There's a thread from me about 5 years ago. I put a set of Hella 500FF's in the stock location (above the bumper). To all the other responders, remember the OP has a 95. Which has the fog lights mounted on the flat top of the bumper (in front of the grill).
If you take the grill off you can see the bracket mount bolts, which means you can then get to the nuts that hold the original lights on the brackets. From there you'll see how to mount the Hella's (or whatever you choose to put on there). The wiring is even pretty self explanatory.
[EDIT] Here's the thread. All my pictures were on my hosting which went belly up, so no piccy's. But I think I explained it pretty well at least.
