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.
