Anyone know the VSS & Reverse colors and location?

 

Thanks!

Speed Sense dk. green/white ECM

 

ECM 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.
