pacolet Posted July 12, 2019 Share Posted July 12, 2019 Need to know what pin on the LS400 climate control unit provides ground for high speed blower speed. I've heard that it's #20 and that it's green/orange in color, but I don't see that exact color and I don't know where #20 would be. Specific help appreciated. The plugs look like this and it would be the larger one on the left: Quote Link to comment Share on other sites More sharing options...
