Fog lights installation

[KIWI]

Ok , Thanks. two wires can be arranged. does the second wire attach to inside the lamp , then to ground or is it attached where I mount the lamp to the bumper and then to a good earth connection on the body. ? And two relays.

I have a live wire under the dash that is NOT ignition activated, it is constantly live, was going to use this wire with a under dash switch to on and off.
Do you think this would be a problem ?

In the olden days, and with most current European cars FOG lamps are only on when the parking lights are on.
IMHO a much better solution.
