I have a '93 TT and am having the injectors replaced. I purchased the injector kit from Courtesy which includes two new harnesses (part #24079 ) with plugs for three injectors each. The new harnesses only have two wires coming out of them and this has me confused. How do you control three injectors with two wires. I checked the wiring diagram and each injector has it's own wire. Has Nissan changed something or am I missing something. How should the new harness be connected to the existing one? I called Courtesy and they weren't much help.
