EN-46999-20 Active Fuel Management Tester Tool Harness

EN-46999-20 is an adapter harness that allows the use of EN-46999 AFM Tester on Gen V V6 engines. The Gen V LOMA has a different connector and wiring than Gen IV V8. EN-46999-20 has both Power and Resistance leads. The Resistance lead is connected between EN-46999 and the engine connector to measure the resistance of the individual LOMA solenoids before any disassembly, and the Power lead is used between EN-46999 and the LOMA on-vehicle to listen for activation, and off-vehicle to conduct an air test of the solenoids.
