Clever. I realized what you did when I remembered helping Dance figure out why he had some irregular light output. He had the same thing occuring with a blown headlight fuse (for one side) except both grounds were not on at the same time so as a result, (I believe) the high ground was causing a 25%/75% light output.
Anyways, I am going to try this DRL mod with a weird set up. I have an 06 EX wiring harness with an attached external wiring harness which uses the left headlight's 12v power source as a signal source for a relay drawing power off of the battery and grounded to the chassis. So, basically whenever the main headlight switch is on, the low beams are on regardless. The wand now acts as an on/off for the high beams. I would like to obtain the DRL's for the high beams. The problem I have right now is that I can not use the feedback method you used for the non-SC so easily. Well, at least that's what I am going to figure out now.
Keep in mind I could care less how much I hack this thing up. :grin: Just as long as everything works... My brain is fried being 3 in the morning but I'm still thinking.
It's possible to have a wire run from the red/blue wire (or what I have now is the red/yellow 12v source on the left headlight) to control a relay which will switch between two connections which intercepts on the red/blue high ground wire - the original high ground and a new one which connects to a new DRL ground. The new DRL ground will have a resistor integrated to produce the dim lighting effect and grounds to the chassis. Right now, that wire is serving as a signal source for a relay controlling power input from the battery to low beam HID's grounded to the chassis. So, one signal wire (red yellow most likely) will serve to control two separate relays. Have a wire run from the V connector which will provide the signal source for a third relay which turns on/off a 12v power source from the battery to the high beam bulbs. This means whenever the key is set to the right ignition setting, the high beam bulbs get power and whenever it's off, they don't. In effect, what this generates is the following effect in theory:
Always true:
Headlight switch on: HID's are on
Headlight switch off: HID's are off
Car ignition off: high beam bulbs have no power, always off
Car ignition on: (high beam bulbs have power)
--If headlight switch is off:
-------Wand is in low beam position: DRL light effect
-------Wand is in high beam position: DRL light effect
-------Wand is pulled towards driver: HID's and high beams are on full effect (bad side effect)
--If headlight switch is on:
-------Wand is in 'regular' position: HID's on, high beams off
-------Wand is in 'high beam' positon: HID's on, high beams on full effect
-------Wand is pulled towards driver: HID's on, high beams on full effect
If I theorized correctly (now being 3:40AM having been up since 8:30 AM the previous day) that should work and work well with near proper functioning. Unless I messed up reanalyzing what I wrote, that should work. Thoughts? Errors? With the current set up, its pretty much unavoidable with out major hackwork to prevent the HID's from coming on when you pull the wand towards you. I'll live with that since that's how it is set up now. I'll have to figure out what resistor to use and relays assuming that my resistor ground will work. It should given the nature of the original set up. Just have to wire the high beam ground wires in sequence to mimic the effect. Same goes for the power source. It's going to be an interesting new wiring harness... I think that's the best part: it can be made so it's completely removable with out altering the original set up!


(I just realized this, final edit at 3:45.) Well, aside from running the single wire from the cabin which at that is technically not a permanent alteration if you don't damage anything in the process. So, yes it's completely removable with no negative side effects for future application. That's kind of nice to know. For whatever reason I can just swap out the DRL /HID harness for a regular 1 relay HID harness or no harness and just have regular halogen bulbs. Having options is nice but to me this will be permanent.
I'll need to come up with the proper wiring set up but this set up will work for anyone who has a non-SC who converted to an SC front end with out changing the wiring harness and wants high beam DRL's. More or less anyways depending on whether or not they grounded the low beams to the chassis.
Edit: added the updated picture.
