Hello, New to this, I hope I posted in the correct area. I have a 2008 350z touring I would like to test the connector to the fuel pump I believe there are 5 wires on this pigtail but I do not now what colored wires does what. Can someone please point me in the correct direction I have looked but can not find the colored codes for this pigtail. Thank u...I looked on the service Manuel but still cant find the color codes for this pigtail and how to test each one and what my voltage should be at each point. I believe there is a cut in a wire someplace so I am trying to track it down. Rats!! This is the pigtail off the fuel pump. Any and all help is greatly appreciated

Thank u, but I am still having trouble I found the pigtail on there but no breakdown of the wires as to the colors and what they each do and how to test.
The two biggest / fattest / smallest numerical gauge will be your 12v fuel pump power and fuel pump ground. Your power is likely the fattest wire (likely your black/yellow) very common for nissan to use a thicker black / yellow wire for powering higher amp draws and usually grounds are solid black.
the remain three wires are a 0-5v level sensor and a temp sensor and a combined ground for those two. Don’t worry about these.
if I remember correctly the power will be on the far right and the ground will be in the middle of the 5 pin harness connector when you look at it from the front side of the connector.
This is from my 2003 DE setup but other than wire colors the general layout should be the same.
