Wiring

Can someone tell me which wire going to the instrumant cluster is for the fuel sending unit? 2001 Silverado 2500HD 6.0L

It is a gray wire. Terminal A5. Sandwiched between a black and a brown wire. But, the gray wire is not simply a voltage input. It a data communication wire from the ecm

So are you saying I should'nt use it for my Intellitronix gauge signal? If not, which wire do I use? And thank you for the help,
