I read a couple of threads on how to do fog HID conversion and decided to do it for my 08 G37 coupe. It is a major PITA to do this so I really respect all the people who have finished this. It is almost finished but now I have a problem, the fog won't turn on. While I was doing it, I tested and everything worked like a charm. Even after putting the bulb in place, I tested a second time and everything was still working. Now after I zip-tied the ballast and the wire in place, the fog will not turn on and I have no idea what I did wrong.

Please suggest me as to where I should start to diagnosis the problem. Do you think I blow any fuse? Is the fog fuse in the IPDM box?

Now I did not know that the fog wattage is 55W so I purchased the 35W kit from DDM Tuning. Could that be the problem? Does anyone know if I can use the 35W ballast or it has to be 55W ballast?

Please help me out guys. Thank you so much

 

Almost all hid kits are 35w. You may have pulled a connection when you zip tied the wires down or may have blown a fuse. Check the owners manual for the fuse location and check the fuse. If both fogs are not coming on, that's most likely what happened.

 

Thanks for your quick reply speedracer, yeh, i found the fuse and i think i blew it. is there extra fuse inside the car or do i have to buy it at an auto part shop? i remember reading somewhere in the manual that there is extra fuse in the car. anyone knows?

 

Nvm, im gonna answer my own question in case other people do not know. There is a fuse puller and 3 extra fuse, 10,15,20amp in the kick box on driver side left foot (next to the dead pedal)

 

where did you find the fuse?? I was not able to find it on my 2010

 

fuse puller is in top right corner. spare fuses are at bottom left corner labelled SPARE

 

The coupes are all 55W and the sedans are 35W. You can use a 35W instead of 55W but not 55W instead of 35W.

 

does this one has it's own relay wirings?
