This toggle switch is an aftermarket replacement for the on/off control of the Jake brake (engine compression brake) in Peterbilt trucks.
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 directly replaces the original equipment part number 16‑03399, fitting the dash cutout with the correct electrical terminals. Over time, the switch can wear out or develop internal corrosion, causing the engine brake to become inoperative or intermittent. Replacing it restores reliable control of the exhaust brake, which is critical for slowing the vehicle on steep grades without overheating the service brakes.
