Where's a good interior place to tap into the parking light signal?

I want to add LEDs that come on with the backlights of the gauges and radio. Because it will be low current, I was going to run a MOSFET off of the parking light signal to control them. My first thought was the main harness, but that seems like it would be a pain with all the other wires to dig through. Is there a smaller harness in the steering column that would be easy to tap into and run under the dash?

Why not just tap into the headlight switch harness in the steering column?

I was thinking of doing that, I'm just not sure what wire it would be. From what I've seen, it should be white/purple. I can't find a pinout for it, but I could probably figure it out with a multimeter. I also found a circuit labeled "PANEL LAMPS DRIVER" which may be an easier choice.
