Fox06LegacyGT Posted November 17, 2008 Share Posted November 17, 2008 speed sense is Green/Black at ABS control module or instrument cluster tach is Pink to Red/White at ECM(behind glove box, 34 pin plug, pin 23) or at the cluster It is much easier to get tach at the cluster and I assume speed sense as well. Tach is Red/White behind the cluster. Please test to make sure you are tapping the right wires, you would hate to blow something up. Link to comment Share on other sites More sharing options...
