TXDOT states fog/offroad lights and highbeams are illegal together... not fogs alone. Maybe it varies state to state? My Camaro also allowed fogs and parking together from the factory...

I think I'll fix mine this weekend... looks like it's not hard to do... I was planning on enabling fogs any time the key is in the ignition. Only downside would be the minor current draw for the relay if you left the key in the ignition (~30mA).

I'm assuming of course, the 2002 manual is printed correctly.
