Just buy a relay and use that much easier.
Wire it so the high beams activate the coil and also pass power through the relay to lows when in use.
Only problem there is when you flash you will flash the lows as well (based on reasearch some s14s do this anyway due to a problem with the contacts breaking down in the switch)
So get a 30amp 5 pin relay. (repeat for each side)
Pin 30 goes to the low beam projector
Pin 85 goes to the high beam power
Pin 87a goes to the high beam power
Pin 87 goes to the low beam power
Pin 86 to ground
Other thing to consider is that the load on the high beam wiring may be too much to run both sets of lights.
in that case connect pin 87a to the battery (important use a fuse).
That should work based on what has been said and what i know about s14a lights(quite a bit)
So you do that at your own risk.
