    Just throwing this out there. I have electric breaks with a break a way on my camper and have a blue wire which needs to be connected to the positive to operate my electric breaks. Jayco I believe only uses hydraulic breaks unless the prior owner changed it out. Definitely try and follow the wire.

    The blue wire should not be connected to positive, it should be connected to your brake controller.

    If you have an ohm meter, measure the green wire to the chassis. It maybe connected to that. In DC circuitry the black wire usually denotes the chassis wire. Again, use your ohm meter to see if that is connected to the chassis. If not, check the white one. Do not just connect wires to the battery without knowing what is what: You can do a lot of damage or even start a fire.

    Green wire many times is used for the running lights around the pup.
    Have you connected the 4 pin connector to your tow vehicle to verify all the lights work?
