    Shift interrupter switch.

    That is a TB 4 the newer 5.7 should be a TB5 not sure if wiring plugs are the same but kind of doubt it. Have seen tb5 modules either on distributor or on port exhaust elbow . My TB5 module is bigger and rectangular with two square wiring connectors not one large single connector

    Shift interrupter switch.

    Yes makes sense but why would merc have a alpha and bravo module as separate parts? I get it for bigger engines but 4.3, 5.0, 5.7 doesn’t make sense unless something is different look up a bravo wiring diagram green white is constant hooked to ground vs going through shift interrupt on an alpha.

    Shift interrupter switch.

    it was my understanding ( could be completely wrong) that bravo modules do not have shift interrupt feture. I heard thus through michigan motorz when i did my repower seven years ago. I did not want to use the Delco EST that came with a partial engine package so they sent me a thunderbolt...

    Shift interrupter switch.

    If you are using a bravo ignition module since it was a bravo tear out the shift interrupt will not work Bravo drives with a cone clutch do not require shift interrupt I think you need to swap a alpha module Did you get rid of the belt driven water pump as well ? Not sure if that can be run...
