Merc. Mag PT wiring questions for 100W

I'm building a 100W kit, I'm using the MP-100-460 toneclone.
Just wanted to make sure about the wiring before chopping them.
This MM trans has 2 green wires and I wanted to verifiy which one is the center tap for heater winding. Is the correct wire (the one that gets grounded on the nearby can) the green wire (Filament) from the primary side? Just wondered why the MM schem. shows it in between the black heater wires on the secondary side.
Now, the green wire on the secondary side near the white is that the bias winding common tap?
On this trans. which of the 14 wires are not used and should be cut short?
When you have wires that aren't being used what is the best way to cut and stow them so it looks pro?
Any help is appreciated b/c.....
I am itchin' to solder :!:

i wouldnt cut the 3 wires that arent used. wrap them up and tie them off after you cut and shrink wrap the ends.

I'm installing a MP100-460, what are the brown wires and are they just shrink wrapped?

Hey Rockstah,

On the bias output, does it matter which side is grounded?
