supra_ufo Posted April 5, 2016 Share Posted April 5, 2016 (edited) Right folks I haven't made a thread specific to the issue I am having. Many moons ago I had a problem with my speedo not working. After diagnosis, which involved removing the Speed converter it turned out the issue was the COG that sits on the speed sensor that was at fault. During that time I somehow managed to break my rev counter in the process I had a lot of things going on around this time so I cant remember exactly what I did to break it. Recent work carried out are LED conversion on the dial cluster Installation of another speed convertor / delimiter The gear selection are working and lighting up correctly when I select the gear I have tried another speedo cluster which does not work either. So its looking like a wiring fault somewhere I have wiggled the wires whilst revving the car but I get nothing! Can anyone tell me which wire it is that controls the revs from the ECU and from the back of the connector so I can test those wires please? I have also tried Ikys speed sensor incase it linked with that but the Rev counter does not work. I have seen people use aftermarket Rev gauges so surely there is a way to tap into a wire... thanks.

Chris Wilson Posted April 15, 2016 Share Posted April 15, 2016 A garage with a scope and the wiring diagram could easily probe from the pink / silver wire at the ecu connector through to the tachometer to see where the signal is lost, or if it's a tacho fault. At least that's how I would do it Quote Link to comment Share on other sites More sharing options...
