Fog lights installation

[Grantus]

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 ?

My negative wires are attached inside the lamp body, for weather protection.

Any live wire to the relays and switch will work, as long as you remember to always turn them off before leaving the vehicle, to avoid a flat battery. If the relay trigger wire is connected to an “ignition on” circuit, they will always be off, when the key is off. Up to you…..
