When swapping a 2JZGTE engine into a non Turbo chassis, you can now keep your stock GE harness by using these mini looms to adapt different sensors on each engine.
 
This harness simply extends the GE harness ECU & cluster Temperature sensors located bottom front intake side of the head and runs them accross the top of the GTE engine (just behind the Cam gears, under the engine cover), and plugs them in to the factory GTE sensors located on the water pump.
 
When combined with the Supravworld Coil on plug kit and Cam/Crank trigger Harness, this will run a 2JZGTE engine on the factory GTE ECU and allows you to use any aftermarket Plug n Play ECU with the start up/Base maps provided for the 2JZGTE engine. 
This saves you time and money from trying to fit a whole new harness when you already have one.
