On your fuse block there are 1/4" male terminals that I call "taps" that are used to add accessories. These taps are protected by neighboring fuses in the fuse block.
The LPS terminal only has output when the headlight switch is pulled halfway out or all the way out and varies it's output depending on the rotation of the headlight knob. The neighboring fuse protects that output as well as the wiring going to your dash illumination lights, the factory dial illumination light, and possibly heater control lighting.
Below is on my 68 and on the bottom left corner I have a right angle 1/4" female terminal plugged into the LPS tap. This was to add a light for my heater controls and now the light on the heater controls works in conjunction with the instrument panel lighting.

I don't know why I chose brown but if you can, use a gray wire this way as it will match better the wiring color that the instrument panel lights use. Later it might come in handy with that color if one needs to troubleshoot stuff.
