G4 Plug and Play XS Loom wiring diagram?

Recommended Posts

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

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.

Regards

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

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.

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

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...

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.
