The direct battery connections can be done as long as you connect the fuses there as they should be.
Let me say here that you should NEVER use a fuse in a brake controller circuit.

Why??? If it blows the controller wont work.

It should have an AUTO RESETTING CIRCUIT BREAKER in the + line so that if it trips it will reset and still give you brakes, Maybe intermittently but brakes never the less A common error which could conceivably kill you.

All other accessories should have individual fuses as close to the battery as possible.

A bus bar box is a good idea with individually fused circuits.

Im not a sparky but have put all the extra wiring in a Landcruiser.

Extra battery and isolator, Anderson plugs and 6 gauge wiring for van batteries, EGT, Auto temp gauge, Low water alarm, Digital engine temp gauge, RVC with dual power supply RVC on caravan.

Dont know about the Tig but was told not to connect to battery in the Passat Bluemotion. Also told dont stuff battery as they are about $800
