This is for the GT1R secondary injector addition harness.
There are 3 pieces to this loom.
Piece 1 will attach to the ecu, with a nearby connector allowing easy ecu removal.
Piece 2 attaches to the injectors and has a nearby connector, allowing easy intake manifold removal by simply disconnecting the single connector.
Piece 3 goes in between these two connectors, as an extension loom from ecu to injector sub-loom.
There are two versions of the harness which only differ in wiring color due to supply issues. Please download both files below and verify which version you have before installation to avoid complications.
