Wiring Specialties VG30 Wiring Harnesses are 100% brand new wiring harnesses composed of the highest quality materials and craftsmanship. Originally designed around the OEM harness, this implements all of the features and improvements Nissan made over the years, and then some. It is designed to accurately follow the OEM appearance, design, construction, and routing, making it a direct replacement for the stock EFI harness.

The EFI harness (this product) connects from the ECU to the gauge cluster, and all major engine components such as the injectors, PTU, coilpacks, temp sensors, CAS, MAF, and more. If you're also looking for the harness that connects to the transmission, alternator, and starter, check this link for the Alternator/Transmission harness options.

Please note: Some photos show the LHD version of the harness, but they are largely the same as RHD--the only real difference is the length of the branch at the firewall.

FAQs

• Will this fit my Z32? : This harness will fit any and all RHD Z32s. Certain models will have some leftover connectors as these are designed to fit such a wide variety of models.
• Which do I pick for an AT to MT swap car? : As far as the EFI harness is concerned, your car is a MT. You CAN still use an AT harness on a MT car, you'll just have one extra connector. Your starter inhibitor and reverse lights are handled by the Alternator/Transmission harness, which is a separate harness.
• Which CAS/injector style do I select? : While we can determine what your car shipped with when it was new by year/model, these cars are 30 years old and most have passed through several owners now. If you don't know, you just have to go pop your hood and look!
• If I'm retrofitting new style injectors, will I still need an adapter kit? : Selecting Late Style Injectors here will give you the right connectors, but you will still need the adapter kit for the injectors themselves. However, if you select Late Style injector connectors here, you can omit those from your injector adapter kit.
