is it just wiring the fog lights HIDs to the switch to the battery or what?

You're putting an HIG kit in there? I suggest wiring that switch from the battery through a relay and then from the battery to the relay to the HIG kit.
Something like (not to scale

)
|------|
|--87--|
|--87a-|
|86--85|
|--30--|
|------|
87 - 12V -> Relay to HIG Kit 12V
87a - empty -> Don't Use
30 - 12V -> Battery to Relay
86 - Gnd -> Relay to Ground
85 - 12V -> Switch to Relay
On your HIG kit, you'll have the power coming in from the relay and then exiting via a Gnd wire in the kit. The switch will have a 12V power source (doesn't have to be directly from the battery, only a small current is needed for the relay) that, when in the on, will complete a small circuit that trips the relay to allow the larger ballast current to flow.
The above should be right, just match the numbers on the relay with what is shown above and you should be good. Just don't use 87a, otherwise you'll reverse the flow and the kit will only come on when your switch is in the off position. If you get a 5 pin relay, all the above will be there. There are also 4 pin relays that leave out either of pin 87 or pin 87a.
Hope that helps.
PS - I still don't encourage HIG kits in factory fog reflectors. If a stock projector from, say, an IS300 is modified to have the correct focal point, then that's not bad. Reflectors, however, are just glare buckets and it's more pronounced with HIG kits. Basically, if you drive with them on, you'll be blinding someone.
