Wiring in slim line fans with override switch

[silverzx]

Has anyone got any pictures or in depth details of which wires need to go where in order to do this?

The car has no fans on at all atm but I have some slim lines I'd like to wire into the standard relay (currently off the car) along with a switch (basically provides a live to the high speed part) that I can mount inside should I want to turn them on myself.

I'm looking for details of which colour wires possibly with pictures and or diagrams etc.

Thanks.
