I installed the Hella lights last week. I found the the red CPF wire, snaked it through a wire loom, and spliced an extension to the battery. With the red CPF wire was a blue wire marked FOG with a connector on it. I found another blue FOG wire under the hood that comes from a solenoid there and connected it to the FOG wire from under the dash. I couldn't find a good route for the wire so it is going under the dog house for now. The recommended switch works fine, but does not light up. I think it needs power for the light, but I'll leave it as is for now. The lights only come on with the key in the run position, so I am not too concerned about leaving them on by mistake.
I roughed in the focus in the driveway and the seem to be about 2xs as bright as the factory headlights. I haven't been on the road at night yet, but I am sure that once I get them dialed in just right nightime driving will be much safer and comfortable.
Thanks to all for your help.
