Midlife 814 Report post Posted February 15, 2018 blue/red is for PRNDL lamp. blue with white bullet is for carb idle solenoid green wire is for your AC clutch. There are times when the blue wire is a grayish color, and sometimes green is a greenish blue color. Quote Share this post Link to post Share on other sites
