After staring at the FSM for European S14's for a while (they have DRL's), I have decided that my electrical knowledge cannot get me very far on this...Basically I want to have the high beams on whenever the car is running, but off when the headlight switch is on. Therefore, the headlights would act completely stock when the switch is "on" (lowbeams on normally, highs and lows BOTH on when flash-to-pass or high beam switch "on") but ONLY the high would be on when the switch is in the "off" position. Also, it would be nice if the lows would flash when pulling the stalk forward for flash-to-pass with the headlights switch off, for daytime use.

$10 paypal'd to the first person who successfully figures this out!

Anybody have any ideas? I think this would look nice during the day, much like Raine's lights:thumbsup :

BTW, I know he has JDM headlights...but I want to be able to do this to stock USDM lights.

...okay so you want the highbeams to act like running lights? and when you turn on your regular headlights or running lights you want em to shut off? Thats simple. Ill have a solution for ya tomorrow... im a master of wiring stuff to switches and messing with lights... the more i htink about it, the less it seems there would be a good solution to this. If you had fogs that would be another story.

while we are on the subject of wiring i would like to know the same thing halcyon does, but also how can i wire my fogs to be on all the time with my lights on ex. fogs on with running lights on, fogs on with normal lights on(already like that) and fogs on with highbeams on still, as well as fogs on with no lights on but the fogs, any ideas, sorry to kinda jack your thread.

I think all you would have to do though to get your highs to stay on while driving would be to wire a switch into the wires comin from the highbeams that lead into the stalk and then voila you got it, but im not sure if that will work or not.... so thats why i asked the above questions. If i can get the switch thingy to work ill let ya know free of charge.

Shaggy, to answer your question: Your situation is easier. Find the relay that controls the fogs, and wire it to your main ignition relay. That way, you turn the key, and your fogs are on.

Now about wiring the highs directly... as far as i can think of, that wont work because they will stay on even with the lows on, unless you can find a way to interrupt the current when you turn them on manually. Like they run all the time, but when you turn the parking/lows on, it cuts off the highs, until you turn the highs on yourself. Im not sure how to do that right off hand, but ill give it some thought.

Yeah, I was thinking the same thing. The interrupt part is what I couldn't figure out.

Oh and Shaggy, I have my fogs wired up to go on if I have my parking lights on, and they stay on when my highs are on. This is a pretty simple solution that has been covered a bunch. If you search, I'm sure you will find the thread on it.

ummmm with the high beams on it turns on the highs in the lowbeam circuit as well if you look at the bulbs in your low beam housing of the light, it has 2 filaments one for high one for low, he wants the bulbs in the high beam housing which only have one filament, (high obviously) to turn on when he turns the key on, oh and wiring it like that and eliminating the switch makes it so you definately one hundred percent dont forget to turn your lights off in the middle of the day if you just turn the switch on you could forget (i have terrible add ive forgotten before its not fun... and then on top of that after i pulled my batterie and charged it I was screwin it back in and i had started my car and left the door open and my alarm locks my doors as soon as the key goes in the ignition and a truck drove by and the wind from it and the breeze that was blowin shut my door.... go ahead and laugh i did it was funny but i was still really pissed, not a fun thing to have happen)

This is just a hypothesis, but what if I was able to utilize the way the fogs cut-off when the brights are on? I would assume that there is some sort of relay or something that causes this to happen. Anyone think that if I wired the high-beam's power, independently, through this relay, and used the headlight switch being "on" as the trigger (instead of the high-beams) that it would cut off the highs when I turn on my lights, like I want? Hmmm...maybe I need to look at the FSM some more...:eek3dance

you definitely need to add at least another relay. The combination switch we have is limited and it's basically missing another "off-1st-2nd" switch which is interlocked with "A-B-C" positions.
And like I said, you need the DRL module as well. I'll come up with the scheme if I have the time today.
