I'm putting the Spark Plug together and it's the first build I'm doing with the LED circuitry on the PCB.

My LED is going to have to be wired up (rather than soldered directly to the PCB). I'm a little confused about how to wire it. do I wire the positive end of the LED to the square 'LED' hole on the PCB and then wire the negative end of the LED to the top left post on the 3PDT switch?
Do I just not use the Ground hole on the PCB next to the square LED hole, or do I have to wire the negative end of the LED to both the ground next to the LED and to the top left lug on the switch?
I'm using the basic wiring diagram for wiring my switch.

the basic wiring diagram says if the board has LED on it to "connect the 'sw' pad from the PCB to the top left lug on the 3PDT instead" but I'm not sure what they mean by the 'sw' pad.
Thanks.
That one doesnt have a sw pad on it per the schematic, but the LED has +V and a 4k7 resistor on it. So you'll want Anode(+) wired there and Cathode(-) wired to the switch as you described.
a couple of ways to remember which is what.
If its fat and its flat, its cat(hode)
CCD -> Cathode Current Drains.
Cool, Thanks.
Hopefully I'll get this put together tonight.
