I had a Suzuki DT 100 motor on my old boat with a gauge that plugs into the harness and it worked fine. I took that motor off and put it on my new boat now the gaulge isnt working. I tested the wires going into the gauge and none have power. this is the older gauge with oil level on top,temp and rev on the left side. Does any one know if i have to power it up some how ? And if so what wire am i looking for ?Thanks Mike
