That depends on how the signal indicator light works. You might be able to modify the circuit to work with a 2 prong flasher. Why not modify the circuit to work with a 3 prong flasher? Wouldn't that be simply replacing the 2 prong flasher socket with a 3 prong flasher socket? There was a discussion on modifying a circuit to use an older signal switch awhile back. 23 pages is nuts and I'm not sure what the solution was.
