Lol, i've asked Rupert to update his instructions to include this info (i emailed him to ask to be sure).

Red wire - 12v supply (switched) inside car
Brown wire - signal from knock sensor (red wire)
Black wire #1 - earth from knock sensor
Black wire #2 - earth inside car

EDIT: have just realised you want to wire into the OEM sensor. The above should still stand true but i'd use the sensor supplied.

cheers mate,didnt get supplied sensor,guna use oem one.

I would get the ecu pinout diagram and then take the knock signal from there (ie splice into the signal wire and run this to the brown wire from the display). If you use a significant length of wire then it may need to be shielded.

If you do this then you should not need to connect the ground sensor wire from the display at all.

As far as I am aware you are the first to try the oem sensor - letme know how it goes.
