Tom Posted September 19, 2013 Report Share Posted September 19, 2013 I have a custom harness for my 4 cylinder motor made for the G4, prepared by my dealer.  In it, each of the four injectors has its own injector pin, even though I don't have a cam position sensor and will not be running sequential injection. As a test set-up, I've been working to build a jumper harness so I can plug the g4 box directly into my factory harness, so that I don't have to replace it with the custom G4 harness just yet.  The factory harness has virtually all the wires as the custom G4 harness.  However, in the factory harness, I only have 2 injector wires, and each is connected to 2 of the injectors.  Is there a way to use this wiring with the G4?  Can I connect the two factory injector wires to inj1 and inj2, only,  and run in batch mode? Quote Link to comment Share on other sites More sharing options...
Simon Posted September 19, 2013 Report Share Posted September 19, 2013 Yes just connect to Inj 1 and 2 drives and select multi point group injection mode. Make sure the injectors are high impedance or have had ballast resistors fitted. Quote Link to comment Share on other sites More sharing options...
