    I feel like I’m going crazy… Everyone with this plug seems to have 4 prongs in the switch part… The only place I could find with someone using 3 pronged one, he skips the 3rd!

    I just need some help with how exactly I need to wire this plug….

    Assuming standard color conventions, i.e., black is hot (line), white is neutral, and green is ground, here’s what you’d do:

    1. Check continuity of the terminals (input to output) with the switch in the energized/on position to figure out which input terminal is connected to which output terminal.
    2. Inputs:
      1. Wire black to the input terminal connected to “1”
      2. Wire white to the input terminal connected to “2”
      3. Wire green to the input terminal connected to “3”
    3. Outputs:
      1. Wire black to “1”
      2. Wire black to “2”
      3. Wire black to “3”

    No, you have to wire in the switch.

    Ground is still ground, Hot goes through the switch, neutral is straight through.

    Ok, that makes sense, but again, that skips the 3rd prong on the switch…

    the switch has two states off and on. When it is off then the center terminal is connected to the other prong on the switch. it is a Single Pole Double Throw (SPDT).

    OOOOKkkk. That makes more sense now.

    so switch side…

    1. brass is empty
    2. gets my black wire
    3. gets a jumper to…

    plug side…

    1. jumper
    2. gets my white wire
    3. gets my green wire.

    ok. explained like that with the 2 state switch, makes much more sense now. Thank you both.

    Doh!  That’s what I get for assuming things.  Thanks to Ryan for fixing my assumption!

    It is my humble opinion that the wiring above (2 red wires) is incorrect.  The jumper from the load out from the fuse should go to the center position on the switch.  If you want the switch to light when powered the bronze terminal (3) should be connected to Neutral (Not ground).  I have attached to photos to back up my opinion.You must look close to see the numbers on the switch photo.
