Dual Batt in tray - where to punch cables thru tray?

[rivmasta]

Hey all,
Ive put a 2nd battery in the back of my 2008 dual cab with canopy. Now I need to run cables from main batt to DCDC charger which is mounted at the front of the tray, accessable throug the canopy window.

Where is a good spot to punch through the front of the tray? Any suggestions on securing the cables?

Cheers,
Riv.

No need to drill there is a gap under the top corners
