Ok so im going to put cefiros in my 98 I30, but i need some instructions on how to change the 9004's to H4, (or are they h3's) also what do i need to do to the side lights

The more detailed the better

Thanks a bunch

 

i think with the 9004 to H4 wiring, you just swap the ground and low wire, i have the cefiros also and i used the original corner bulb socket and cut away some of the tabs on the cefiro corners and made it fit, thats what most people with cefiros do

BTW, what cefiros did you get and where?

 

Did u buy a H4 harness tho? Like, I am installing mine this weekend (in the middle of the job) And I did not want to solder the wires to the back of the H4 bulb... For now I just jammed My H3's into the Cefiro housing for now...

 

H3's? you jammed your fog lights into the cefiro housing?

 

Sorry, I might not know my terms here. I put my old 9004 PIAA Xtreme white plus bulbs into the new cefiro.. using them for my main headlights for now.... Do I need to buy a harnest to connect the bulb type that comes with the cefiros?

 

yes, you will need an H4 harness to convert your existing 9004 to H4

 

Where can i get one?

 

Ebay has some. Don't know how good they are though.

 

I got the Nokya H4 Wiring Harness from ebay for 14 shipped, its working fine for me so far, its been about a 1.5 months now
