New Z32 Power Transistor (PTU) sub harness. (Series 2 Power Transistor Unit Adapter Harness)
This sub harness was part of the recall on the earlier style PTUs and allows the new style updated PTU to be plugged into a earlier style EFI harness.
This sub harness is very prone to problems with corrosion int he connections and can't be purchased individually from Nissan. Symptoms are cylinders dropping, sometimes in and out, shaking at idle, very poor performance.
