If you're in an NBS, you only need the switched power from either the left or right OEM plug. I know, it seems weird, but you'll only use the driver's side plug for the relay.

So i just leave the other side of that relay unplugged? or can i run that one down to my fogs so I only use 1 relay kit for both my lows and fogs? Not sure if the fuse can handle both or not.

I dont have a problem with it, i just wanted to double check before i went and did it. I figure I had time since they sent me one wrong HID relay kit, and one right one. I will say DDMtuning e-mailed me right back and is already working with me to ensure the problem is resolved.

oh, and why would they have the relay kit come with one shorter one to attatch to the drivers side, and a longer one to reach the passanger side if u only need one? i cant see it hurting to run both, since its in parallel

the relay has 2 male 900x connectors and only 1 female 900x connector.

You only plug in 1 factory 900x headlamp connector, drivers/pass does not matter. That's all that's required to "trigger" the relay. Once triggered, it draws power from the direct ground and (+) battery, firing up both ballasts via the 2 male 900x connectors you've attached to the ballast itself, or short extension wire.

Both are not required, as only a small amount of voltage is required to trigger the relay.

The free/unattached male 900x factory connector, I suggest you glob some electrolytic grease on it and tape it up out of the way so it does not get corroded.

i would assume that if one balast (drivers side) has the sufficient voltage, the maybe the pass side wont? simply because the gauge of wire going from the pass to drivers side is so small. not sure tho. but im going to try it out.

ok the male end connects to the headlight harness in the truck, and the female end connects to the ballast.

lol yeah i know that. the question is do i need each set of connections goin to each balast, or if i could use just one relay kit and have each set of connectors going to the drivers side bulbs (low and fog drivers side balasts) then just the pass side connecting to their balasts and to the factory harness

ah ok you need to connect one to each ballast, thats how they are getting power from the battery thru the relay.

but instead of plugging the passanger side into the relay kit, i could plug it into the factory harness, which is tied into the drivers side, which is connected to the relay kit. so i think that should work. eh?

just for anyone who orderes from DDM tuning...the HIDs dont work without the relay kit, and they both have to be plugged in to work. low beams are in, awaiting the correct HID relay kit to do the fogs.
