Here's how to wire the 3-pin levelers:
- The power wire can be taken from any suitable +12V, parking lights are probably a good choice.
- The ground is another obvious one, just connect to a suitable grounding point. Again the parking lights ground wire can be used.
- The level control wire is connected to ground via the switch. The switch has 4 pins: 2 for the light bulb and two for the actual switch. Connect the level control wire to one of the switch pins and ground to the other one.
- Test your connections. In switch position 0 the resistance between the level control wire and ground should be 2700ohms. In position 1 it is 750ohms, 2=120ohms and 3=almost 0. Don't connect the lights when measuring this as they will influence the readings.
- Connect the lights and try the levelers.

People have sent me private messages with some questions so I better answer them for everybody:

- My car is Euro spec and has the leveling factory fitted. So I obviously have the real original switch. However, there are two kinds of the switch. The standard Euro WRX one has 4 pins: Two for the leveling system and 2 for the light bulb in the switch. WRX STi switch has 6 pins: Power, ground and 4 leveling control pins. For Morettes and other lights with the 3-pin leveling system you should use the 4-pin switch.

- The voltages I mentioned in previous post are measured with only one headlight connected to the system. If both are connected the voltages will be slightly higher as the control current comes from both of the headlights. Quickly calculating the voltages with both lights connected should be about 0=10.2V, 1=7.3V, 2=2.4V, 3=0.1V.

- I got the schematic diagram of the leveling system from a dealer so I'm pretty sure that my description about the connections (+12V, ground, control wire grounded via switch) is correct. The control wire is the middle one in the lights.

jahonen... is it possible if u can post the wiring diagram here?

i'm also confused about the different switches... is the standard non-sti wrx also a projector setup, or is it like what we have? i have the jdm sti hid lights and am not sure if i should be using a 4 pin or 6 pin switch.... part numbers for either would be appreciated as well because i'm still trying to find someone who can help order it

I only have the diagrams on paper and as they are faxed they are not very good quality. I'm afraid the small print would be more or less unreadable after scanning. And I don't have a scanner at home...

The Euro spec WRX has similar lights than the US model. The lights have the 3-wire leveling system (I understand that US lights have no leveling motors at all, is this correct ?).

STi:s and JDM models have the projector setup with 6-wire leveling system.

For the 3-wire system you need the 4-pin switch. For the 6-wire system you need the 6-pin switch or you can modify the 4-pin switch as described in this thread.

Sorry but I have no idea about switch part numbers.

h2o,

I don't know how the pins on the 6-pin switch are connected internally but you should be able to do this:

- Connect the +12V and ground pins on the headlight leveling connectors.
- Find the "common" pin of the switch. This is the one that gets connected to the 4 level pins in different switch positions.
- Connect the switch common pin to the leveling control wire on the lights.
- Connect the 4 level control pins to ground via resistors of so that the resistor values corresponding to switch positions are 0=2700ohm, 1=750ohm, 2=120ohm and 3=1ohm.

This would have the same effect on the control wire as using the 4-pin switch.

jahonen,

Would you be able to get your hands on a few 4-pin switches? Perhaps from a local dealer? Let us know what they cost and we might be able to set up a mass shipment. If you're willing to source the switches I can setup the payments and shipping here in the U.S.

Thanks!

Aaron

gabewrx,

Where did you get your switch? It looks like the 4-pin model that is needed for Morette headlights. It should wire up directly to the Morrette's as johnanen pointed out a couple posts up.

johanen,

Is the switch (4-pin) that gabewrx posted the same one you have as stock in the Euro WRX? If so then I think it should wire directly to the Morrette headlights.

Thanks everyone for all the info. I'm trying to find the easiest route to wire up my Morrettes with headlight leveleing capability.

yes. my switch is the same as his.
i got mine at the same time i got the headlights . i was in germany . visiting family. and i stoped by the subaru dealer. they sold me everything they even gave me the wire diagram for the headlamps... man i tell you those people at the subaru dealer are awesome!!!!..... much love.

since you are in MP, want to work on it together?
i believe you can get the leveling switch from nissan dealer

if memory serves, one of the infinity (QX4 i think) has a manual head light adjustment switch

TerenceT,

No problem, we can work together to figure this out.

