U, W, L, N, This harness adapts previously essential J 34730-380
Injector Load Tester for use on the 3400, 3100, and 3.4L DOHC Engines.
In the event of a misfire, the load tester is used to diagnose the
control module's output signal to each injector. This adapter
interfaces J 34730-380 Load Tester to the engine wiring harness. With
the load tester connected, LED's on the tester will flash during engine
cranking when the PCM is producing an output signal.
