well, I've mounting my cylinder head again and I've a doubt with the black temp sender assy ... It has 2 wires connected or only one ? I've 2 wires (brown-green & brown-black) lost here and I haven't other place to wire in ! The blue sender is well connected ( I think )

 

Brown and Green should be the oil pressure switch IIRC, and Brown and Black the Water Temp sender (not the Ecu sender).

Hope that helps.
