  • Help please ! Piggy backing SM4

    Hi all so pretty new to the autronics and stand alone management but pretty hands on with getting this setup .
    ive currently got a Marine SM4 which I’m trying to piggy back into a Bosch ME17.8.5 as to take all the inputs needed to run the SM4 on the standard loom

    any suggestions or diagrams would be a great help

    Do you have a diagram for the existing ECU / Vehicle / Jetski ?

      A wiring for your vehicle is needed, I have done it for some Volvo Motronic cars. Also built in a Sm4 board inside a stock Bosch ECU case (also ignition expander inside). Then just snap in the ecu with the map sensor hose.
      Do you got any more info about the car?

        Then make a cross pin wiring in excel, it is worth it !! Here is one I made for a Volvo 960 long time ago. HERE
