kjg26,
That diagram is correct, look at it a little closer. The wire to the coil side of the relay is from the low beam wire to the head lights. When the low beams are on power flows to the coil closing the relay and turning on the fog lights. He just included a switch in the circuit so you could turn the fog lamps off while the head lights were on if you needed to.
Hope this helps

so the four prongs on teh relay would be, ground, to accesory, to power, and to low beam wire. a switch could go between the low beam wire and the relay if i wanted that option. is that correct? thanks

Yes. Here's a picture of the most common relay they sell. I think Walmart even sells it. Some of them will not have the 87a terminal, but you don't need it.

Hook up to the 87 contact to be safe. (in some relays the 87 & 87a contacts are electrically connected together inside the relay at all times, there would be a slightly different picture on the top of the relay then the one posted above.)
Hope this helps

so this red wire with black stripe is coming out of the steering column? wouldn't it be coming outta where the headlight switch is? just take off the panel and look? will it be obvious or covered?
thanks

There should be a bunch of wires coming out of the bottom of the steering column. See if you can find that correct colored wire. To make sure you can get a meter or testlight and see if it has power only when the headlight switch is on, and the dimmer switch is in lowbeam position.
