DIY: 350z 06 headlight upgrade walkthrough
How about you clarify your question and give some background information first before you throw your fit?
Start by telling us what you're trying to do. What I gathered from your previous posts (I had to piece things together...) is that you're putting 06+ headlights in your '04.
Now the things that make a difference is whether or not your vehicle is a base model. This is because the base model came with halogens and the harness is different (6 pin). The 06+ headlights are 8 pin and will bolt-on to anything that was factory equipped with HIDs. Just slap on the correct bulbs, cover and ballasts and you're all set (if you only got the housings). I recommend getting them as an assembly so you don't fry anything by mixing and matching new/old parts or incompatible parts.
However, if your car IS a base model it becomes more complicated. You will need to either cut the harness on your car to convert to 8 pin or cut the harness on your headlights to convert to 6 pin. You can find the connectors from dead Zs in the junkyard, on old/broken headlights or from other cars that share the same harness (I know Nissan Muranos use the same connectors). Do some searching on this forum for the wiring then cut and solder away.
Okay first of all not getting cranky or throwing a fit, but a least it got a response.
Now to your answer, mine is an enthusiast not a base (about 15 posts ago in this thread). I think I got changing the bulbs and using my old ballasts in the new style housings. My question I thought was simple and to the point. My car has a separate high beam and low beam. There are two separate bulbs and wiring harnesses there, one HID (low beam) and one H7 (high beam).
So that being said, how then will the lights change from low to high beam when I move the turn signal stalk forward and then back after just plugging in the low beam harness (HID with ballast) to the new bulb and installing it?

You're using the old style bulbs that came on the old HIDs which were not "bi-xenon". The whole point of bi-xenons is to have a high beam and low beam that are on the same bulb. What the old HIDs had was two bulbs, a HID low beam and a regular halogen high beam (easily distinguishable by the color of the light).
Keep asking questions when you got them and don't get impatient, somebody will answer you sooner or later.
Thanks Raybrant for your help. So the switch will make the ballast control the bi-xenon and switch from high to low? I wasn't sure if I had to do something to the wiring or switch itself. I figured the high beam harness would not be used and would be just tucked out of the way.
I have not bought anything yet, just trying to get the facts straight and figure out what I need before I buy anything.

If you haven't bought anything yet, just buy a set of 06+ headlight assemblies so that they come with everything hooked up for you to just drop in. From what you're telling me, you should not need to do any wiring, cutting or soldering.
Buy 06+ headlights and sell your 03-05 HIDs (they don't sell for much... ask me how I found out).
So basically if I buy a complete set it is plug and play and no need to worry about how it works, it just will. Cool.....now to search for headlight 
Thanks for your help.

Thanks for your help.
when i installed 06 headlights on my 04 i literally just plugged in the one connector and everything worked perfect, no modifications were done/needed besides snipping a particular wire so that the drls were not on... i dont understand the point of this thread. please inform me
I Think..... What's happening here is that there are 2 different type styles for the '06 oem headlights being talked about with HID set-up for '03-'05 models.
1. The oem '06 headlight set (complete) from Nissan dealer requires just plug in with little modification. Appox. $1100.
2. The other oem '06 headlight set that sells for less money (Appox $650) on ebay & elsewhere needs to use the harness from your '03-'05 headlights and new bulb is also required.....this set is what OP is using in his diy. I Think!

Some people in here are confused about how the high beams work in the 06+ lamps. Most likely they are like other "bi-xenon" setups and has a servo / flapper mechanism that adjusts the angle of the light when you flick the ****. It uses one bulb.

Potato: Any issues with the '06 turn signal bulb or LED parking lights? Notice a member stating his amber turn bulb stays on constantly and the LED lighting not at all. A member stated he had to adjust some wiring. Thanks!
My blinker stays on, although its not as dramatic as some make it out to be. The constant running light isnt as bright as the blinker itself. Im either going to snip a wire or cut/tape off the contacts of the blinker bulb.
