I have a 2018 Merc. 1504S,it has a 3wire trim sensor that I think is a digital sender. Is there a analog sender that I can get to replace the present sender so I can use a standard trim gauge? I don't want to put in a MercMonitor in! What would the two wires (brown/white strip & black) be hooked to. There is a brown/white wire stub laying below the 3 wire hookup,plus 2 other wire stubs.
