    Connecting prolink to AEM Wideband

    When connecting my AEM wideband to the Pro Link should I connect the analog and canbus connections?

    You'd only use the can-bus connector if the vehicle was using can-bus. Otherwise that part of the wideband wouldn't work if it was an older non can-bus vehicle.

    The analog doesn't get used if can-bus.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I use the CAN bus inputs on the ProLink with the 30-0300. It has better range than the analog signals.

    If you have the 30-0334, that one connects directly to the OBD2 port. And, only works with CAN based vehicles.
