I can not figure out where how to wire these. For the 6 Way Selector, which post will the starting point? For example, which post is "I" and which is "J" ?

Can you tell me which post is the ones to the far right where I have labeled with the green question marks?

Turn the pot fully one way. Use a multimeter then to check which post is connected to the common. That'll be your starting post, work your way around from there.

Facing the amp with the guts side up turn the selector switch all the way to the right.. Look inside the switch and notice where the detent lands.. you will see it match with a solder tab. Start wire I there. click one click left look where the detent lands you will see it connects with the next solder tab over.... solder wire J there..... then follow same pattern with k,L,M,N and that will do the trick.. the I on the board wire is I on the switch and so on and so on........ hope that helps

yeah, or you can look at the turret board, each wire connects to a different point which is fed off the output of the ef86. i determained which is which by using the capacator value to figure out the tone from thick to bright. i dont remember the starting point, but it goes in alphabetical order.