I think someone else posted that the Infiniti QX4 had a similar switch in the dash. I called an Infiniti dealer's parts department earlier today, but they had no idea about the headlight leveling switch. I may be able to get the switch pretty cheap if it's a Nissan item.

Otherwise, it appears that the standard European leveling switch (4-pin, non-STi) will work for the Morrette's per johanen's experience. I also spoke with Vivid Racing today. They have a UK300 leveling switch listed on their website, but the shipment is not due for another 2 weeks. He was not sure whether the switches would be 4-pin or 6-pin.

I already have the 6-pin switch and may try johanen's method to wire it up with resistors. I won't have time to do this for another week or so, since I'll be out of town all next week.

I'll do some more research (hopefully the Infiniti idea will pan out) before I leave and try to source the correct switch to avoid excessive wiring.

Just got off the phone with Cerritos Infiniti.

The 2002 Q45 has a "Headlamp Level Switch" -- part #251905L300
$28.60 retail

It appears that the switch mounts horizontally, rather than vertically. I don't have the wiring diagram yet, so I can't tell whether it is a 4-pin switch or not. The technicians were gone for the day, so I might be able to get that info tomorrow.

This could be a viable option for us with Morrettes or other lights with leveling motors.

I've used a QX4 switch, it works, although, it will not have the right resistor values for Morettes. It has tiny resistors on it, similar to the ones found on computer cards. I adapted the switch to work with my STi projectors, although I was getting weird movement from the lights. Position 3 would be higher than position 2 etc. So I read that you need to change the resistors, tried that and got different movement. Finally I found out that you don't need any resistors at all, so last night I went to take out all the resistors, but from all the soldering and unsoldering the switch got ruined. Now I just want to find a 6 pin switch and be done with it. It will work and you can buy it at www.parts.com for $18 US. It's just a PITA to change the tiny resistors on it. It comes with a blue/white light so I changed it to a green LED. When you pop out the dummy plug you will see in the bottom right hand corner there is a little notch, if you want to use this switch just cut out that little notch and it pops right in, nice and secure. The resistor values will be way off for morettes so it's just as much work to change the resistors in the switch as it is to put new resistors in you 6 pin switch mca. If I had to do it again, I would just remove the resistors first thing and it would be a nice and easy job.

Infiniti Q45 switch, part #251905L300 is $18.65 at Auto Parts People
The Q45 switch mounts horizontally and uses a rotary dial -- Infinti Q45 switch detail

Infiniti QX4 switch, part #251905P600 is $15.00 at the Auto Parts People. The QX4 switch mounts vertically and looks like it uses a push button -- Infiniti QX4 switch detail

I may try to pick up the resistors today and try them out tonight or tomorrow afternoon on the 6-pin switch.

Does anyone know if the 6-pin switch has resistors in it? I don't have it in front of me right now (I'm at work) so I can't check.

I'll use this direction from jahonen and see what happens. Wish me luck!

Does anyone know if jimhoyd.com has "perfected" the harness for this that was supposed to be done fall '02.
Thanks

Still haven't had time to sit down with the switch and try to make it work. I might try this weekend, but time looks slim again. I'll post an update when I get it done.

I am wondering if there is such a cord with six conductors in it that i could use to make up the harness that goes from the passenger side light to the driver side through the firewall to the leveler switch?? I was wondering if some sort of phone cord had six wires in a outer sheath. Then, since I do not have plugs for the leveler motors nor leveler switch , I could use a 5watt soldering iron and solder the fine wires directly to the pins in the lamps/switch and finish the job with small shrink tube placed on ea. terminal before soldering. If this type of conductor is available it should be easy to tuck under factory clips and the sort underneath the hood for a clean installation. I allready have the adaptors from jimhoyd for the main light harness. Anyone think this will work?.
