so i got my H4 kit but ive been all over online and and the kits are different from what i got and i notice, to power the ballast you connect the Power wire to the battery and theres a ground with some relays aswell. i just hooked up the same Exact(h4) kit to my 95 civic and the power pulls in from the 3 prong plug.. with no ground shat so ever.. whats am i doing wrong for the 06 si? is there no prong plug?

 

Civics from 06-09 have a 9006 bulb, not H4.

 

mmm how come on the headlight is says hb4? :/ dang this sucks.

 

HB4 = 9006

H4 is a whole different socket.

 

That clears things up.
