This is a wiring harness for Thieman liftgate systems, commonly used on medium- and heavy-duty trucks and trailers.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It carries electrical power and signals for components such as tail lights, control switches, or actuators. Over time, exposure to road grime, moisture, and vibration can cause shorts or opens, requiring replacement to keep the liftgate operating safely and reliably. It is typically sold as a direct-fit replacement for specific Thieman liftgate configurations.
