Manual leveling switch on restyled Lancers (2011+)

[JaymeF12]

Some lancer models / years are missing the 3 main pins that allow the factory HIDs to be levelled inside the vehicle. Mostly missing from the 12pin headlight harness to inside the c-131 connector.

For this to work you need 2x harness plugs (A-41 & A-56, these are 6 pin plugs, i got mine from a 2009 VR lancer), Pink (or red), yellow and brown wire (these follow the restyled OE wiring diagram) 1x fuse tap and optional 3 pole weather proof connector (You can use the 3 empty pins in the 12pin harness if you want) the OE manual level switch (Can be taken from an ASX) and split convoluted tubing

You will need to remove the interior side panel on the left hand side, the panel which holds the Flare. From there, there will be multiple plugs, you will look for C-131, a 20 pin plug which will have a lot of wire missing on the male connector. Located Pin 4 and 5 (Yellow and Brown) Yellow is the signal wire coming from the C-134 connector (connector which plugs into the manual leveling switch) which will be going to both sides of the headlight 6 pins. Brown is the 12v wire. (The c-134 connector is missing a 12v power source at the switch, you can grab it any way you like) (I found that any of the female terminals from an hold head unit harness actually fits very nicely into the OE connectors, and you can cut the old head unit wires and use that)

There will be a large grommet located near the area you are working, remove that and make a hole big enough for the brown and yellow wire to be fed through. Tape it up with electrical or cloth tape to make it look nice. You will then need to remove the passenger wheel and wheel liner to locate the exiting grommet, remove that and make a hole for the wires to go through. Once you have done that, look further up and zip tie the harness to the OE side indicator harness there to keep it safe.

You will run the brown wire into the fuse box and add a 10a add-a-fuse to the 10a HALOGEN / AFS fuse, its the top 10a fuse. This will give power to both HL motors & and C-134. From here you can also add 2x red/pink wire from there to each headlight only when the headlights are active, not on ignition. (I have 3x wires coming out of the add-a-fuse, 2 red/pink and 1 brown). Then you will run that wire, strip and crimp the end and add the terminal to the pin (for OE pin out, pin 9 is the 12v power for the motor)

Next you will want to, depending on how you will pin it, grab your weather proof connector and add the terminal connectors onto the end of the yellow wire ONLY and insert it into any of the three pin points on the weather proof harness (if you are following/using OE connector insert into pin 10, you can find pin 10 as on the bottom row of the 12pin there will be two wires occupying pin 7 and 8 and then a gap of three, then pin 12 occupied) Then strip back some insulation further down the wire, pre-terminal connector and add more yellow wire( SOLDER IT ON, this will also send the signal to the driver headlight)

Tape the red/pink and yellow wires together, look at the firewall and there will be a harness that is following there, layout the wire along there, ensuring you have enough length to get to the driver side, once you have, FEED THE WIRE INTO 10MM SPLIT CONVOLUDED TUBING and ZIPTIE IT TO THE HARNESS. Once you have done that, the driver side 12pin pinout follows the same as the passenger side (First side / HL OE connector, pin 9 is 12v, pin 10 is signal/yellow)

Once you have done that, grab your 6 pin connectors you have robbed from a wrecker and it follows like this, RH 6pin BROWN = 12v, GREEN = Signal / yellow and RED = GROUND, LH 6pin BROWN/WHITE = 12v, ORANGE = Signal and BLUE = Ground

solder the corresponding wire colors to that so, Brown & Brown/White needs that red / pink 12v power, Green & Orange will need the yellow signal and then for the ground, you can ground it to any good vehicle chassis ground. (Slide some heat shrink over the wire before soldering, makes it look a bit nice) (FOR OE connector, PIN 11 is the ground as per the wiring diagram)

I can attach photos if needed of how / where i ran everything.

I've attached a VERY MESSY MS paint wiring diagram
