    The brown wire should be your temp sensor. If it is kicking the rev limiter on, then it may be bad. Check the end of the brown wire when disconnected from the board with a multimeter. There should be no connection to the engine ground with the engine cold. If there is continuity, then the sensor is bad. Replace the sensor.

    You don't need to remove it to test it. Does your MFD display a warning and/or flashing light?

    i dont think so. i did the test and got nothing on all the settings except for ohm 1k im pretty sure this was it and it went to 20 on the meter. all the rest of the settings were zero tho. so is it good?

    Zero or infinite? Zero resistance means a dead short, and the switch is closed which is faulty. Infinite means not continuity, the switch is open, and is still good. What does your meter read when the probes aren't touching anything? When they are touching each other?
