Connecting Stealthmax via Stealthmax pcb v2

I am trying to get my SM to work with the printer and I ma getting odd behavior. It seems to use the same id as my t0, I thought I got around that by defining the path, now what happens is klipper never starts because it cant connect to t0 or the SM, or the thermistor on t0 reads a crazy high temp. Disabling the SM config and a hard reboot gets my back into klipper. WHat can I do here?
