  1. Problem solved. I went out under the hood and tapped the green/white wire in the Cruise Control harness. The AVIC-N2 recognized the VSS instantly. This leads me to suspect that (1) there is a connection problem with the green/white wire in the Radio Harness, or (2) General Motors has run that segment through some filter for exclusive use with their factory radio. So, bottom line for 2001 Suburban is go to the Cruise Control harness and it's an easy splice. Best, Dan
  2. Thanks for your reply. I have two plugs in the harness for my stock radio - one is (9) pin and the other is (21) pin. The drk green/white wire which should be the VSS is located in the 9-pin harness. Does that agree with your data? Again, thank you in advance.
  3. 2001 Chev Suburban: OnStar and factory amp - No BOSE I've located the green wire in the radio harness and elsewhere at cruise, PCM, etc. Can anyone confirm what readings I should see on a meter when driving and measuring A/C voltage (to ground) from the VSS wire. In my case, at idle or 1-2 mph A/C voltage is approx 0.081 and at 60 mph A/C voltage reads approx 1.62. This is a linear increase/decrease that seems steady as speed increases or decreases. Problem is my AVIC N2 doesn't recognize it as VSS connected. Any help would be appreciated.
