The wire's you're holding in your hand don't look like standard colours so look at the wire colours on the other side of the plug. You'll have 3 wires in your PV courtesy light Brown, Brown/Red and Red/Black. You'll need to run another wire up to the light too, for the instrument lighting. Easiest way is from the back of the instrument dimmer or if you don't have one from the back of the light switch. Look for a Grey/Blue wire.
You can ignore the Green and white wires as they are for the automatic dimming mirror, which if you have this the sensor will be built into the mirror itself. Ignoring those there are only 4 other connections to make.
