2G Headlight wiring fiasco!

[KOG_GSX]

Ok, here's the background: I took my projectors to a shop to get installed. They are the halo ebayers that do not come with connectors, instead, just run a pos and a neg from the bulb. Ok, so, I get into my car and turn the lows on, I see my high beam indicator (blue light in middle of cluster) is lit. So I pull back on my light lever and hear the click, but what do you know... indicator is still on. I get out to observe, only my low beams are on, no highs. "Weird", I thought. So I get home to witness what is about the dumbest thing I've ever seen. They routed the high beams and low beams wiring from the headlights into what I believe is the low beam connector, which consists of a blue/red wire, a red wire and a black wire, observe:

Observe the wiring in the bay, and notice how both wiring from the high's and low's are coming together in "sweet" harmony:

Ok, so here's what I've concluded. Since both the high's and low's are going into what IO believe is the low bea connector, oh, which by the way no longer exists... I think they snipped it off and gave it to God! Anyway, since they both run there, that's why the car thinks the high's are on when the low's are on, they're in the same place! Now, here's where I need to get some understanding. I looked under the stock headlight and noticed a connector:

I also noticed the wiring colors; 1 red, 1 green, 1 black. Now the pick below shows those same wires going into each respective bulb. The low beam has the 1 green, 1 black setup:

While the high's have the 1 red, 1 black setup:

So I concluded, the connector that the shop snipped off and sold to God must be the connector to go there and control both headlights Lo and behold, I look in the engine bay and see this connector just chillin:

Now, it's been a while since I've seen my harness setup, so I'm not exactly sure how it goes. So I need to see some pictures. On the stock headlight, there is only that one connector and both stock bulbs were connected to it via their respective wire setup. There is one connector on the outside of the bay, and the one in the bay. Which one connects to the headlight housing? Where does the other one connect? Why the hell are my high beams acting the way they are? How do I resolve this issue? I want to wire everything back up to stock because I will be doing my HID retro fit very soon and ordering my kit from sharphid, which is plug and play to the factory connectors. Please help.

Ok your wiring sounds so messy I'm not even going to try and figure it out. But you got me curious (and you sound hopelessly lost) so I looked under my '99 LF bumper area at the headlight connector to see the stock wire color setup which should help you.
The harness side has 3 wires:
(A) a red with blue stripe which is the power wire from the headlight relay (and becomes a black wire on the headlight assembly side which is power to both bulbs);
(B) a black wire which goes to chassis ground (and becomes a green wire on the headlight assembly side which is low beam minus);
(C) a red wire which goes to hi/low beam switch hi position, and hi beam indicator light minus, and momentary hi beam pull back switch on position (and becomes a red wire on the headlight assembly side which is hi beam minus).

Note that the hi beams are turned on by connecting the red wire to ground via the switch.

Actually I just deduced your wiring. There are 2 senerios.

Senerio 1 (most likely one): Connect the 2 projector blacks to ground. Connect the low beam projector blue to the red with blue stripe wire (power from headlight relay). Connect the hi beam projector red to the harness red wire. This makes the hi beam projector red be in series with the hi beam indicator light to +12V. Since the indicator light is much higher resistance, it does not allow the projector to get enough current (or voltage) to light but will light the indicator light somewhat (it's ground now being provided by the lower resistance projector). When the hi/low switch is in the hi position, it puts a ground on the projector (so it stays off since both sides are now grounded) but will light the indicator light to full intensity. So you can tell if it's wired this way by switching the hi/low switch back and forth to watch if the indicator light's intensity changes (and I bet it will).

Senerio 2: Projectors wired same as stock lights (one wire of each to the harness red with blue stripe wire, the other side of low beam to ground or harness black wire, and other side of hi beam to harness red wire). Then cut the harness red wire and connect it's harness side to ground (which keeps the hi beam indicator on) and connect it's headlight side to +12V (which keeps the hi beams off since +12V is now on both sides - or they could have left this wire disconnected). Note: If projectors are polarized the one wire of each to the harness red with blue stripe wire must be the non-black wire.

To wire your projectors correctly, wire the non-black wire of each to the harness red with blue stripe wire, the black wire of low beam to ground or harness black wire, and the black wire of hi beam to harness red wire.

Good explanation man, I appreciate it. One more question, what is does that other harness (in the engine) connect to?

 

[luv2rallye]

I'm not sure which connector you're referring to - pic 3 or pic 6?
What are the wire colors of connector in pic 3 and 6?
Also which side of the engine bay is pic 3 & 6 taken?
I suspect one/both of them are the original headlight harness plugs, especially if the wire colors are red with blue stripe, black, and red.

 

[KOG_GSX]

I'm referring to the connector in pic 6. The wiring inside the loom for that connector is white/blue, white, black. The low beam connector, which is the red/blue, red, black is pictured in pic one. That connector is sitting outside the engine bay. The connector in pic six is in the engine bay and there is one with the same wire color setup on both sides. I thought that was the connector for the high's, but when I looked under the stock headlight, there's only that one female connector.

Well I don't see that connector either in my car or in the book. See where it goes. If to another harness what else is on that harness? Your car didn't come from Canada (with daytime running lights) did it (I don't have those diagrams for 2g)?

You are still not understanding the high and low beam connectors: On the stock wiring harness there is only one 3 wire connector (red/blue, red, black) that goes to BOTH hi and low beams (it is not just the low beam connector). From that connector it splits into the green, black, and red wires (considered part of the headlight assembly) which go to the hi and low beam bulb connectors.

Negative, it's from here. I will have to trace it to see which harness each goes to, I'm just trying to think off the top of my head what two connectors can connect to on each side (and no they're not my fogs of blinkers.) Or maybe ask satan what connector has that setup (white/blue, white, black.)

You are still not understanding the high and low beam connectors: On the stock wiring harness there is only one 3 wire connector (red/blue, red, black) that goes to BOTH hi and low beams (it is not just the low beam connector).

Yah, my bad, I actually do understand that there's only one connector, I don't know why I referred to it as the "low beam" connector again. Anyway, I'll piece them back together the way you said and go from there. Thanks alot for the help man.

Hi,

Awesome thread but it doesn't work for me....look at the below pictures to see what I mean.

It's a Euro Version, German so it does not have DRL.

The reason, on picture 2, why I did Red to Red/Yellow was because I got 12V reading on the multimeter.

It started with just hi-beams on all the time, then I changed to red-red/yellow and consequently I only get low-beams.....switching back to red-red I still only get low-beams as seen on picture 3.

Clues? Please....

On the stock wiring harness there is only one 3 wire connector (red/blue, red, black) that goes to BOTH hi and low beams (it is not just the low beam connector). From that connector it splits into the green, black, and red wires (considered part of the headlight assembly) which go to the hi and low beam bulb connectors.

I just got HID Projectors.
Hooked the angel eyes into the sidemarkers, I'm happy.
The new headlights use my stock turn signal bulbs, whatevz.
My high beams don't physically light, yet it says they're always on in my cluster.

From my aftermarket headlight, it has 4 wires: red&black and blue&black. Blue is low beam, red is high beam, blacks are ground of course.

Your comment about the stock 3-wire connector that I had snipped makes me think I need to gut my stock housings for the high beam switch-thing.
How would I wire my high beams like stock, but in my new HID ebayz if I'm using said wires?
