I had to extend the O2 plug to reach the sensor. So instead of extending the plug from the O2 i extended it from the engine harness. I noticed that one of the 4 wires where allready cut and it was the grey wire (thickest one) insulated/shielded? and the wire inside of it is white. Does anyone knoe why the grey wire is like this? is it just for insulation or is it acutally ground for this wire?
