Ok, I need help:

Has anyone installed JDM headlights in their 4th gens? I'm trying it with my brother, and I've hit a stonewall:

we've removed the bumper, corners and USDM lights, but I can't install the JDM headlights because there's a difference in plugs and bulbs --

The USDM has:

outside bulbs - low beams
inside bulbs - high beams

the JDM has:

outside bulbs - high/low beams (dual fillament)
inside bulbs - driving lights (can't be high beam or headlight, bulb is too small)

Right, now the connecters from the USDM bulbs will not fit the JDM connecters, and vice versa, furthermore, even if I could connect them, the inside USDM bulbs (high beam) will not even fit into the small hole for the inside JDM bulbs. Also, I don't have the JDM "wiring harness" , all I have are the plugs that go into the JDM bulbs, and an inch or wire leading out. How can I do this? Obviously I have to keep the JDM bulbs because my USDM ones won't fit into the hole on the insides. But, since the JDM outer bulb is meant to be low and high, and on the USDM car, the insides are high, when I hit higm beams (assuming i've soldered wires from the USDM harness onto the JDM plugs), the inside driving lights (JDM bulbs) will come on, not high beams, and when I turn the headlights on, will the JDM outer bulbs be on high, or low, and how can I select one or the other? Please help, I have a helluva lot of studying to do today, and my car is in the garage, with bumper on floor, with headlights out. Thanks.
