A stupid question: Switched Reverse mod wire colors = ?

[frizzen]

I have seen the diagrams for the No Reverse mods, but I run clones. So Red, Black, Blue, and Yellow; mean absolutely NOTHING to me.

I'm going to do it as Switched Reverse Mod.

I think I have to cut the 'F' wire (?)

I know I run whichever I cut to an outside pole on a 3pdt switch. Then center pole on the switch goes to the motor can. Then the third pole goes to the + battery clip.
