CAUTION: Forcing LEGO® to connect over a cable can result in damaging the cable and light.
Connecting cable connectors to Expansion Boards
Take extra care when inserting connectors to ports of Expansion Boards. Connectors can be
inserted only one way. With the expansion board facing up, look for the soldered “=” symbol on
the left side of the port. The connector side with the wires exposed should be facing toward the
soldered “=” symbol as you insert into the port. If a plug won’t fit easily into a port connector,
do not force it.
