I have a local WR VXL, it has a switch in the boot door lock inside the number plate area, when we open the boot either by key or by the lever beside driver seat, the dome light lits, keeping the light button in the center position. The switch in the boot gives current to the light at front if opens, it can give current to extra light for boot as well in the rear very near to its installation place.
This is just for information only to do the job in the bestest way and to avoid such long wire & connection till front door.
