Hopefully this quick write up will save someone time. If you are trying to make sure each of your LED lightbulbs in your Dash cluster are plugged in correctly (Positive to hot)
Using Don C's pinout diagram, hook two test leads up to a 9 volt battery. Touch the Positive lead from the battery to a lead where the wire harness connects that corresponds to the light you want to test, then touch the negative lead to the side of the plug showing negative on Don C's diagram. If your LED doesn't light up, take out the bulb socket, turn it 180 degrees. Try it again. That's all there is to it.
