9004 to h4h/JDM one piece

so i just bought this jdm one pieces today.came with all the bulbs even the corners and fog light but no harness… ive been doing some reading about them and the bulb sucks. Wish they were atleast 9004 to save me a headache.a anyways im planning on buying passwordJDMs 9004 to h4h plug. for now i will be using the h4h bulbs…i tried fitting my regular stock 9004 bulb to check difference and i compared it to a spare new HID kit that is H13…seems like the H13 is less work to dremmel to make it fit…curently im using a 9004 HID kit on my car… which im positive it wont fit…should i cut the H13 bulb to fit and make a female and male conncetpor from h13 to h4h…

as u see i have many ideas in mind and some are just dumb,lol…but i need some help here atleast to know that im wrong since this my first JDM one piece install…

conclusion; im guessing i should just get the 9004 to h4h harness from passwordJDM and then buying a New HID kit for jdm front lights h4h ! suck tho cus i get any hid kit for $30 and closest to h4h is h4.or or should i modify the plastic H4 HID bulb?.. im screwed i guess. any one know of a good H4H HID kit thats has been lasting a long time…??
