 DRL's to switch on at night:
 
It took quite a bit of wire probing under the main fuse/relay block in the engine compartment to find the wire which activates the DRL"s.
 
This mod I am sure will void the warranty but unless someone is actually looking underneath the electrical box, they will never see it. Please do not attempt this unless you are VERY competant and knowledgeable in electrical  systems and using a multimeter.
 
First you will need to remove the bracket which is just behind the electrical box located in the engine compartment and on the drivers side. This bracket will prevent you from removing the electrical box housing. Once you have removed the 4 bolts on the bracket and the bracket itself, Lift off the cover on the electrical box and then lift off the housing by pushing in the 2 clips facing the engine.
 
On the engine side of the electrical box you will see pivot points where the whole assembly can be rotated after you depress the locking latch which is up against the fender side of the box.
 
Now rotate the assembly towards the engine. You want to be able to get to the underside of the electrical box.  When looking at the undersides, you will see a green square module, a Red square module, a black rectangular module and a White recatangular module.  I have a phot on my photo page to show you what it looks like.
Locate the lower right corner of the Green Module which will be directly above the Red modue. The lower right corner of the Green Module has an unused pin which if a wire was attached, (I attached a red wire) will provide 12volts when the ignition is on. Directly above this is 2 blue wires. These blue wires are the power control for the DRL's. If you cut these wires, the DRL's will not work at all. If you cut these dual blue wires and install a toggle switch then you can shut them off when they are on.  
 
I have wired mine so that I took power from the unused pin below the blue wires (Installed Red Wire) and ran that to a switch and then back from the switch I then tapped into the blue wires. So if I leave the switch on all the time, It is sending 12v to the blue wires which already have 12v if it is day time and thus not doing anything different  and the DRL's will still remain on. At night when the DRL'S would normally be off, if my switch is still on, it is still sending 12v to the blue wire which keeps the DRL's on. When I turn the switch off, The blue wires are still receiving 12v from it's normal source during the day and the DRL's remain on but when it get's dark and the DRL's normally shut off, they are no longer getting the 12v from my switch so they remain off until I switch them on or are switched on automatically during the day.
 
If you simply want full control of the DRL's then cut the blue wires and supply your switched 12v to the part of the cut blue wires which are tied into the wiring loom and leave the other part of the blue wire which is going into the Green module taped off.
 
I am in no way telling anyone to attempt this. If you understand what I have done and it makes sense to you then you can do whatever you want.
 
 If it is a bit confusing, please don't  attempt this because you can fry your electrical system if you tap into the wrong wire.......


I wasn't interested in the switch, I'd be happy if they were on all the time.  Upon careful examination, I performed this task,  
 
Using the info gained from the above link, I removed the 7mm bolt in the middle of the green connector block.  The green block pulled out of the assembly quite easily.  There is a blue assurance clip that slides into the sides of the green block.  I removed the blue clip, removed the pin that the two blue wires are connected to, re-inserted the pin with the blue wires into the empty hole in the lower right corner. (Where the red was placed in the above post).  I put the blue assurance clip back in place, put the green block back, tightened the 7mm bolt in the center and put the whole assembly back together.  My DRLs are always on now! Yahoooo!  (Except when the high beems are on).
