Ok guys, rather miffed on this one and need to see if you can help. I bought these headlights (i think ACA) around 3 years or so ago and just now getting around to installing them. Long story, just got busy/lost motivation.....bleh.
Anyway, my question is concerning the harness. In the picture, you see everything i have for one side (headlight). Now, my question is, I don't have enough plugs in the harness to accommodate the two ballasts that came with it and obviously connect to the bulbs. What am i missing as far as how everything is cabled?

I think the wiring kit you show is only for the two HID bulbs, one HID for each side.
Each housing in the pic has a single HID Projector which is why there is only wiring for those two HIDs.
The socket on the left of the housing is for the original headlight bulb.

I am only showing one side I’m working on. Basically I have two sets of what is shown. Also note, the bulbs are in a set of 2, high and low. Basically everything you see here is doubled
Ok....so I think I am on to something, but maybe someone smarter than me can correct me if i am wrong.
To me, it seems that this kit was shipped with possibly 2 different scenarios:
1) Maybe i reuse the existing bulbs or bulbs with similar connectors as stock. You are replacing the housing and maybe have other bulb options with the same connector.
2) I opted for HID bulds for high and low and now have different connectors, which now require the ballast.
So, my thinking is, I don't need the long wire harness that goes to the battery terminal, but instead, have the ballasts go in between the stock harness connectors, then to the new bulbs? The ballast will regulate the current, but is the current good enough?
***edit***
So i marked up the picture for more thoughts.
The GREEN arrows will be where the connections from the stock harness. The WHITE arrows show that they are plugged into the bulbs with the long power harness going to the projector/low beam, with #1 going to high beam and #2 going to low beam/projector. In this case, the ballasts are not used.
I'm beginning to think that I may be right with how scenario #2 goes, with the ballasts being between the stock harness and the HID bulbs.
Testing theory here in a few to see before putting everything back together.

Reason: more input
Ok, so that didn't work, but the more that I thought about it and watched a video, I think I have found the pattern.
I'm convinced that the green arrows point to the connections that plug into the stock harness. They are keyed to those connections. The orange arrows plug into each other giving an extension plus changing the plug for the ballast (the prongs inside the plug match up wit this connector). Which leads to the blue arrows showing what i just mentioned for the connection to the ballast. That leaves the yellow arrows for the last connection, but really has me scratching my head as to why, what would be a power run, be plugged into only one bulb?
I was having some problems getting the ground wire to the frame because my engine bay is not like others More testing tomorrow!
HID Headlight help......
