    Hi all,

    I have a little experience with electronics but this is a little over my head.

    What I am trying to do:
    I have 2 connectors with 5 pins each. Connector 1 will have 1 active ground signal at a time. Connector 2 needs 12V depending on which ground signal is active.

    How would I approach this? Any help is greatly appreciated!

    Does that mean that one of the pins on P1 will be low at a time? And does that mean that one or all the pins on P2 will get 12 volts as a result?

    What is the power requirement for the 12 volts that gets switched (12 volts at how much current)?

    Perhaps our OP needs something like this:

    I didn't show reverse-EMF diodes on the relay coils.

    The ground for the connector on the left must be common with the ground for the 12v supply.
