So this is the relay I was going to use:

Headlamp Relay

So looking at the above diagram and comparing my wiring plan (hand drawn) above:

So is this an appropriate plan?:

1) Red/yellow wire from toggle switch connects to 86
2) Long wire direct from +battery terminal connects to 30 (with an inline 10 amp fuse) - is there a closer location from which I can draw power (from the control box?) rather than running a wire to the battery?
3) 85 Grounded to chassis
4) 87 Connects to foglamps

Many thanks all!
