Need help with send and pump wire on EFI tank

[qnitro]

Hows it going guys.. I need help.. I know this is a basic question, I bought a spectra tank, same as b-man(stole his pic), Im building a 66 Lemans with a LS1... anyways, I know the 2 wires are grounds, than there is a purple and a gray wire... which is the fuel pump power wire?? I bought a speratech harness with the fuel pump relay.. Thanks for the help all..

I just put one in this weekend (GM32AFI) The black wire is the ground. The grey wire is power to the pump and the purple wire is for the fuel gauge sending unit.
