    In Need of Someone that is Familiar with 12V Wiring

    I’ve bought the eas switch kit for my CTS2.

    i’ve wired a dump valve into the CTS2 so I can dump my airbags down to five psi after towing without having to hold down the bleed valve.

    I'm wanting to be able to use the switch to activate the pump for my air bags through a relay. Very simple but I’d like to still use my momentary manual switch to add a little pressure if need while driving without playing with the screen.

    Is there anyone on here that may scetch a little diagram of how to do so?

    I could do a little trial and error but I don’t want to take a chance on frying my CTS2.

    Thanks,
    Andy

    If I read this right, you want to activate the same relay coil with 2 separate switches?

    Assuming both switches are electomechanical, you can feed the coil on either side.

    Open contacts won't feed back.

    I'd draw a sketch but I need to sharpen my crayons. (engineers joke) I think you get it.

    Would it be all right with you if I drew a little sketch and had you approve?

    I think I have it figured out but a second opinion would be awesome.

    Just looking at what you have and what I think you are trying to do I believe you want the momentary switch off the N/C contact of the relay.

    So with the power switch on, when the green wire from your EAS energizes the relay coil it will power the compressor on through the N/O contacts.

    When the EAS is not energizing the relay coil you you can turn on the compressor with the momentary switch through the N/C contact.

    See very rough sketch.
