1JZ-GTE and 2JZ-GTE Engine Wiring Harnesses - Tweak'd Performance

Brand New 2JZ / 1JZ Engine Wiring Harnesses These wiring harnesses are built using new wire, new OEM terminals, and new OEM connector housings. Available for auto or manual transmission (auto is $200 extra), and can be set up for universal use or made completely plug and play to your specific chassis. Your original engine harness might be required to get the body plugs from, but everything else on this harness is BRAND NEW. Are you running a stock ECU? AEM? ECUMaster? Haltech? ProEFI? Infinity? GM coils? ID2000, ID1000, Bosch, Denso injectors, flex fuel, no problem. We carry in stock every connector for every single EMS, injector, and coil option so when you order a harness from us we can have it put together and sent your way as quickly as the next day for extremely urgent jobs! Equally important as speed and customizability is the fact that all of our harnesses are made here in the USA, while many companies send their production to be done in totalitarian countries with unethical labor practices.
