So I search back for this, but all I can find is "disconnect the trim guage" when switching to digital trim.
But what wire to disconnect? There is a multi-wire harness about 10" from the gauge (Tach/Trim combo), and the wires have ring terminals that get screwed onto posts on back of the gauge. But I just don't know which wire to disconnect? :)
There is a pink wire, so at first I assume that would be it, but figured I better make sure.
