Default 94 firebird h4 headlight conversion questions

I just bought a parts car and pulled these headlights out of it. they use a h4 bulb rated at 100/90W. I am trying to figure out how to wire them making them work properly via high beam and low beam. here is two pictures of the housing and bulbs.

the wiring is an absolutely a mess that will be cleaned up by me or my dad (a journeyman electrician).

I would simply buy an H4 adapter harness. That's what I did and it took me maybe 30 min to finish because I had to extend the wires a bit. Should save you a lot of hassle and I would be careful going with that high of a wattage for an extended period of time without a relay or upgraded wiring. That wattage is way above the stock wattage so you run the risk of burning your wires. PM me for the vendor of the adapter harness.
