This has turned out to be a bit confusing. The VR diagram in my post #2 shows one connector to the body of the sender unit which which contains the (C) level sender earth and the (D) level sender signal. The other loose connector shows white and red wires but both are labelled as fuel pump on. Presumably the red wire is the (A) fuel pump power wire. Don't know about the white wire.
Searching around, I found the information and VS diagram below, as well as the link for a new connector that you could plug the VR wires into to attach them to the VS sender.
(A) thick purple is fuel pump power
(B) thick black is earth
(C) thin black is level sender earth
(D) thin yellow or tan is level sender signal
