Can anyone help me regarding installing a trim gauge. I bought a new boat but no trim gauge so I`m trying to install one.
It is a 2019 Yamaha 4 stroke 175.hp.
I look under my dash for what I`m told should be a pink wire? I did find one but when I hook it to the S- terminal and run trim up and down I get nothing?

Thank you if there is anyone who can help.
Steve
