box on ECU2), pin 45 of connector S55 pin 12. From there
via cable S33 to the D sub-contact S42 on the control lever
S32.
2. Earth reference to the 10V is fed from S2 pin 44 to connector
S55 pin 13. From there via cable S33 to S42 on the control
lever S32.
3. When the lever is in the neutral position P1, P2, P3 and P4
supply 5V to S42 and from there, on to connector S55. The
end positions provide 0V and 10V respectively.
