Thanks for taking the time to look over that for me Andy
The 18xe fuel relay and 20xe one have the same wiring colours and pin numbers with the exception of:
Pin1 18xe is brown/blue 20xe is brown/white
Pin 9 18xe is brown/green 20xe is brown/blue
The only haynes drawing I could see that had those colours for a 20xe fuel relay was motronic m2.8.?
Thanks again will wire as you and Phil said.
