ABY wiring?

Hello.  A little while back, when I first got into this whole pedal thing, I cannibalized my morley ABY box for switches, etc...  Well, silly me, I've found a use for it after all and am trying to put it back together.  I need to know where the wires connect from switches to board.  Does anyone have one of these that can take a look inside and draw me a quick diagram? 

The wires are numbered on the schematic, so if you could just tell me "lug 1 to wire 10, lug 3 jumpered to lug 6," etc... that would be great.  If you do this, lay it out like so:

1   4
2   5
3   6

Thanks a bazzillion!!

::nudge, nudge:: Anyone?

Okay, let me rephrase.  Can anyone show me how to wire up two DPDT switches to run a passive A/B/Y box?  I have three stereo jacks, two pull down resistors, and two leds.  Actually, here's the schematic.  Wiring please???

I don't think I understand. You have the wiring RIGHT THERE in the schem. What are you asking for?

he wants to know which lugs on the physical switch correspond to the schematic.

but i'll bite anyway.
1  4
2  5
3  6


does that help?

If you need a pic of the guts, let me know and I can take one for you.

Photo - Yes please. 

Thanks for the responses everyone.

And I understand how to match up the schematic with the switch in theory, but I've seen switches wired quite unusually before, and this one in particular has some lugs jumpered within the same switch.  It seems that the wiring would be very straight forward, but it isn't.  If anyone can explain this I would be very greatful.  Why is it that in a true bypass with NO LED, the switch can't just be wired:

input jack to pin 2, input to circuit pin 1, output from ciruit pin 4, output jack from pin 5, pins 3 and 6 jumpered.  This should allow true bypass, but I've seen layouts where the wires go to other pins and still others are jumpered when this seems to be the easiest way.

Thank you very much.  I have an older version of this pedal that doesn't have the shielded cable, but rather traces in the PCB.  I'm pretty sure I've matched everything up correctly using your photos and the schematic.  I'll be wiring it up within the next few days, so I'll let you know how it goes.  Again, thank you very much.

You're welcome... Just remember to return the favor to someone else (especially the newer members)


pay it forward, and we can all make this forum an even better place :)
