Digidash transducer help

[dan-hipgrave]

Hi, i have recently put a digidash into my car, but it didnt come with the cable running from the transducer to the back of the dash, so i am going to run 3 wires myself, but i need to know which pins on the transducer are live, earth and signal before i can do this.
Cheers, Dan

brown is earth
black is 12v ignition live
red/blue is signal

what i mean is the actual pins on the transducer as i have no way of telling what they are meant to be cos they are not labelled or marked in any way..hope this makes sense
