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.
It is on the bottom connector of the ecm. It is there I assure you, there are alot of grn/whites there though.

thank you for the information i connected it to the ECM between the battery and the fan down low on the red plug  pin # 50 in the GREEN/ whtie wire and it still didn't work i drove it to see if it will read it but didn't do anything the screen it still shows ''item not abailble now'' might guess is that the unit doesn't work or if someone with this unit (pioneer avec-d1) have it, please help me out.thanks

I have an '01 Suburban and am having the same problem.  My ECM doesnt have a red connector.  There are SOOO many GREEN / WHITE wires - yikes.

Thanks, Shawn

2001 or 2002 (2002 and earlier) Suburbans (Tahoe, Silverado, C/K PU etc) have Cruise control
The plug at the Servo (near the brake booster) has the GREEN / WHITE VSS wire
