    Considering the OP's camper is a 2008 the powered cassette toilet it has is likely a Thetford C402 rather than an older C2 or C3. To establish just what these 2 wires are for my first step would be to put a voltmeter (in the DCV mode) across them to establish whether there is +/- 12 vdc and whether this voltage is always there or intermittently. If there is no voltage at all, under any circumstances, then considering the location they are likely wires connected to the toilet motor.

    Been following this thread and have to say, crappers should not be this much trouble.
    Thankful for my simple, nonelectric hand pump/flush model.
    Good luck Rosebud and really hope you can get it working.

    Is the outside light on the left side of the door as you enter the camper. If so, you should be able to access it's wiring through the cabinet behind the cassette.

    Thanks! Of course we can always just pour water down the thing, but it would be nice if it functioned as intended once in it's life.

    Yes, the light is on the left of the door. I'll look into that idea, thanks!

    Thanks again GF. I'll dig out the multimeter and give it a whirl.

    99.9999999% the red and black wires are to the pump. Just put 12V to them briefly and listen for the whir of a pump motor. Then its confirmed.
