Brake Pressure Sensor

[fatjon]

I have an application which needs to monitor brake pressure so I found a couple of brake pressure sensors (Audi A2). Anyone know what pin is what on them. I assume it's 5v, GND and output but can't find any documentation about which is which.

Sorry, I know it's not really engine technical, but it is technical!

thanks chaps. I reckon volt drop over a 470R should be minimal at a couple of mA so will try that to be sure I dont fry it.
