I have seen a lot of threads on the one piece headlights already but I couldn't find an answer for what I'm confused about.

Anyway, the headlights came with bulbs which I believe are h4h. I notice they look a lot like h4.

I also have a plug that I'm not sure where it goes because it doesn't match my factory wiring harness.

Questions are, can I cut the h4 connection off a civic and match it to my factory wiring harness? As in cut and solder?

Next, where does this plug go?





And this plug which went into my original three piece headlights, I'm not sure where it goes. The smaller yellow one.
