You can't plug the T-LCM pedals directly into your Logitech wheelbase. But they will work alongside your G25 on PC, as a separate USB pedal device in your racing games. Well most racing games, as there are a few outliners that don't like separate wheel and pedals. For instance Codemasters Dirt 5. But other Codemasters titles are fine including Dirt 4. But for all the 'full on' sim racing titles, support for separate wheel and pedal devices is normal and it's very a common hardware configuration.
