I tried searching but the only things i found didnt answer the question, so im putting it up here. What are the 3 prongs on the back of the headlight which one is what. I am not sure since it didnt come with a plug.
Also I am looking for the sir jdm bumper filler piece for a friend if you have one let me know. https://honda-tech.com/zerothread?id=1941794

is there a certain prong for the lo beam, high beam, ground or does it not matter.

Yes it matters. Use a test light or a multi-meter to determine which wire is what by turning your headlight switch on and measuring at the plug.

I dont remember off the top of my head just get 2 lengths of wire, crimp some spade terminals on the end, then connect to your battery, hook them up to the prongs on the back and see what happens you will figure out the high and low and ground, they are the same as a regular H4 so if you can find out what pins are what they are the same as a h4h. If I remember correctly the ground is on the left the center and right are for high/low. you will also have to wire in a relay. so the bulb doesnt have the low and high filament on at the same time, your bulb will burn out super fast this way.
for the relay
hook 85 up to the high beam power(spliced, power will still go to the high filament as well) . hook 86 to the ground. cut the low beam + wire and hook it to 30 , then hook 87a back into the low beam wire going to the light and leave 87 blank. when the high beam is switched on it will cut the circuit from 87a to 87 and thus turning the low beam off
