I just got my HID kits for my heads and fogs. The only problem is that the H10 fog ki does not identify the hot and neutral conductors. The wired are blue and black. I am lacking a test light so I can not figure it out. I do have a multi meter. Any straight answers? I think the " hot" is the blue and the "neutral" in the black.

 

I believe you are correct.

 

Also. the kit is from DDM

 

That was wrong for anyone who cares actually, Hot to black and white to blue, but I can not get my passengers side fog light to work. I hooked it up exactly the same as the drivers side..? Do I need to reverse polarity on the passengers side?

 

they should be plug and play.....are you talking about the bulbs them selves or the ballast that plugs into your fog light plug?

 

I'm talking about the factory harness hooking onto the DDM harness. So the DDM ballast gets power from the factory harness. In order to go that you have to cut off the factory pig tail for the stock fog light and the push on connectors on the DDM kit and do a splice with heat shrink. I tried a few different things last night but I will change ballast today and bulbs if need be. I just don't get why it doesn't work. It should be connected the same as the drivers side? I think anyway.

 

Yes it should be exactly the same as the driver side

 

Finally they work.
