Plug the servo wire onto the board on the bottom row of the EXP3 block.

Note the black arrow head pointing to EXP3 pin 1.

The black wire lead of the connector goes into EXP3 pin 2.

The white wire lead of the connector goes into EXP3 pin 6.

That means the middle lead of the connector is in EXP3 pin 4.

Notice here how there is one pin free on the right.
