The only conclusion is that it must be a negative ground / trigger type of switch... or would that be positve... Seems opposite of what I need.

I am trying to wire up a set of Hella Black Magics that I have mounted. As per the wiring they came with, I'll be using a standard 12V relay. The switching mechanism will be a 12V trigger from a 12V tap off of the high-beam side of the headlights. HOW DO I MAKE THIS WORK WITH THE FACTORY (fog light) SWITCH, I ASK YOU? : )
Please... someone?

Thanks in advance!
Ummm...Maybe there's no current to your scource until the high beams are on ?
Just a "maybe".
