Maybe through the venting ports behind the window on the picture? On a GQ that would be on the last column as a separate piece. In yours it seems to be part of the window frame.
My experience is with a GQ, so yours may vary. On the GQ, if you remove the tail light, the cable would be right above it. To route it forward into the cab, I would then remove the internal panel over the rear wheel well and go from there.
I recall this subject came up not long ago but I can’t find the pics I posted then. I found the neatest solution was through the vent but you have to remove the vent and from the inside drill through 2 layers of metal just behind the rear seat belt cover.
Where it enters in the pic it drops down first then comes back up to enter the cabin so no chance of water entry.
This is what I done. Those vents have a perfect cavity to feed cable through to the internal rear quarter (where my battery setup is ).
When the cable enters the plastic grille thing it goes up before it S bends over and then feeds downwards into the internal cavity. So water drip in through the cable is not possible.
