NOT-MEE Posted June 21, 2008 Report Share Posted June 21, 2008 I have been searching other forums looking for where to hook it up. One post I found said the boise radio connector had it and where to hook it up.I did like instructed and no speed pulse is there. I have a full aftermarket system avic d1 amps and speakers. The only thing used on the oem stereo adapter is Ground and Constant 12v. I don't have a power antenna so no other connections were needed. Anyone have any experience with this. I have attached the picture from another forum with where they said to connect speed pulse. Any help will be appreciated Thanx Quote Link to post Share on other sites
Crackerzot Posted March 14, 2010 Report Share Posted March 14, 2010 For the benefit of future C5 owners looking for the answer, this is POSITIVELY NOT the VSS wire on a C5 Corvette. There is no VSS wire on the Bose harness connector, period. Any speed related volume control is handled by the data bus wiring in the harness. The VSS can be tapped in the instrument cluster harness behind the gauge pod and you have to pull the gauge cluster in order to get to it. PIA. I've opted to leave mine disconnected for now.

mikzgp Posted March 23, 2010 Report Share Posted March 23, 2010 The VSS wire can be pulled from other places. I would go down to the dealership and have them print out the PCM diagram for you. I did this for my car and it worked great. Quote Link to post Share on other sites
CaptainInsaneO Posted March 23, 2010 Report Share Posted March 23, 2010 This is an old thread but I'm going to post this here since it's relevant and may help someone in the future: The VSS wire is on the PCM, C2 connector which is red. It is the 21st pin, the wire is yellow. Reference this link for more info: http://corvetteforum.shelor.net/Corvett ... Pinout.htm Quote Link to post Share on other sites
