That way you are chasing voltage instead of blowing fuses.
While ever the globe is lit the short is present, whatever you disconnect that turns off the globe is the fault.
All you can do is split the system into sections.
If you unplug the connector M96/B102 near the RF guard that will disconnect the rear lights so if the fault is still present it will be in the switching or the front loom/lights
If the fault is in the front you next need to rule out the dash lights, dimmer etc.
Have you checked where the cable for the trailer plug is spliced into the vehicle loom?
Have you had anything in the dash apart recently, fitted a new radio or accessory?
