Set output 3 and 4 in config outputs to pins 8 and 9 or any other free outputs.

M905 turns ON  output 3
M906 turns OFF output 3
M907 turns ON  output 4
M908 turns OFF output 4

Test and check outputs work looking on diagnostics page before going live and make sure relays are turning on and off correctly.

Thanks,
Brian.
