steve310 Posted August 24, 2007 Report Share Posted August 24, 2007 Speed Sense is the dk.green/white wire at the ECM. The ECM (Engine Control Module) is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the VSS wire is at pin 3 in the connector labeled black. On the 4.8L, 5.3L, and 6.0L, the VSS wire is located in pin 50 of the red connector. Quote Link to post Share on other sites
