Power from battery to back seat

[Grinch1007]

Hello all,

 

I have a 2016 Sierra 1500. I am installing some communication equipment. I am looking run a power cable from the battery threw the fire wall to my back seat. Unless there is a constant i can access in the cab. Can someone please tell me a good access point in the firewall please?

 

Thank you

Chuck
