Frequently Asked Questions
Q: Will this wiring harness fit my 300ZX Z32?
A: Yes, this harness is designed to fit all LHD Z32 models, with the exception of the USDM ’96 (OBDII) version. Due to its broad compatibility, some models may have unused connectors, but this is normal.
Q: I am performing an AT to MT swap, which harness should I choose?
A: For the EFI harness, the transmission type is irrelevant. Select based on your engine configuration. The transmission-specific wiring (starter inhibitor, reverse lights) is part of the separate Alternator/Transmission harness.
Q: How do I determine my CAS/injector style?
A: While factory specifications can indicate the original configuration, these cars are decades old and may have been modified. The best way is to visually inspect your CAS and injectors under the hood to identify the style before ordering.
Q: If I am upgrading to new style injectors, do I still need an adapter kit?
A: Selecting “Late Style Injectors” here provides the correct connectors on the harness. However, you will still require an adapter kit for the injectors themselves to physically fit, available separately. Choosing late-style injector connectors on the harness allows you to exclude those connectors from the separate injector adapter kit.
Upgrading your 300ZX’s wiring harness with a Wiring Specialties VG30 harness is a proactive step towards ensuring long-term reliability and potentially enhancing performance, especially if you are undertaking modifications such as a 300zx obd2 motor conversion. This upgrade provides peace of mind and a solid foundation for your engine’s electrical system.
