Sounds like you're on the right track Ken. The Hella spot and fog light wiring diagram's aren't solely for the F6B they were a general use tool that I found very helpful. For instance here in Queensland SPOT lights must run through your dimmer switch whereas FOG lights do not.

I also ran mine through a Relay they are simple to install and once again the Hella relay came with it's own diagram.
