The LOJ Conversions Swap Harness for the Infiniti G35 and Nissan 350Z is like nothing else on the market!!

The LOJ Conversions 350Z and G35 LSx Swap Engine Harness is a completely new harness, not a rewire service. These harnesses are made specifically for use with Gen 4 LSx engines with 58X crank reluctor wheels when swapped into Nissan 350Zs and Infiniti G35s. This harness completely replaces the factory EFI harness.

Harnesses include a patent pending, proprietary CANBUS translator to allow the GM ECM to speak to the Nissan/Infiniti Vehicle and vice/versa. What does this mean?

  • Your stock Nissan throttle pedal will operate the GM throttle body. There is NO NEED to swap pedals or to convert to drive by cable!
  • Your factory tachometer will function properly. There is NO NEED to install costly aftermarket gauges or hack up your interior!
  • Your factory coolant temp gauge will function properly.
  • Your factory check engine light will function properly.
  • Your factory HVAC Climate Controls will function as stock, including AIR CONDITIONING, when using the LOJ Accessory Drive Kit and the stock AC compressor. 
  • Your factory ABS will function properly.
  • Your factory OBD2 will read all vehicle and engine data, and can be used for tuning the GM ECU as well as emissions related testing and diagnostics functions.

Harnesses are professionally constructed from Brand New GM Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications. All harnesses are 100% Quality Inspected prior to shipping. Note that harnesses are for non-emissions equipped vehicles and do not include air pump or EGR provisions. All harnesses require ECU VATs removal, available through LOJ. Please contact LOJ for more information.

Harnesses are available ONLY for Gen 4 Drive by Wire (DBW) engines using E38 ECMs.

After Purchase, LOJ will contact you for details regarding your exact setup, so the harness can be spec'd to meet your needs. Details we will need to know include Injector Type, MAF Type, etc. 


I was reminded this morning, two years after I bought my Z32 swap kit what a great company this is. LOJ is always there with excellent advice, not just great products. Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it. Click Here to See Review
