I was thinking about replacing the stock fog lights with 75 watt bulbs but first I wanted to know if that would screw up the wiring harness or anything by doing this.

 

no. you should be fine. my friend switched out the bulbs w/ nokya artic white H4 bulbs for about 6 months now and no problems.

 

It might cause too much heat in the fog light bulb housing and either burn out the bulb, or melt the harness.

 

i bought a pair of piaas 85/135 watt plasma bulbs, no problems yet 1 month.

 

and before that i had cheep imitation hid fogs and after a few weeks one of them burnt out, as usual from ebay.

 

i put in Naxos H3 bulbs into my foglights, they are either 100 or 80 watt, i forget, but anyway, the glass of the foglight cracked after a few weeks from all the extra heat.. needless to say I went back to stock bulbs

 

awesome. damn i want mad bright bulbs with no usual hassel well n oproblems on this pair "knock on wood"

 

narva 85w yellow h3.. no problems yet but its only been 2 days

 

there are some PIAA bulbs, i think they are called Extreme White, which are stock wattage, but have the super white hid look to them.

 

piaa.com and there like 85-135 watts

 

I thought about the PIAAs, but they are more than I want to pay.
