Hello all. I'm getting on with another little project at the moment and am using the guts of a 74/996 tacho in the build. I know the main wiring is: Blue +ve Black -ve Green/White Signal But the three pin socket on the back of the tacho obviously isn't marked up at all and I don't have a wiring loom with a plug on it. Could somebody have a look and let me know what pin is which wire on the connector. Thanks Nasher.
