Front end damage on my zenki S14 led me to convert to a kouki s14 front end. I did not know the wiring would be different between headlights (low beam) and my wiring skills are not the cleanest. Luckily I found Key'd Performance and ordered this adapter set, it made everything truly plug and play while also adding a relay! Not only does the product look great, but its also done the right way. No doubts about the quality of these products, the only downside is on my wallet because I keep finding things on this website to purchase! Haha, will definitely be a returning/frequent customer.
