  • Do I need an external relay for Sumicom + P1290?

    Ordered 2 and just received from mp3car.com

    I have 2 sumicon computers I wish to connect to.

    How can I tell if the p1290 I have does not require an external relay?

    How do I hook this up to the sumicon (I have already soldered the 2 points from the sumicon power switch and have a wire with 2 leads out the back)?



    Thanks.

    Jesse,

    ALL P1290s have an internal relay. You don’t need an external relay.

    How do I hook this up to the sumicon (I have already soldered the 2 points from the sumicon power switch and have a wire with 2 leads out the back)?
    Simply connect your two wires to the green & black wires on the P1290 J2.



    Let me know if you have any trouble.
