Stock 2IS w/o(LED), DRL not disabled, install the kit from Sewell:
0: DRL Halogen (no LED)
1: DRL + LED (100%) + Tail Lights
2: Low Beam HID + LED (100%) + Tail Lights
3: Auto

Stock 2IS w/o(LED), DRL disabled, install the kit from Sewell:
0: Nothing on.
1: LED (100%) + Tail Lights <--- This is how people turn on the LED's during the day
2: Low Beam HID + LED (100%) + Tail Lights
3: Auto

Stock 11-12 2IS w(LED), the way it works from the factory when the car is off:
0: Nothing on.
1: LED (50%) + Tail Lights
2: Low Beam HID + LED (50%) + Tail Lights
3: Auto

Stock 11-12 2IS w(LED), the way it works from the factory when the car is running:
0: LED (100%)
1: LED (100%) + Tail Lights
2: Low Beam HID + LED (50%) + Tail Lights
3: Auto

If you want the LED to come on by itself when you start the car without having to turn the light switch to 1 or 2, you will need to do some custom wiring to get power to the LED strips while the car is on (either from an accessory power source, or similar).

Important note: For Canadian models, DRL cannot be disabled in the computer. There are 3 good ways to get around this:

1. Replace the body ECU with a USA-spec ECU so that you can disable the DRL's.
2. Replace the MPX ECU with an 06-10 Euro/Japan-spec non-DRL ECU, or 11-12 LED DRL ECU, this will disable the halogen DRL.
3. Wire in a relay so that the high-beam halogen bulb only gets power or ground when the low beams are on.

I went with the 3rd choice, as I had already modified my car's wiring to run almost exactly how the factory 2011-12 cars do (my DRL's are on whenever the engine is running, but are not tied to the parking brake like the factory setup).

There are a few different types of stock HID projectors in the 2IS. The 06-08 and 09-10 are not the same, they have different cutoffs. I had stock 06-08 headlights, then 06-08 headlights with STi-R projector lenses, and then now stock 2012 headlights. The 2012 headlights have a better (lower) hotspot location and I find the light output better than either of my previous setups. The cutoff is obviously not sharp like with the STi-R lenses, but I found that to actually be more distracting than the soft cutoff of the factory lenses. I have never run any 09-10 HID projectors and cannot comment on them, but I believe them to be almost identical to the 11-12 projectors, they have a much more gradual step than the 06-08 projectors.

I've seen your pics of the stock output versus the S2000 output before CCJ22, but unless I'm missing something I don't see any pictures of any older projectors.

You've said it many times that you think the 11-12 projectors are inferior to the 06-10, but having worked with the 06-08's quite a bit, I can say that I respectfully disagree. What I think we can agree on, is that there are many much better projectors out there, and your new setup is a very nice one. I just can't bring myself to run a rear-mount bulb projector due to the modifications required.

Terminal 30 goes to your ignition power source, 85 goes to the low beam +12V wire, 86 goes to ground, 87 goes to the 50% power on the LED strip, and 87a goes to the 100% power on the LED strip.

This will have the LED's at 100% when the car is on with the headlight switch in position 0 or 1, they will drop to 50% if the headlights are turned on (low or high).

Would you use one Relay on each side.... ??

How would I skip Position 0 ?? Meaning I only want them to work like this:

LED's wired with Relay

Position 0 = Off
Position 1 = @ 100%
Position 2 = @ 50%
