Still looking for the Diagram in the mean time this may help.
The V6 were designed with two red and two black cables, with number idents on them, 1 (red) and 2 (black) to the Battery, 3 (red) and 4 (black) being to the pump. You can also tell the connections apart as the two power cables had male crimps, pump cables both had female crimps,
Heres hoping the cables still have the number tags on them
