The passenger side headlight is causing me big problems. First of all, the high beam did not function while the low beam did. I removed the headlight and retainer ring. However, the red wire broke away from the plastic headlight connector. How can I remove the metal insert from this plastic connector, and reattatch the red wire to the metal connector nad insert it back into the plastic connector. OR, do I have to buy a whole new headlight wiring assy? Please help.
