    I'd Like To Hook up A Lite For Low Oil. What Wire Would That Be?...
    Red/Purple is 12 volts, but is always energized, even when your motor is off.
    Orange wire is also 12 volt supply, but is switched on by the voltage regulator only when the engine is running.

    If you had an oil warning/overheat buzzer/lamp before, the wire is Dark Blue (or Tan, depending on the model year), and it switches to ground when the oil level gets low.

    Overheat temp sensor wire is Tan, also connects to ground when overheated.

    If you had an MFD with oil level display, the Fuel and oil senders are variable resistance, not a switch. The warning light would need to be set up to illuminate when oil sender (Blue wire) gets to the resistance (somewhere between 33 ohms [full] and 240 ohms[empty]) matching the level you want (1/4 tank?).

    Check the wiring diagram for your model and year.

    Did the round ones have a low oil sensor/warning light?, I know on the '95's I believe they did

    You may be able to;
    What color wire do you have that goes to the oil sensor?
    What year and model is the ski?

    The service manual (1992-1997) is available for download through the tech section here. Look for the link to mattman's web page, then download the PDF (57MB file size).

    Run premix and forget about it.

    Blue is for the oil. But I thought that had a gauge, not a light.

    I should have gone premix when I had the Eng. out I hate to pull it back out to go premix plus I have two skis I would want to go premix on both and there was a small lite on the MFD.

    you just need to pull the carbs to access the oil pump , an led light should be easy to hook up you may still have the buzzer circuit in place under the bar pad? not sure on your model
