Okay, that's helped. I was looking at the one that connects to the ECU. Looks like i have to take the sensor/sender that has that has only 1 wire (yellow with green trace) off it. Thanks toyo.
It's funny though, i'm looking at the different wiring diagrams, one in the 'fuel management systems' and another under 'electrical system' and they show different coloured wires for the same connection type. It's right(connected to the same things in both wiring diagrams), but just another colour. e.g. water temp sensor is connected to 2 wires on the elect sys heading one 'green' and one 'brown', while on the fuel man system, one is 'black with red trace' and 'green'.
