bright at night

i was wondering if anyone knew where the relay was for the headlight/foglights. I heard that if you ground one of the wires on the relay you can have all 6 lights on (highbeams/regular lights/ and foglamps). I am aware that this would be illegal in just about every state but it would be more for show or long road trips at night when I usually travel. Has anyone done this trick?

Ok, what i'm asking is does anyone know how to make all 6 lights work at once, short of rewiring the whole thing? Anyone done this to their car?

From the schematic of the lighting, The one wire tells the relay for the fog lights to turn off when the high beams are turned on. I guess if you cut this wire it should allow the fog lights to stay on. If not your could just splice the two back together. I have aftermarket fog lights and I have them setup to stay on with the fogs, It is a whole lot brighter than without them Hope this helps.

That diagram is messing with me.. from the one I've looked at.. all you need to do is remove the green wire from it (the relay that is..) to keep all lights lit a all times... seems to be a conflict in diagrams..

If you look at my diagram, the arrow is pointing to the light green wire, That is the wire I was talking about removing. Our diagrams basically show the same thing, yours shows just the fog light system, mine is the fog light system with the high and low beams. It does look confusing at first. So if you just disconnect the Light Green wire going into the fog light relay and ground the wire going into the relay, then make sure you tape the other wire so it does not touch antything, it should work.

so is there a way to wire it so you have your high beams and low beams on at the same time? or do they do that already when you click on your highs? I don't have fog lights but im going to add some tomorrow

typically they don't do that, since the bulb would over heat and explode with the extra heat from two elements lit up...
