A pin-out diagram for the entire ECU would be nice, or at least + - K-Line etc.

thanks guys so red-grey (socket3-location10) is 0-5v output and pink-black 5v input (which also powers the oil sensors) and brown-grey -ve ground?

Just to clarify!

Thx again guys!

On most Euro cars Brown color is the Earth / Ground. I tried to post a color schematic. The colors fade when enlarged

Do you have a voltage meter Steve? Be good to confirm it with that.

true but how are you going to produce boost so the sensor sends a signal. unless you have a boost leak checker but that will confuse to ecu if it see boost at idle or when the ignition is in position 2

yeap got a meter but trying to hook it up is not easy esp when trying to get a boost reading!!.. at mom I am tapping off the red-grey and see how it goes... its for my water injection think I may go boost based flow instead of IDC based flow.
