I’m not a mechanic by trade but I’ve been busting my knuckles on vehicles since high school (40+ years) and I am seldom without a manual for the vehicle at my side. A Chilton, Motor or Haynes repair manual will walk you through most anything you would want to do. Haynes are available at book stores or auto supply stores (and on Amazon too) for about $15, and all are available at the public library. Any of those would have allowed you to finish the job without washing up and punching computer keys.
