Does anybody know how to remove/install a 91egt(manual tranny) speed sensor. I went to autozone and they had three different colors; Green, White, and Yellow. I took a wild guess and bought the Green one. While install my new gauges, I must have pulled on the speedo cable too hard and accidently screwed up my speedo. I'm not sure what color senser i need and I'm not sure exactly how to install it. Does anybody know which one I need and how do I go about putting it in?
