doing kouki front end onto a 95 s14, cant get the headlights to work right. i can only get it to turn on the low beams, then turn on the high beams. i cant get the low beam to stay on when the high beam is on. can somone give any info? there is 3 wires comming off the zenki harness and 2 off the kouki projector.

after more experimenting, heres some info.
putting kouki s14 lights into a car with a zenki wiring harness. high beam is direct fit. low beam on zenki had 3 inputs, one ground, 1 low beam power, and 1 high beam power. kouki lows only have 1 power, 1 ground.
so the problem is, when i hook both power wires from the zenki harness to the kouki projector, it powers the high beam as well, which i dont want. but i have to have that wire getting power from the low beams, or else it will not power the low beam when the high beam is on.
i can disconnect this wire, making only the low beam come on when switched to low, only the high beam come on when switched to high, but id prefer to have full functionality.
there has to be a way to do this without buying a relay? so many people have done this converison sombody has to know what to do.

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.

this method works. The only reason why I cross the wire over is because When I do have the highs working, only one High would work.
This wiring will keep the Lows on when Highs are on. this is OEM style. But the only downside do this trick is when you Flash the highs, the low would flash too. pretty obvious from the wiring. the kouki uses a different wiring layout, it has a double switch. You can compair it in the FSM. There was actually a thread on this a few months back. If you want it truely like Kouki, you need to swap over the relay they use and wire it up like it should be.
edit: even though you do get the Kouki relay unit, it still wouldn't work. I think the actual headlight switch is built different. I even took mine apart and couldn't figure out the correct contact for this. the design on the zenki is to power both high and low on. Being that high is also on the low side.
You should do the aftermarket relay method above. It shouldn't be too hard. Just locate the oem headlight relay and pin out the wires and go from there.

Cookie's method is correct. The switch is the same for both models, the changeover is that the Kouki uses a DPDT relay to run the lowbeams whereas there is nothing like that in the Zenki. Adding it as described works fine.

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

That didn't work for me. This how I did it:
Pin 30 goes to the low beam projector
Pin 85 goes to the high beam power
Pin 87a goes to the low beam power
Pin 87 goes to the high beam power
Pin 86 to ground
On the relay power is on 87a when relay is not powered, therefore I connected low beam power to pin 87a. When I turn on my high beam the relay has power and make a connection to 87. So both my low and high beam are powered. This works for me, I don't know if the connections of Dutch S14's are different from UK ones...
