What worked on my car is this: On a three prong flasher, connect the two outside prongs to the mounting location of the two prong flasher in the fuse panel with jumper wires, then connect the light to the center prong and ground the light. Locate the three prong flasher somewhere with a wire tie or tape. The center prong is energized when either of the two outside prongs are, it then sends the current to the light. I used a painless system and this arrangement worked for me. Wiring is definitely not my strong suit. Good luck, Bob.
