70 Swinger LED turn Lamps

IIRC, you must have the turn signal flasher with the ground wire in place of the old type of flasher also. If I am reading this right, you are still using the old-style T/S flasher? If so, try putting your 4-way flashers on, with the LED flasher only. All your hazard lights should flash. If that is the case, then swap the LED flasher into the turn signal harness & ground it. (Anywhere a good ground can be made under dash should be fine) Your T/Ss should work fine front & back now. You will probably need 2 LED flashers with the ground wires. 1 for the T/S & 1 for the 4-ways. I hope this helps you out.
