High beam circuit

Ken is pretty dim anyway so "seam fine" is pretty apt.

You'll keep SS

I'm no sparky but won't you end up with all your lights dimmer than they should be as a result of putting too much load on the one circuit?

You might get a little bit more voltage drop on the circuit, but it may not affect it that much due to the short lengths.

The real danger is turning the wire into a defacto heating circuit, lol.

Take your feed for the input to your relay (30) from the starter or Alternator B+ cable, less chance of corrosion and if you take it from the alternator its the best voltage available on the car,
Added to that a stack of wires from Battery from all your mods looks hideous and is a great place for your auto electrician to start looking for faults.
