Some of the newer cars come with automatic operated lights using a daylight sensor. The idea is, if you drive at night or in a tunnel, the lights work without you either remembering to turn them on, or afterwards, off again.

My KH Verada warrants this feature as it was fitted with the High Contrast instruments which are always backlit, and at dusk, I forget to turn the lights on, also I would prefer the lights to be automated (me being very lazy).




YOU WILL NEED FOR A 3rd Gen

- Headlight Commander Unit (Supercheap $29)
- Assorted Wiring
- 2x 12v SPDT Relays (DSE - $6.49ea) PN: P8035
- 2x Relay Base Harness (DSE - $1.94ea) PN: P8036 (optional)
- 1x Good Quality Switch (Repco - $5.99) optional
- 1x Multi Meter (DSE $10)
- 1x Endless trip to find a $6 battery for the $10 Multimeter!!!!
- Assorted Plugs/Connections are YOUR choice! But are handy.

This is a simple mod as all of the “working out” has been done. However, depending on how professional with the wiring you are this could take from 2-5 hours.

The Headlight Commander works by getting a single power source, and using the sensor as a switch, sending power 12v+ to the park & headlight relays. Unfortunately, the relays in the required list above are needed because Mitsubishis are wired so that the Column switch earths the relay power to get the lights to work.

STEP ONE – Sussing out Wiring


After downloading the Tech Manuals (http://www.aussiemagna.com/forums/showthread.php?t=56815) and removing the drivers side kick panel and the steering columns surrounds, unplug the headlight/parker Col. Switch Plug as per the picture.

The car photographed is a KH Verada Xi. So if you don’t have as many plugs there, it’s because my car has fog lights etc.

Check you have the right plug by unplugging it and testing the lights. You high beams should work but the low/parkers will not.

Get a Multi-meter/Test light out and find two of the wires which have power when the switch is off. In my car, it is the BLK/Red Stripe (parkers) & the RED/Yellow Stripe (headlights). Included is a wiring diagram for both a Magna & Verada (http://www.box.net/shared/gq8nitsm42) (Head & Park lights) to check the wire colours.

STEP TWO – Installing the Sensor & the Unit


After the above, its best to work out where you want to install the box & sensor. I placed the sensor next to the climate control sensor in the front/middle of the dash. To do this I removed the air vents using a fabricated tool, (grind a very long screwdriver like below as it looks/work like Mitsu’s version) and also removed the trip computer.

http://i405.photobucket.com/albums/pp136/mcstannard_bucket/DSCF2051.jpg


You can then get a hand in to pop up the climate control sensor & unplug it.

I then used a bit of adhesive to hold the new sensor in place and ran the wire down the side of the stereo. I chose to install the box onto the frame next to the stereo as it will not rattle, it is close to the sensor wire plug and is out of the way.
A Top Tip is to zip tie and tape the unit so it will not rattle against anything as well as taping down the plugs.

http://i405.photobucket.com/albums/pp136/mcstannard_bucket/DSCF2054.jpg


After securing the unit I placed an illuminated switch in the kick panel as below:


I have wired this switch with a plug so if the kick panel is removed, the connections will go to the right place. The switch has 3 connections. 1 for power in, 1 for power out and an earth. When power is being supplied to the headlight unit, the light is on. This switch allows me to override the Headlight commander if I want to or if it fails etc.

STEP THREE – Wiring the Unit In


As the unit is installed, the only thing left to do is install the wiring, place the relays and plug it all in. With the wiring, Crimp or Solder is YOUR choice.

After using the Wiring Diagram (http://www.box.net/shared/70cx4u15d8) to sort out the connections, I fabricated a loom which is sealed & plugged. Basically all the connections to the existing wiring in the car will have a plug on the end and the new loom will connection to it. As the new loom is zip tied/taped to the existing wiring, the install looks as factory as possible, better I think than the ‘pro’ install for my Head Unit. If this is the direction you choose to take, make sure you wire enough length to get around various obstacles in the car.
http://i405.photobucket.com/albums/pp136/mcstannard_bucket/DSCF2055.jpg


TIP- PLEASE check with a multi meter for continuity in the circuit during fabrication and installation. This is done by using the OHM (horseshoe) symbol on the meter. If your luck is anything like mine, you will have (as I Did!!) a single wire which will not work and it will be at the back, taped up, and dark and you will swear.

TIP -Again, a Top Tip is to get a light coloured tape or sticky thing and label loose wires during the loom fabrication. It makes it really easy not having to trace wires when making a plug end!!!

After this, all that’s necessary is to connect the loom to the power & earth points of your choice.

I USED:
Red/Yellow Strip (Headlight Relay Power);
Black/Red Strip (Parklight Relay Power);
Blue (pin4) Power Mirror 12Vin (Goes to the Switch for headlights to work ACC mode)
Various Earth points around the car. Connections should be free of paint and direct to the chassis.

STEP FOUR – Reassemble & Admire


This is the finished install. Only the switch & the sensor top (vaguely) are visible for this mod and it is extremely useful in my opinion.

TIP – Make sure you do the wiring well. Use quality connection and take time. I can tell you the absolute LAST thing you want is to have to repair it after it’s a week old.

