Xenonk Posted August 15, 2004 Share Posted August 15, 2004 I know I have down the wiring of the WRX to have its stock foglights switch on and off independently from the headlights (rather than having to always turn on the headlights first before the fogs can turn on and off).. but does anyone know how to do it on the GTs? I am looking around for a wiring guide, but have no luck finding one online. I would love to have the fog lights just turn on by themselves.. just another control-freak thing for me, anyone? Thanks.

agctr Posted August 16, 2004 Share Posted August 16, 2004 Hmm not sure of it myself either. Not even sure on the MY01 as everything is intergrated. You may have to run a seperate wiring loom to the lights and have an independant switch. Adam. Link to comment Share on other sites More sharing options...
Drift Monkey Posted August 16, 2004 Share Posted August 16, 2004 There must be a way to wire it independently.... Link to comment Share on other sites More sharing options...

Th3Franz Posted August 17, 2004 Share Posted August 17, 2004 I know some people have done this to Ford Focii. I think it involved using a relay or something.. I don't know if Subarus would need to have something similar done or not. -Franz The end of a Legacy http://www.youtube.com/th3franz Link to comment Share on other sites More sharing options...
IwannaSportSedan Posted August 17, 2004 Share Posted August 17, 2004 There is probably a signal wire that enables the circuit when the headlights, markers, or even the dash/console lights are on. Find that wire, trick it by connecting it to ignition switched power, or even constant 12volts (don't forget to turn them off) and you'll have your mod. If the circuits are negative switched, then it becomes a bit more complex. Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted August 17, 2004 Share Posted August 17, 2004 I did this to my WRX- I'd imagine the Legacy wiring is different though. Link to comment Share on other sites More sharing options...

I am not going to tamper with the actual switch itself to find it.. I was wondering if anyone else have done this job? Keefe Keefe Link to comment Share on other sites More sharing options...
Trent Bates Posted September 13, 2004 Share Posted September 13, 2004 On one of my other cars, the trigger wire for the factory relay for the fog lights was connected to the low beam headlight circuit. When +12V was applied to that circuit, it activated the relay and the fog lights came on. When the headlights were switched to high beams, or turned off, the relay de-activated. (I might be wrong about the trigger wire polartiy. It is more likely the absensce/presence of the ground connection for the lights that triggered the relay.) The fix on that car was to place a jumper wire on one pin of the relay and connect it to a constant ground. I'll bet that something similar is happening here. I really need to get a look at the wiring diagrams for this car!!! Link to comment Share on other sites More sharing options...

Why would they do that anyway? If I'm using the high beams I want as much light as possible :( Link to comment Share on other sites More sharing options...
mccorry Posted September 13, 2004 Share Posted September 13, 2004 I'd like to get the fog's on with just the parking lamps... and to be able to keep them on with the highbeams.... I'll have to start digging into this, as well.... Link to comment Share on other sites More sharing options...

What you'll need: A few inch of 12ga (or thicker) wire Wire Stripper/Cutter/Crimper Combo tool (cheap at parts store if you don't own one) 2 Spade Lug Crimp Terminals (cheap at parts store) Fuse/relay puller or some prying tool 1. Open your hood and locate the fuse box (Drivers' side near windshield) 2. Open fuse box and locate R13 according to the map on the fuse box cover 3. Pry, pull, or otherwise remove Relay #R13 from it's socket. It is in there tight but it comes out! 4. Cut a length of wire about 2 inches long. Strip the ends and crimp a spade lug to each end. 5. Push the lugs in to connect the two parallel sockets (not the 3 parallel ones). 6. ALL DONE! This modification might cause you to fail inspection if they check to see that fog lights are only on with your low beams and at no other time. I keep the relay in my glove box just in case.[/quote] from focushacks.com but this is usless to us. lol. time to read the rest of the responces Link to comment Share on other sites More sharing options...

Drift Monkey Posted September 14, 2004 Share Posted September 14, 2004 Well...I had it to where I could swtich my fogs on anytime, independent of any other lights, on my WRX, it MUST be possible int he Legacy...somehow... Link to comment Share on other sites More sharing options...

Guest *Jedimaster* Posted September 30, 2004 Share Posted September 30, 2004 Here's the foglights relay- what else did you need? I'd really like to know how to do this. Link to comment Share on other sites More sharing options...
Trent Bates Posted September 30, 2004 Share Posted September 30, 2004 Definitely looks like they are exploiting the voltage differential across the headlight filament to activate the relay! I'll bet that unhooking the LW wire at pin 11 and grounding it will fix the issue. There's not enough information in the schematic above to be sure. It could be that the VL wire that runs through the Front Fog Light Switch and becomes the WR wire is grounded instead. Link to comment Share on other sites More sharing options...
Xenonk Posted September 30, 2004 Author Share Posted September 30, 2004 where DO you get THESE diagrams!? Do you have one for the pinouts on the ECU too??!!!!! ok, I also need the other half of this drawing. I need to know what "B" is hook up to.. my guess if it's the same way as the WRX, you would need to BRIDGE the VL11 wire to LW12 wire Keefe Keefe Link to comment Share on other sites More sharing options...
