just had a look on wiring diagram for you... (series 2 turbo)
the brown and green wire goes to pin 6 (numbered 6) on the ecu which is the 3rd one from the end but check for the number 6 on ecu,check the contenuety on that from the plug,also the black wire (earth) from wot i can make out goes to the fuse box then to pin 15 on your fuel pump relay.

hope this helps.
