I took my 2007 (NEW BODY) Silverado back to the installer to hook up the VSS wire but now the speed pulse reads in 7 digit numbers in the #D calibration page????? no idea what that means. Also when I change to the connections page I get an error that the speed pulse wire is not properly connected please check connection and reboot system. Any idea what might be causing this? Did the installer hook up the wrong wire?

 

thanks
