what ide and language you are using? that tx requires only 1 pin to send data. another pin for your button, many pic16f88 will be unused so its a bit overkill, but the good thing it has uart, you may use that to send data, limit your baudrate to 10Kbps if you want reliable transmission...

one is a transmitter. the other is a receiver. you connect the uart tx pin of the remote's pic to the transmitter data input. you connect the receiver data output to the rx pin in the light controller pic.

the tx pic sends data over uart, the rx pic receives data over uart and execute commands
