HeNe Polarity Connections!

[Rhith]

Just got my HeNe and wanted to make sure I'm hooking everything up right before I screw something up.
My guesses as of yet are the red/yellow wires that are twisted and the small black wire go to my power supply to give it the 5-6V.
As for how to and where to connect the rest to the HeNe I'm lost.

Thanks in advance!

Red + red&Yellow = positive power connection
Black = negative power connection
Fat red wire = anode of the tube
Skinny back wire (with ring) = cathode end of the tube

Peace,

The end shown in the picture is the NEGATIVE end of the tube, the black longer wire goes to this end, thick red end goes on the other side..
