I had bought my boat used and the guy before me had Honda digital gauges installed. The gauges work great except they had disconnected all the analog gauges and my old analog fuel gauge doesnt work and neither does the one on the digital gauge bc they forgot to hook it up. What wires in the Honda harness coming from the gauge do I need to connect the wires coming from the boats fuel tank to? I already know what I have on the boat fuel tank wiring but have no idea what wires in the Honda gauge harness are the fuel tank wires? Anyone know?
