Service manual (not always sure I trust it for little details like wire colors) show the "hot" wire is RD/DG. I take that to mean Red/Dark Green.

You can download the service manual (use the SRT6 service manual, it applies to all cars) here on this site. Page 8W-10-22 shows the path for the fuel pump.

I'm gonna print out the picture MrMiata provided !
