Gets stranger. The lamp is still on with the single wire to the sender
unit unplugged. (The gauge does read zero without the car running)
However I noticed the BRAKE lamp wasn't lit. So, I pulled the SINGLE
wire to the DOUBLE prong PDWA sensor and the oil light went out. I
plugged the wire back in and the BRAKE light came up bright, the
ignition light was bright, but the oil light was dim. When I started
the car, they all went out. Anyone have a clue on this one?!!!!
