I have a 1960 Austin Healey Sprite MK1, I’m nearing the end of my full restoration. I’m at the point dealing with the wiring harnesses, all was good until I got to the Red / Red-White Wire. Studying the wiring schematic it seems the red-white wires attache to the back of the Speedo, tach and the fuel gage, but it also shows the black wire their also. So this is where I’m confused, if someone has a clear answer to this situation with the Red wires your help would be appreciated.
