Slurpee Schematic Question

[skypn]

I'm looking over the schematic and I just can't figure out what the symbols "pin" and "LC" mean as far as connections. I understand VB, VC, IN, OUT. Are all the "pin"s connected? Then I'm lost seeing one of the "pin"s is connected directly to ground, making no sense (to me) for R1.
TIA

Those pins are for wire connection pads on the PCB. So, they are for wiring input, out, ground and LED to a 3pdt.

Kinda thought that *might* be it. Thank you
