Years ago I was able to find a schematic on how to do the one piece headlight conversion. It showed the relays and wiring all in one diagram. I haven't been able to find anything like it this time around. It was setup so that I could use one light as low and high beams, use the yellow inside bulbs for fog lights and the corners as corners. All I'm finding is people butchering their stock harnesses just to get light. Please someone help me out with this.

 

here's a super simple diagram to wiring the H4 plugs properly (i.e. so the low beam filament turns off when the high beam filament turns on.) you will need to SPDT relays, one for each side of the car

as for the old high beams being ran as fogs, you'll need a fog switch, fog relay, then you can just tap the pre-wired fog light wires (blue electrical tape below the head lights) all fog wiring has blue tape on it.

 

You don't need any of that - PasswordJDM and a few other places sell jumper harnesses.... they have for years. Plug and play.
