im swapping a C4 URS4 with a 2.7T from a 2004 A6. the ECU obviously mounted on the drivers side in the rain tray, well now the ECU is where it originally was in the C4 in the false floor on the passenger side so my harness essentially flipped so what was my drivers side injector connectors now land on the passenger side bank of the engine. this made me start wondering if i could just rotate around the firing order of the injectors and coils in the ECU instead of cutting apart, lengthening and shortening a pile for wire for all those devices on the engine.
