This is for all JDM cars using the stock GE engine harness with a Forward facing intake manifold. 
This kit contains three mini harnesses:
 
1. IAT, (indicated air temperature). This harness needs to be spliced to the two wire running to your old maifold temp plug located just behind your AIR FILTER BOX. 
To install this, simply cut the connector off your stock harness, strip the two wire ends, and splice to the new harness in any order. The wire position does not matter for this loom.
Then run this loom accross the front of your engine, just behind the Cam gears and plug into the new AIR TEMPERATURE SENSOR located on you intake plenum. 
 
2. TPS (thottle position sensor). This harness swaps the wires around to suit the GTE stock positions in order to run either a stock GTE ffim or any aftermarket Forward facing intake manifold.
This loom simply plugs into you factory GE harness and then plugs into your TPS.
 
3. IACV (Idle air control valve) This is an extention that plugs into your factory GE harness and extends it to the intake side of the engine to plug into either the factory GTE intake plenum or any aftermarket ffim.
 
These harnesses can also be used to run 2JZGTE swapped cars using your factory GE harness. This must be in combination with a coil on plug kit and the CAM/CRANK sensor harness for GTE swaps.
