i searched and found this diagram:


but i still have questions. is this diagram for an HID housing? because my harness doesn't have 5 male connectors, it only has 4 pictured below.

1. What does this brown harness connect to exactly?
2. in the picture above it says "top row 4th fuse from right"...what does this mean?



Also, i know from the diagram that the blue wire is the fog light. so, in the picture below, it has a weird looking connector...
3.does this just directly connect to the fog light bulb that i need to buy?




Finally, i bought these headlights off of someone, and it came with this SPW wiring harness pictured below:

4. i assume i need another one for the other headlight? (b/c i only received one)
5. Where do both ends of this harness connect up to?

 

the first few questions about the JDM headlights, i cant answer. if you find out, let me know. as for the wire harness, you will need another one. it is just an upgrade plug for the low beams. when you use aftermarket headlights, they tend to burn out fast, and fry the stock harness. this will prevent this from happening and make the bulbs last longer.
