Focus Electrical Issues

[AndyJones2201]

I have a 2006 Focus Estate and am having some electrical issues and need a pointer to either a relay or an earth.

Issues are:

When lights are off, side lights and dash lights come on when the brake is pressed.

When lights are on either side or main, brake lights are illuminated but still grow brighter when brake is pressed.

When lights are on, engine will idle when ignition is turned off for about 5 seconds unless the lights are turned to off within the 5 seconds, then the engine will cut off.

I’ve had a quick look for a wiring diagram but have only been able to find a generic Focus diagram. Does anyone have a diagram for a MK2 2006 1.6 petrol focus (estate), or can point me to a specific relay or earth?
