TACHOMETER|white *5 | |ECM *3

*3 ECM is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the tach wire is at pin 20 in the connector labeled red, and VSS wire is at pin 3 in the connector labeled black. On the 4.8L, 5.3L, and 6.0L, the tach wire is located at pin 10 in the red connector, and VSS wire is located in pin 50 of the red connector.
