In this picture I have three possible connections on the chassis I tried to number them 1, 2 , 3 and circled each one.
On spot # 1 , is there where the degaussing plug goes?
On spot # 2, is this where the plug coming off the yoke where the plug with the yellow, green, red, blue wires go?
On spot # 3, there is a large pigtail that came with the chassis that obviously goes there, what is this? There are two possible spots next to each other it can plug into, one is labeled with an H and V in front of it.

Here's spot # 3 with plug removed...two possible connections
