Wiring Harness 2.5 EFI

[WOT RACING]

I have a boat that was powered with a Etec and the gauges are basic universal Faria gauges. The RPM is a Fario Euro with warning lights and the gauges all have plugs in the back for simple hook up. When I derigged the Etec everything unplugged no cutting neccessary. What do i need to plug my merc harness right back in?? And what wires go to what? Does anyone have a good pic of a diagram?

Take a pic of the plug and post it up. its probably a deutsch DT or DTM style connector. Once that is determined, then you can call up an automotive supplier and order a plug kit for your harness. The merc you are going with will determine to what level that gauge will work. Should be pretty easy to find an instruction booklet on the web somewhere for the gauge.

Take a look at the photos and they should help with my issue.

After looking at the photo I wonder if these guages are just OMC only and not compatable with a merc

they look like omc system check style gauges to me.
