An old speedometer cable makes a pretty good fish tape to try to run up through the windshield frame post. You can twist it a lot without getting any kinks. Be aware that you'll prpbably encounter some dead end passageways before the cable finds the right opening. Once it's all the way through, tape a wire on and pull it back through- - - - - -carefully!
