fog lamp re wire

[7783911]

I was thinking about replacing enemic fog lamps with a pair of Marchels and would like to determine how to wire to a separate switch on dash with relays..any ideas on what pickups to use on fuse board (1977 porsche 911). I understand i can re-route from light switch but its frankly a pita to get to that switch and to the actual fog lamp pull knob which is buried behind stereo and amp tucked up under dash. I can use a simple toggle (lit when active) in one of the spare dash holes which i can reach easier

all advice welcome
