Here is my DIY tester. Just used some old speaker wire and a turn signal bulb I had lying around.


Connected one end to the ground connector in the engine bay.


Testing to make sure my tester works using the positive cable for power.


So I first tested the red/white wire Tom thought was the one I was looking for. Guess what, he was correct. Thanks Tom!
