Ground the black wire, "X" terminal goes to switched +12VDC, connect "L1" & "L2" terminals to the lights you want to flash.
Have at it!excellent.........mind if i add this to my page? I have two of these to sell. Figure this would help any perspective buyer.
ok.....is there anyone one here that has ACTUALLY done this because the above suggestions failed! flasher now needs to be replaced. please respond ONLY if you know how this works.
The issue is when power was applied ..the flasher made its clicking sound and the selected lights on the aerodynic illuminated but failed to flash. subsequently the flasher failed to operate alltogether. The flasher was the newer type with the ground wire attached and was installed per the directions.
