2. I then looped the red #2 wire to the battery wire on the alt.
3. I ran the brown #1 wire to a keyed terminal on the fuse block with a resister in the line.
I didn't have a resister so I wired a 12v side marker bulb and harness into the line. (If you have a battery light instead of gauge you can use that) I have the bulb placed so it lights my floor up and serves as my alt/battery light. It comes on when I turn the switch to the on position and goes out when the engine starts. It seems to work just fine but I do intend to run the #2 sensor wire to a junction block on my firewall when I get time.

Does anyone see anything wrong with this setup?

Your wiring will work just fine but if you have an ammeter, that will not work.

You should have a brown wire from the firewall block if you are talking about a 1970 chevy. That wire is the exciter wire that ran to the old external voltage regulator. You could have used it since it already has the resistor wire in it from the key switch. It's nice to have the light to indicate charging or discharging if that happens. Here is how I wire mine.
