How to connect JDM Headlight wiring harness to USDM Headlight wiring harness.
got my jdm headlights but when i test the usdm wires its like it switches polarity from hi beam to low beam, and i cant figure out which one is ground. Anyone have a quick fix for this? like wire color to wire color?
EDIT: Fixed at the bottom, now a how to with pics, thanks all!

the two thinner wires are what you want to use to get the low beam working. i haven't had time yet to figure out the circuit to get the fogs to work again... i'm using an HId kid, so i don't need to wire up the brights, but the fogs don't work just using the two thin wires. one is ground, one is positive, but it does't matter which you hook up to the H4 bulb, it will work either way. just make sure you are using the low beam filament, no tthe high beam.

Took this right after I got my JDM headlights,, see how dim my lows are,, fogs are clear b/c I took the yellow lens out. Make sure you get wire harness which can handle the output from a H4 bulb and not a generic harness like I got; reason why my lows are so dim. I found mine at autozone for like $4 for both of them. I havent installed my new harness yet, too lazy,, I just ran the wires on reverse polarity and aimed them way down so I would not blind anyone. This pic was b4 I reversed the polarity and found the correct harness to install. Installing my new harness this weekend while weather gets a little warmer. Wire socket from Autozone is PulseFX 84790.

Absolute, this was the picture I have been looking for. I have the same harness from autozone. The wires are kinda bunched together in your pic., so give us the verbal breakdown please.

Okay so thanks to some tips and help from you guys i got it down and done.
And i also used the autozone H4 harness PulseFX 84790, like said above.
Here is the right side, fogs, high beams and low beams all work
Here is the left side, fogs, high beams and low beams all work
if you have any questions let me know, and thanks to all that helped!

Cool that is exactly what i needed to see. Absolute you are always helpful and Jurassic your pic is exactly how i needed to see things. Thanks guys. Really didnt feel like playing switch the wires until they were right.

Hm would the h4 specific harness fix the problem I have?
Problem: Noticed passenger side headlight was dim. Decided to change both bulbs. After install, pass side still dim. I remembered it looked like a crappy wiring job was done on that side. Previous owner must have broken the oem wire harness.
Im thinking that its not h4 specific so it does not have enough power to run the battery at full strength.
Can anyone verify if that could be right?
