haha nice vid mate,
I do have quite a large wiring diagram (packed away) and my speedo does work, I'm sure its the green/yellow wire from memory,
I'm sure they are on forums etc, or even shoot Matt a msg??
I'm guessing my tacho don't work being the ECU having an electronic signal as opposed to analog, its annoying at times, so pull up resistor,
Also with the fuel sender, i have the standard KE unit in there, just above the quarter empty mark is when she is out of fuel, FYI