Now, after reassembly, final test but putting a small piece of black electrical tape to the sensor, (because after all the fiddling with wiring, you fingerprints are gone and using your thumb will make the dash bloody) your lights should come on after a slight pause. If this does not happen, swear, and then calmly repeat instructions from beginning.

Please PM me if you need further info


I would like to extend my thanks to the brilliant AMC member who has provided endless help for me with the many obstacles to be overcome. You know who you are, and without your help, myself and the rest of the members who use this guide would not be able to benefit. So THANKYOU. IF you ever need anything, please do not hesitate to PM.

In addition, to any AMC’ers who have provided input into any thread regarding this topic, cheers. Generally with this forum, any post is usually worthwhile. Especially in this case.

It would seem that the extra green wire supplied with this box is useful after all!!!


Mike481050 discoved that this wire should be connected to the power supply for the Magic Headlight Box Thing (Technical Abbreviation MHBT).

As I had previously stated it is not to be used, I apologize to any confusion/inconvienience this may have caused.

Just for clarification, the green wire mentioned is part of the loom supplied with the MHBT and finishes BEFORE the supplied plug on the MHBT end of the loom. CONNECT THIS TO THE RED WIRE and all will be sweet.

And a VERY LARGE thankyou to Mike481050 for the updated info. Yet another personfication of this forum being worthwhile

If at any time you have issues with this, shoot me a PM and ill give you a hand.

Also, I am adapting this unit to work with the indicator stalk with 'Auto' position. If it all goes well, Ill upload a new wiring diagram next week to suit.

If you have any photograph requests in addition to what is above, let me know as I'm doing another install of this tomorrow and will be able to take them.

I'm trying to install it with the indicator stalk with 'Auto' position too! I eagerly await ur results mate! Do post the new photos!

Quick question... might need help with the wiring loom part of things. I'm a newbie at all these things, so might need ALOT of pointers... LOL

Oh i don't see the picture for the grinded screwdriver thingy... i broke one of the vent clip removing it by hand... damn! Need to make up one of those special grinded screwdriver.

Maybe i need to drop by the expert!

look to the left of where you got the headlight commander. There is an auto light sensing turnon right next to it for $22.95!
Edit. I am on my phone. So if this has already been said. Sorry

Ok,

So after today's effort, the headlight stalk with the 'Auto' position works very well with the headlight box in this DIY.

A slight modification of the wiring diagram was necessary, and if enough people want one, I can upload a modified wiring diagram later this week.

But the system works extremely well with the Auto stalk and it all looks factory.

Thanks to Mike for installing my auto lights yeasterday.
Now looks like it was there all along.
Pics of the factory look Here (http://www.aussiemagna.com/forums/showthread.php?p=1125411#post1125411)
All the wiring was incorporated into the factory loom system making it very hard to pick up.

Sorry to drag this back up, but by clicking !!!!HERE!!!! (http://www.box.net/shared/9rlttruxf1) you can access a wiring diagram so the system can be used with the now more common headlight stalk with the 'Auto' position.

Sorry this took so long Mr Roberto.

Hi,
What a fantastic idea!
I'm reading about the Headlight Commander Unit and have a few quick questions:
Where do you buy the unit? I've checked Supercheap in Melb and they don't stock them
and
Where can I buy and how much for an indicator stick with the Auto function (and fog light)

Cheers
Rob

Mike, You're a legend.
I have one of these Auto headlight stalks in storage - I may now have to do something about getting it fitted.

My wife's car (Honda Odyssey) hs only two things I wish the Ralliart had.
1. Auto Headlights (this will fix that)
2. Heated Seats (:think: lol)

How does the climate control sunlight sensor work and does it switch? Like to keep the stock look of my car no matter how small the change is.

Get a power inverter and stick a highly flammable bar heater under each seat ? simple lol !

The climate control snesor on top of the dash is a day/night sensor. It works exceptionally well too for the climate control. The thing is, while sensor may be able to be used, for the NZ JDM cars, the body computers read the signal. So you would have to install the JDM body computer to get it functional as a headlight system.

It cannot be incorporated into the aftermarket system as far as I know. If I were you, and wanted a clean top of the dash, I would mount the sensor (which is the size of a pea) in one of the airvent holes for the windscreen outlet. Silicon the hole you made to get the sensor in the underdash vents and it will be hidden.

My current sensor is a windscreen mounted one with a cord that is now incorporated into the chromatic mirror tube thing. The sensor mounts the windscreen behind the mirror and looks like anyother factory light/rain sensor. perhaps that would be an option.

Also, just to add because I have recieved a few PM's/

I'm going to check, when I have time, my local Supercheap places to see if this box of tricks is still being sold. A few members have told me they cannot get them.

The 'Auto' position headlight switch/stalk is easiest to get from NZ. Many many JDM cars live in Kiwiland now and they all come with this stalk. Also ALL of them have the foglight switch on the stalk too.

Oh and I'm looking into the heated seat option Puck.

I checked supercheap locally today and can confirm that these headlight commanders are no longer stocked. We cannot win them all.

It not the exact same unit but it has the same function :) It would be the same way to wire up.
