My wideband will work but not perfectly so there's a set of dual widebands.
If you're referring to switching from analog to digital CAN based widebands then you don't use the old factory O2 sensor connections as discussed above. Those go to analog 0-5v inputs on the MS3. Instead you'd use the Aux port on the ECU and wire into the CAN L and CAN H wires. Just a simple two wire network hookup.
