness helps your mind to rest easy on the road, knowing that your Model 9600 headlights will continue to function properly and guarantee visibility in all kinds of weather and hazardous conditions.
Installation / Fitment / Technical Details
J.W. Speaker no longer includes harnesses with their Model 9600 headlights. Without the right harness, the headlight will not connect to your truck’s wiring. The 3271081 harness bridges the 6‑pin Deutsch DT06‑6S connector on the headlight to the factory wiring on 388/389/567 trucks. Each harness weighs only 0.40 lbs (0.18 kg) and is built with automotive‑grade wiring and sealed connectors to withstand vibration, moisture and road debris. Installation simply requires attaching the harness to the back of the headlamp and plugging it into the vehicle harness—no cutting or splicing needed.
