OK, so I have a set of headlights from an 02 STS, a car that is no longer with us (rip). I am trying to hook up the HIDS in my 01 sls with little luck because the connector is different. Is there an adapter that I can use or will I need to rewire it myself? The sts had the square connector and the sls has the circle connector.

there were some electronics/electrical changes made starting with the 2002 model year -
for example - none of the radio systems - including the 6-disc CD changer -
from a 2001 and older Seville will work in a 2002 or newer Seville -

looks like they changed the headlights also -

........ and I think the focal length for the HIDs and halogens is different - both for the low beam projectors and the high beam reflectors.

Different focal lengths = different light patterns = out of focus.

Here's the 2002 Seville halogen assembly ..........

I have the entire assembly for the HIDS and they bolt in, my only problem is the wiring

I've dabbled in this and my suggestion is to not do the stock HIDs. They use the same ballast that I had in my SRX. At least in my SRX, that ballast was constantly getting water in it and shorting out. I think we went though 4 of them; almost one every year. It could have been water getting in the headlight and running down the wires, I never figured it out (though I did buy a new headlight enclosure to try and fix the problem). I do know that the ballast units are not sealed and the way that I fixed it was to take a ballast from a newer SRX (it was sealed), and then make my own connectors that were soldered in and filled with gasket maker.

As for my Seville, I've played with the aftermarket HIDs from a lot of brands and I would highly recommend picking up a Morrimoto branded kit. I think it puts out the same power as the factory kit, it doesn't flicker, and the bulbs will fit without need to modify the housing. The downside, their bulbs don't stay 100% effective their entire life like the D1S HID bulbs do. If you are like me, you will get annoyed and replace the bulbs once a year. Oh, and I had one of my Morrimoto ballasts go bad inside the first year of ownership, the warranty process was a piece of cake.

And to Sub, you may be right about the focus of the projector being different. For what it is worth, I did a test with the spare 2004 SRX headlight enclosure (stock HID version) and ballast that I had. I compared it to the one from my Seville (stock halogen). I wasted a few hours in my garage with the lights out of the car and swapping bulbs and enclosures. I found there to be no difference between the focus at ~15 feet. I may not have had enough space in my testing at 15 feet, but it was enough for my peace of mind. I wouldn't be shocked if GM tried to save some money and just put the HID lens in all the cars back then. If it is different, in my opinion the lens wasn't different enough to justify sourcing one from a factory HID assembly.

That oem ballast will hook up to your stock headlight harness and work fine. I should know as I fiddled with lots of aftermarket and hid kits with my car. I would highly recommend you use an relay harness for the hid kits. With that being said, an aftermarket 6k hid kit is much better than the oem kit Imo, much more light output. There were 2 different oem ballast for the Seville, a huge Philips ballast and the smaller ballast which was the older one. I have 2 oem kits and an aftermarket kit. Check out one of my older threads I made a while back, it can be done easily, but aftermarket 6k is the way to go imo. The oem kit is sitting in my back window unused anymore...

And the projectors in an non hid Seville will work fine with hids without blinding traffic.

Of course I read the whole thread. If you read my reply u will seethat I mentioned that the on ballast WILL hook up to the stock harness with the 9006 bulbs. The first thing I noticed when doing my swap that the actual harness connector was different, duh... I'm stating that the connector (9006 for the ballast) will connect to the oem harness, also 9006. I hope I'm being clear enough.....

This is what the harness to ballast plus look like, not 9006. Any idea what kind of plug it is?

Back to what I had mentioned about the SRX in post 5, I replaced that ballast with the one used in the newer SRX (I got the idea from an XLR post here). I found that one of those pins is unused, I can't remember which so you are going to need to mess with a meter.

Back to what I said before, using the German-made OEM ballast is a really bad idea. They are not sealed and you will very likely go through all this work, only to have a water problem some time in the next year. On top of it, the light connector on the halogen lens is keyed for 9006 bulbs, not the D1S that the OEM igniter will connect to. These two types of bulbs are very different. Really, save yourself a lot of headache and get a good aftermarket HID kit. I'm sure that there are others, but the Morrimoto ones work very well in the Seville and won't flicker, the bulb will connect to the housing that you already have.

Yeah I do remember having to create a bracket to get the D1S bulb to fit in the lens. BTW, my Philips ballast is the same as the picture, on mines, the connector goes into the ballast and you hook the 9006 into the other end. So idk if they sold an adapter to make 9006 hook to the ballast, but that's how mines is. That's why i mentioned that I was able to hook my 9006 connector into the ballast. I will post a picture of the ballast and connector once I go back down to the car.

I understand that it isn't the best setup, and aftermarket kids would be ideal. The thing is I had aftermarket HIDS, 9006 6K HIDS. I used them in my other car when I had to set the caddy aside for awhile and am trying to get this setup to work with the stock HIDS only because I already have the ENTIRE setup with the working d1s, the headlight assembly, and the ballasts. Whether the ballasts are poorly designed or not I really just want to use this setup until I can afford to buy a new set of aftermarket HIDS.

I'mo I don't believe the stock kit a poor design, i just think the light output is not as good as 6k aftermarket kits. I recently had 6k headlights and fog lights but I changed my set up as I believe the car drew way more attention in the wrong ways (idiots trying to race and police that seem to not be able to take their eyes off of me). I decided to throw the oem kit back on along with going back to the halogen fog light bulbs, and I paired a good relay harness to both lights. I noticed on my buddy's STS, if he uses the turn or hazard signals, his fog lights would blink if you looked closely, with the relay harness, there's no blinking at all, and the hid ballast powers up much quicker which is why I recommend using a relay harness regardless of which kit you decide to use.
