I followed the Diagram and get ALL (4) existing original Running Lights (LED Bulbs) flashing in up or down lever position. 6V Power to LED Flasher Relay to Turn Signal Switch is from 20A Fuse on Firewall. When I pull the Head Light Switch out 1/2 way for Running Lights only Left Front Running Light stays on. Seems that I need to integrate the original Head Light Switch somehow ? Appreciate any input here. Thank You
