Outer Limits 4x4 Board

Guys,

I have an MK dual cab, and am wanting to finish setting up my dual battery system by getting power into the tray. Has anyone done this before, and if so, where did you run the cable into the tray? I have a plastic liner in mine, so I can see if there are any factory grommets or the like to run the cable through. Im fine running cable from the engine bay to the rear, but if possible, id like it to enter the tray withough having to cut/drill any metal.

Any help would be great.

Cheers

Most vehicles i fit out with 12v plugs in the tub , i usually run the 6mm 2 core down the chassis to one of the tail-lights and gain access to the tub from there. Some do not require drilling, however some do not have access from the tail-light cavity and need to be drilled. I cant think of how the Triton's are setup sorry.
