Paul, The black wire is ground (earth) and is part of the front wire harness. This harness is grounded at the top front of the frame extension where the LH horn is attached.

For all who read my last post. I have had my dad move the wires to the sender and multiplug with me sitting inside and no different on the gauge. So I was wondering as my fuel gauge does start working again then not i.e if you go over a bump in the road,perhaps it's a bad earth? Does anyone know which wire of the 3 is the earth and where does it end up? If it leads to a bolt on the frame I could clean It up. Many Thanks. Paul.Vin 741.
