So I live in South Carolina isn't rare to be wearing shorts at Christmas. Was looking at simplifying my b2b. If I'm not worried about running the heat can I cap off the hoses and remove the big box under the dash. Ithanks

Heaters were all dealer installed options up to the mid 50s.   In fact, some cars did not have the necessary holes drilled and tapped on the engines.

Rather then cap, I just ran the rear  heater feed line right to the pump, that way I wasn't worried about trying to make a leak proof stop in the system , it just flowed in a loop....but up here you need heat in the spring and fall, so I found a better heater and put it back in.

If you connect the heater port at the back of the head to the return port at the water pump you have created a radiator bypass loop. If you connect your hoses like that hopefully you had a shut off valve that was closed.
