trim gauge problem
 

I changed harnesses on my engine and my trim gauge wires don't match up now. I have a tan/blue wire, a brown/white wire and a gray wire. My black sender wires have a male and a female. Which wires do I hook up to what.
I grounded the brown/white and the gauge pegs down. i've tried all combos and can't get the dand thing to work. It worked on my old harness.
I also have a black and a grey a little farther up the harness with female plugs.

the brown/wht has a ring terminal on it. The other two have female plugs. Thanks
