John Smith Posted July 12, 2013 Report Posted July 12, 2013 Hi There, ECU: Link G4 Plug and Play Vehicle: 1998 R34GTT with RB25DET NEO I have a link G4 plug and play. I'm looking to use the XS Loom to wire in my wideband and a few other sensors but i can't find a wiring diagram for it anywhere. There is no connector, hence no pinout. Does anybody have a link to a diagram so I can work out what wires do what? Any help appreciated.Thanks  Quote
simon gottlieb Posted July 13, 2013 Report Posted July 13, 2013 Have you purchased the xs connector? If so the diagram is in the startup instructions of the ecu Quote
John Smith Posted July 13, 2013 Author Report Posted July 13, 2013 No unfortunately not. It came with a vehicle that I purchased and now i'm using it in another car and require the use of the XS Loom.  I have PC Link with it's help guide, but i can't seem to find any information about it in there.

Simon Posted July 15, 2013 Report Posted July 15, 2013 The pinout is printed next to the connector on the ECU bottom board. You will need the correct connector / loom to attach to it. See attached image from help file Quote
John Smith Posted July 16, 2013 Author Report Posted July 16, 2013 So i need to pull the ECU out of it's housing and there is a pinout on the board? Doesn't Link just have a colour guide for what wires do what on the XS Loom?Thanks and Regards Chris  Quote
Simon Posted July 17, 2013 Report Posted July 17, 2013 It varies for each plugin application so the colour is not constant. And might also change without notice should we have a wire supply issue. Once I'm back at work ill check for colour to function on a board. Quote
Simon Posted July 17, 2013 Report Posted July 17, 2013 On your board the colours will be as follows. Green = Ground Red = 5 volts Grey = DI5 Brown = DI6 White = Volt 5 Blue = Volt 6 Yellow = Temp 2 Orange = Temp 3 Quote
Simon Posted July 22, 2013 Report Posted July 22, 2013 None of our G4 boards have a 2x4 connector can you post a photo? Quote
Martin Hanbury Posted July 24, 2013 Report Posted July 24, 2013 No problem mate, I've attached a couple of photos. This is the only secondary harness that I can see coming out of the ecu, and I purchased the XS loom at the same time and place as I bought the board (RPW in West Australia). Whether my tuner has chosen to install a completely different harness I couldn't tell you, though I can't fathom why they would do that when I supplied them with the correct one... Quote
Simon Posted July 25, 2013 Report Posted July 25, 2013 Sweet they have added their own plug to our loom. So in this case yes the colours will match assuming its a R34 Gtt ecu. Quote
