Yes for the "battery" wires on the controller to go to the battery lugs. Not for the "array" wires and then have the controller between the converter and battery. You want the converter and controller in parallel on the battery.
In the 90s it was common for the controller output wires to go to the 12v connection at the back of the fridge as a way to get to the battery. Meant using those skinny wires the fridge has. Much better to go to the fatter wires at the battery lugs on the DC fuse panel. (Best is to get the controller close to the battery and go directly to the battery posts)
