(888) 312-8812 Login SignupElectrical problems around the engine can spread quickly when the main harness has aged, rubbed through, or lost connector reliability. The Mack Engine Wiring Harness gives MP7 and MP10 MRU applications a new OEM engine-side harness for broader wiring service. Its loom assembly supports the main engine electrical routing instead of limiting the repair to one branch lead or small connector. At 15 pounds, the Mack 21602419 is a full harness assembly built for larger engine electrical work on Mack trucks. For MRU service bays dealing with multiple harness concerns, this part provides the correct engine wiring assembly in one replacement unit.
This harness is custom-built for your vehicle, so we need to make sure we get it right the first time!
