Unless someone familiar with Audi says you need to use a aux resister harness, I would try it without and see first. If you notice the lights seem to flicker, then add the harness. **Q: Will this fit a 9006 connector? Thx!** A: Actually yes. A 9005 connector will fit in a 9006. But a 9006 will not fit in a 9005. **Q: Requiero el mismo conector para un Audi A4 2012 pero debe ser más largo ¿lo tienen?** A: no we do not have a longer version. **Q: I need a longer harness 24” if possible** A: no we do not have it in 24in. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great for my Acura Integra JDM headlights *by C***Z on June 4, 2026* These harness worked great for my jdm Integra headlights!
