adding 8 ohm jack question

[TWANG]

I think I did this right.. adding an 8 ohm jack.. red wire to tip.. black ground over the jacks tops to grnd.

but how do I get the NFB connected..

seems like if I connected it off the 4 ohm jack it would send the signal to whichever was being used..

 

but I want to double check with you geniuses..
