insert four M3x35 screws into the holes, flip the board over, and then put one 25mm spacer on each screw. This picture shows only three spacers on four screws.

Mount the switch plate on top of the screws. The cables should come out along thie purple arrow, NOT go between the screws as this picture shows.

Remember the mirror images? If the diagonal part of the wood is on the left...

...then the switch must be on the right. On the other motor mount we will do things mirrored.

Put the motor on top of the switch plate. Not the direction of the wires coming out of the motor should be on the same side as the diagonal part.
