SSGmonroe Posted July 12, 2022 Report Share Posted July 12, 2022 I have a 2004 Pontiac Grand Prix GT. I have an NEX 8500 in it. Recently the speed pulse warning appeared on the screen. Which wire do I need to look at to check to make sure it is still connected? Quote Link to post Share on other sites
