The two old fog mod threads either had small pictures or no pictures. So I merged the two threads and created this one. Thought it would be helpful to the legion of new 1st gen IS owners out there and the ones that will join in the future.
Credit goes to tony and irv_usc for their original threads:
Pros and Cons to this method over the original:
1. The Fog Mod circuit is independent of the ignition circuit. If crap were to happen with the fogs that causes a short in the circuit with the original fogmod, your car will not start. This can cause a panic until you realize the fuse is blown. (the add-a-circuit portion can be added to the original method to fix this, in case you were wondering)
2. Cost of the Fog relay if you happen to break the prong while bending it
3. Damage caused to the fuse panel by forcing an extra wire in the slot.
1. Costs more than the original. (approx 8-11 dollars for the Add-a-Circuit, 2-4 dollars for the quick disconnects, etc)
2. There is more work. More crimping of terminals, plus filing down the quick disconnects to fit the original relay plugs.
1 Mini Add-A-Circuit (Found at Pepboys, Autozone or partsexpress.com)
3 x Male quick disconnects
4 x Female shielded quick disconnects
2-3 feet of 16 GA. Wire
1 x 7.5a mini fuses:
ratchet with 10mm fitting, wire strippers, crimping tool, fuze puller or tweezers
Step 1: On the passenger side, pull up on the door plastic runner along the door sill. It is attached by clips and should pop right up with ease.
Remove the kick panel cover to expose the fuse box. This is attached by metal clips, and requires a little more force.
Step 2: Remove these two bolts (Size 10 Metric).One is on top one is on the bottom.
Step 3: Lift up on the fuse panel and pull it open to see the Fog Relay.
Step 4: Make three 4-6" wires with a Male quick disconnect on one end and one Female quick disconnect on the other, and one 12-16" wire with one female quick disonnect on one end only. (You will need to file down the male end of the wire so that it is the same size as the corresponding prong on the Fog Relay)
Step 5: Crimp the Mini Add-a-Circuit to the end of the long wire. (In this picture I already added the 2 7.5AMP fuses to the mini add a circuit, but you can do it later on in the instructions).
Step 6: Plug the wires onto the Fog Relay and slide the Fog Relay back into the area behind the fuse panel, then plug three male ends into the corresponding slots of the fuse panel (the three plugs shown are the only ones used, the fourth is empty). You may have to file down the male terminals here if they don't fit. When done you should want to wrap the terminals here with electrical tape.
Step 7: Pull the last/bottom 7.5AMP fuse from the middle column (this is your ignition fuse) and replace it with your mini Add-a-Circuit (don't forget to add 2 x 7.5amp fuses to the mini add a circuit, otherwise your car won't start).
Step 8: Turn the key to the "On" position and enjoy your fogs. Make sure the Highbeams aren't on. (my emblem is missing because i'm currently black pearling it.)
Step 9: Put your car back together.

WARNING: Do NOT combine this mod with the highbeam mod. (The one where you take apart your steering column and ground 1 of the wires so that you can run the headlights/fogs/highbeams all at the same time. IT MIGHT FRY YOUR FUSE BOX.
