yeah that part number listed for the fog switch from Delray is correct and the last character switches between F, G and H to differentiate between the different switch combos, i.e
1. TCS/Fog/Courtesy combo
2. solely fog button for and L 3
3. Fog/Courtesy combo
I recently went through the trials of locating a dealer switch in my area and in my experience the switch came brand new in the original box but was without the pigtail, but I didn't need it anyway. I'm not saying this is the case for every dealer, b/c I have ^+1 heard that Delray will give you the pigtail, so best of Luck with that if you need if for your LS/GS. If possible, get an L switch if you just looking for fog control and search for the soldering diagram for the Hella DE harness, its magnificent.
