ok, i thought it was a different style, but what is the difference between stock and the h4 and any benefits to this harness?? any problems??

 

you are looking at cefiros, correct?? if so we use 9004 and the cefiro uses H4, therefore a harness is included to make your 9004 into a H4. you know how the r34 has 2 bulbs well they include a harness that makes the 9004 into a 9005 and 9006(its plug and play). with the cefiros though i think some splicing is required, i dont think they are plug and play. someone with more knowledge of them can help more. I have never installed cefiros

 

yea, they're not plug and play. I tried making a plug and play...i failed miserably. Ruined a perfecty good bulb...::sigh::...so i just used wire taps..-= 0
