So I ordered a 35w 4500K slim ballast kit from DDM and I can't get it to work.
1. Removed neg battery connection.
2. Removed original fog lamp (driverside).
3. replaced with HID.
4. connect circular connectors
5. connected male H8 to harness connection (sedan uses H8)
6. connected female plug to ballast
7. reconnected battery.

Start car, turn on lights, headlights work but no light from fog. Replaced with original lamp and it works fine. WTF? HELP PLEASE.

 

Do both not work? did you check the fuse for the fog light? i would just double check connections

 

Pics may help us diagnose. My guess is something is connected correctly.

 

its probably b/c the fog lights are 55W NOT 35W

 

That doesn't matter.

 

Here's a pic of my wiring. Not very good though.

 

Better one from the passenger side.

 

everything looks correct, i assume you plugged in the original connector from the car for the fog light into the HID kit right?

 

Got them working. Reversed polarity! See:

Sweet! Good to know. Post pics when you get them all installed.

 

Had to do that as well for my ddm motorcycle kit too...

and the 2010 stock fogs are 35w not 55w as someone said above.

 

DC voltage is funny that way

 

Isn't the OEM fog for 09's 55W? I figured they would just keep the 2010's the same

I was going off post # 2 and 4 from this thread

Lol! I threw a code in the process. No idea what it is. Does 2010 have an OBD II port somewhere so I can scan it? Will post some pics later.

 

According to my 2010 owners manual the sedan is 35W and the coupe is 55W.
