For assmebly, first solder the 4 wires to the connector (silicone wires are perfect for their flexibility.
Remove the seal from the SP17 back housing and place it into the body. Then screw the body onto the connector. You can now shorten the wires and solder them to the boards.

Use double sided tape to mount the boards into the body.
