Install of PIAA Lamps onto 2003 Tacoma

[rocketeer928]

I recently purchased a set of PIAA 001 Solitaire Series fog/driving lamps for my 2003 Toyota Tacoma. In the harness installation instructions the 7th step states to use the supplied connector and connect the switch power wire (H) to a power source. I have some questions about this step.

Can the lamps be operated independently of the high or low beam headlamps? If so, does the switch power wire (H) need to be connected at all?

If the switch power wire (H) must be connected to a power source is there an alternate source other then the main headlamps? If so, where can the connection occur, such as which wire location and wire color?

Thanks - rocketeer928
