    System link gauges.

    I was my understanding these are plug and play. I pick up a used one and its not working. Wondering if im missing something?

    Where did you plug it in to?

    And what Smartcraft Instrument (primary) do you have?

    Mercmonitor level 1. I just grabbed a plug it would fit and plugged it in.

    Make sure you are plugged into the black MercMonitor Harness (and NOT the blue harness).
