ITS transom assembly wire help
 

Looking for some help identifying some wire coming from my ITS transom. I believe that the two ring terminals go to my mercathod but need help with the 3pin red, white and blue plug.. assume trim and trim limit with power? Now I am running a stand alone engine management system so just need to know which wire is for what.

That plugs into the engine harness for trim sending unit to display on smartcraft. There is not trim limit switch.

Do you happen to know the pin out? I assume one is 5v, sensor ground and signal?
