GBMUD Posted June 5, 2015 Share Posted June 5, 2015 2005Td5 D90. Earlier I was fitting cruise control with a SpeedoHealer as described by V8Freak here. In order to fit the cruise I have added some connectors in the ECU black plug, and to make the SpeedoHealer work I have interrupted pin 13 where it enters the ECU and connected the SpeedoHealer in series - as per the directions. Now my speedo does not work (and nor does CC). As I understand it, the speedo is fed from the speed transducer (which also gets a live and earth connection) in the back of the transfer box and the speedo then sends a signal, via pin 13, to the ECU. So I should not have upset anything, right? Well, something is obviously wrong. Do the wires to the speedo pass through the driver side seat box and could I therefor have upset them? Have I fried the speedo working on it live? ..I know, I know. Is there a fuse I should be checking? Any help much appreciated. Chris Quote Link to comment Share on other sites More sharing options...
