Eighthtry posted:So I guess my question should be is where do I hook up my B post and where do I hook up my C post.
If you want 16 volts to the 5133 plugs, use "C".
"A" to the common / outside rails / lockon clip "2".
"U" to the center rail / hot / lockon clip "1".
"B" does not get used in this connection.
