(ET) wiring diag help needed...

["Dave & Deb" <daveb drizzle com>]

I've got the alltrax in and working (finally!) and am now trying to figure
out why my PTO doesn't have any juice.  There's no power at the socket.  I
may have removed a wire or 2 too many during the conversion.
Now i'm looking at the wiring schematic (pg 3-3 and 3-4) and for the PTO
contactor see wire 2 to disc and wire 3 and wire 20 to something labelled
SO-1.  what is SO-1??

I suspect I eliminated too many wire 13's it looks like wire 13 supplies
voltage to the PTO contactor's coil?? On the coil diagram of pg 3-4 one
side of the coil has wires 13-04, 13-06, 13-07.  are these, the 04, 06, 07
pin numbers??

thanks,
