Wiring diagram for fog light switch

Anyone got one for the square fog light switch that fits in near the hazard light switch? There’s more wires there than I was expecting!

It five wires.
2 black earths
1 2-colour wire is the switch (dash lighting) back illumination
remaining 2 wires are the switched (multimeter quick way conclude the 3 2-coloured wires)

I never did do well with reading wiring diagrams!
Basically, this is what I need to do... see photo below. I want to cut off the supplies harness for the supplies switch and wire it into a dash switch.
There are 3 wires from the relay assembly, not sure what each one does! But need to connect it up to the OEM switch, can anyone help?

Have you not got a multi meter to check out the relay wires ?

Yes, but I was just being lazy
I know the top left 2 wires are the lighting circuit as I already have one of these wires up in the car for the rear dogs. The remaining 3 wires are permanent live, switch and earth. So I’ll just have to check the 3 wires I want to join.

I hate wiring it's just such a ballache or can be especially fault finding ...
