Connector 5 ......"A+"
Connector 6 ......"A-" (thesetwo look suspiscously like theycould be the DC outs to the motor)

Ok, now Connector Block 2
Connector 1 ......"K1"
Connector 2 ......"K2"
Connector 3 ...."P1"
Connector 4 ...."P2"
Connector 5 ...."P3" these P1-P3 seem to go to the speed control pot & match up with the wiring diagram, so these ones at least are solved!
Connector 6 ....."P4"
Connector 7 ....."P5"
Connector 8 ....."P8"

There is one little connector block with just two connections at the other end of the board (near the Output thyristors)...one connector is labelled K1 & the other K2.

These machines share common wiring between machines.

L1 and L2 are mains
A+ A- are the motor connections

P1, p2, p3 are the pot

K1, K2 Usually wire to the start switch as an inhibit so that if it trips you have to switch start off then on again to reset.

The one I can't help with for definite is P5 and P8.
on the X3 these have a jumper fitted.
