Dome Light wiring

[jeepxj]

Anyone know where the wiring runs. Right or left down the back or on the top down the side. I have no power to the light and have to track it down.
Thanks

From the dash, it runs under the drivers side lower doorplates to the drivers side rear corner, then it runs up the rear pillar along the back of the cab up to the light.
