2007 yukon speed sensing wire

thanks, took care of this a little while ago. found out if you have a bose system, the speed sense wire should be on the radio harness. 

VSS Wire -- Location: ECM (located in engine compartment, drivers side, near radiator) Black 72 pin plug, the pin number is 57, the pin location may or may not have a Yellow w/ Black wire in it. If it doesn't, insert a wire /w pin.

 all Bose systems with automatic volume control (in the C6 GM calls it "Bose Audio Pilot") has the VSS wire going to the back of the radio, dark green with a white stripe. On the C6 w/Bose there are two dark green wires with white stripe on the 12 pin harness. One is at pin H and the other at pin D. The VSS wire is at pin D.
