Hi John,
Black goes to eh 19
grey goes to e4
white can be connected either way but 1 is switched 12v and the other goes to eh 10
This presumes you are using the engine harness plug??
wire 5 goes from anywhere on pho2s to e3 make sure none of the braid touches the connections on the the ecu as this will throw up an error code lambda low voltage!! I know as I had this originally
Now running sweet 0.10-0.15 v this was my last error code and my engine is running very sweet, I was lucky it seems as once lambda was sorted no issues engine idles at 1500 stone cold and 750 warm with no jumping or uneven idle
