[DeTomaso] gas tank sending unit question

[Christopher Kimball]

I'm putting my car back together and when disassembling things, apparently, 
didn't bother to mark the three wires which attach to the sending unit on 
top of the gas tank.

One is a ground, the other two plug into the male tabs in the center of the 
sending unit.

Does anyone out there know which color wires go onto which of the two tabs 
and the ground tab?

I appreciate the help.

Thanks,

Chris
