Specs At A Glance

Good To Know

Q: Will this harness adapter fit my truck? A: Fit depends on the radio connector used in your specific Peterbilt or Freightliner model, so check the factory plug against the 16 pin ISO pattern before ordering.

Q: Do I need to cut factory wiring to use it? A: The adapter is designed to plug between the aftermarket radio and the factory connector, so no cutting of the original loom is normally required.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
