There is a landside free bus that runs T7 to TBIT. But you would then have to reclear security at TBIT.
Or you can stay airside and walk from T7 to TBIT. Tunnel T7-T6-T5-T4 then airside connector T4-TBIT.
Checking your bags through or carrying on? Single ticket?
If you arrive on time, you’ll make the walk, but if the flight from EWR is late could be tight.
