I'm pretty sure they're not the same. I picked up a fog switch AND pigtail off an '03 Axiom about six months ago, but ended up giving Billy the pigtail as partial payment for his lift and electrical services. He tried using it on a different Isuzu fog switch and it didn't fit - the buttons look alike from the outside, but the plugs on the back are different. I gave him the matching switch and everything worked great (evidenced by his uber cheap lighting thread).
